ICE BEAR PST150H TRIKE

[als01seville]

Hi everyone, I just bought a Ice Bear PST150H Trike. It has a 157QMJ engine rated at 149.6ccs. It revs out at 7500 Rpms and if you hold the throttle you will hear a "BURP" then you have to back off the throttle a little. Problem is that at 7500 Rpms I am only doing around 45-47 Mph. I need just a little more Top End like 5 more MPH to keep up with traffic. I do not want to go into the engine and or make big changes. Would changing Variator and say Slider Weights get me some more top end. I know going to little heavier weights will get me to speed faster at Lower Rpms, so does that mean that when I reach 7500 rpms my speed would be greater as well.

Any suggestions and or anyone familiar with a CY6 157QMJ engine.
Thanks guys I am a New Guy with Scooters but I am mechanically inclined.

Heavier weights will slow your accelleration, but possibly increase your top speed.
Use the magic marker process described in other posts to see if your variator is using it's 'full capacity'.
In my case, an aftermarket variator with stock roller ramp plate with slightly lighter weights, 12.5 to 12g, got me a sustainable speed that I could only hit occasionally before.

[usfmarine]

I'm assuming your trike is heavier than a standard 150cc scoot. You may not have the power to hit those higher speeds.

were you on the rev limiter?

The other day I talked to a Vespa and Piaggo Scooter mechanic and I told him about the "BURP" at about 7500 rpms. He told me to adjust the air/fuel mixture that it was leaning out that I need more fuel. So i adjusted the air/fuel mixture turning it counter clockwise an 1/8 at a time for about 1/4 and the rpms went up. So I left it there lowered the idle to around 1500 rmps and tried it again. This time it reached 8100 RPMS before it "BURPED" but by this time I was doing around 52 mph. I would like to be able to do 55 so I am almost there.

The Trike weighs 353 lbs I weigh 180 lbs and it holds 4.8 gallons of fuel. They say it can do 55+ depending on the weight of the rider. But I also must mention that its brand new and I only have 270KM on it which is about 200 U.S miles.

Also I do not know what you mean about "WERE YOU ON THE REV LIMITER"? I do not know if it has a REV LIMITER, the manual only says 8.5 Horsepower at 7500 RPMs.

Also about the Variator where is the post about the MARKER to check if the BELT is going all the way up the Variator.

I am going to take the Variator out and check what grams it currently has. My pickup is pretty good from the lights and stop signs. It jumps right up to 5000 when I crank it to get to say 25 miles per hour and 6000 RPMS to hit about 35 miles per hour. It pulls pretty good just my top end would like a little more.

the rev limiter does what it says , ever hear a kid on a bike or tuner car floor it and hear a bing bing bing noise, thats your rev limiter, it limits your rev?s

draw a line in your clutches top to bottom as it wears off it will tell you how far up the belt is going,

[als01seville]

I started this when I joined and haven't updated it. I have been updating the VARIATOR POWER. So I will update this for anyone with a Trike. I thought I was getting to around 52mph at 8100 rpms but it was really 49mph and at 8100 rpms the engine is screaming. The police once in a while put up their Speed Radar Trailers by the Park down the street from me to remind the people they are going over the speed limit and I checked my speed with it.
Since then I put a Prodigy Racing Variator & Fan with 12g weights and I must say what a difference. With the Racing Variator the highest Rpms now are 6900 and its doing 54mph. I check it with the Speed Radar and its right on. I love the low rpms the engine is not screaming and it will save the engine and the accelration is great, it gets up to speed much quicker as well. Around here the speed limit on the main streets are 35-45 and I keep up with the traffic. They are not going around me cause I am going slower than the speed posted. As a matter of fact if the speed says 35 they are doing 40, 45 they are doing 50 and so am I.

I have the short case 157QMJ 149.6cc motor that takes the 743-20-30 belt. On the new Variator which is about 1/4 larger than the orginal and there is still 1/8 of an inch still left on the larger Variator. I tried a 750-19.5-28 belt which is a little longer but that slowed me down by 3 miles and a little slipping at slow speeds and giving it a little throttle so I put the 743-20-30 belt back on and love this setup.

Sure glad to hear that all worked out well for you on this set up but wished the 759 belt would have worked too.

I still feel like that if one put this belt on and then went to heavier weights it might work out with good acceleration and a tad more top end. Also by taking off a tad on the center shaft one could with the extra weight force this belt all the way to the outermost OD of the variator! Be something to play with! Also putting a stiffer clutch spring might be of help too!

Heck it might even be worth trying by just getting a set of cheapo 14 gram weights off of Ebay or even taking your old set of 10g weights, putting some JB Weld in them and cleaning them up to 14g a piece but you need a gram scale for that and Marine gave a link to a good cheap one at Harbor freight for that!

I know if I had this short case with the way I am I couldn't stand it and would give it a try!! LOL LOL JRR

[rapidjim]

I would like to know more about your trike. How does it handle? Any problems with registration? Do you like it? How well does the reverse work? Tech specs from your owners manual would be nice also.

My Roketa sales rep has parted ways with Roketa and is now selling Ice Bear, he sent me some info to intice me to buy from him, but I would like to know more from a buyers point of view.

Thanks

Hi Troops, As I mentioned before Me and my brother-in law are a little disabled both of us on the left side. He had a Stroke 5 years ago and me I got shot up in Vietnam. We wanted to be able to cruise around the Suburbs of Chicago and needed stability when stopping and something that would go about 55mph. I found the two sites Ice Bear and Roketa on the internet and ordered two of them from a BANDIT in California which are not in business anymore. I won't go into the details cause its a long story but BE WARNED check out the dealer FIRST BEFORE YOU ORDER AND ONLY PAY WITH A CREDIT CARD "DO NOT TRANSFER MONEY". The Trikes were going for $2,499.98 each but they had a deal, 10% off if ordering more than one and doing a WIRE TRANSFER. We ordered 2 PST150H Trikes and we got them for $2,249.98 each Shipped.

The Trikes are more than we expected, as you can see the body is just like the Honda Reflex. The body parts have a very good fit and its a sturdy Scooter, its a full size Scooter like a 650 Burgman or any of the other big scooters its 91inches long. It has good lighting and the disc brakes front and rear stop you on a dime. We also like the thicker seat and bigger gas tank on ours which is why they call it a cruiser. It holds 4.8 gallons so a fill up will get you over 300 miles on a fill up. The trikes are still not broken in I don't think we have under 500miles on them and we are getting I think around 65 miles per gallon at the moment. They are very stable even cranking them up due to their weight which is 353 + Rider. The Reverse works great, but have the time we don't use it cause they roll very easy. It has all the goodies, on the left handgrip you have the emergency park brake, headlight flasher, High and low beam, Turn signal and Horn. On the right handgrip you have the throttle, emgergency cut off and electric start. On the console you have Left to right, Fuel guage, Speedometer, Tach and battery voltage guage. Just below the Instrument panel you have the Turn Signals and an indicator that your lights are on. Built into the Tach you also have a Clock and Date and it also has an Trip Odometer built in the Speedometer. The seat opens Sideways and there is room for tools and small items, but a helmet will not fit under the seat thats why we got Trunks on them. In front by the handlbars you also have a Glove box where you can carry some small items as well.

Registeration was a breeze at our DMV. Here in Illinois you need prove of insurance, MCO and bill of sale (FOR TAXES). We got the "M" Motorcyle license because on the MCO it said it a 150cc if it had said 149.6 we could of gotten the "L" license. We were actually happy we got the "M" License cause now if we want we can ride anything over 150cc. Because its a Trike they do put a restricting on your license that you can only ride something with 3 or more wheels. We had to take a Test which was a breeze, they took out 2 cones because a Trike cannot zig-zag around like a motorcycle. And then a timed stopping test and that was it.

I am mechanical inclined so I can fix things. Ice Bear is Fantastic for ordering parts if they don't have it in stock they will order it from overseas. Also we have found that NOBODY knows anything about the Trikes. The only difference is the Rear End the rest of the Trike is just like any other 2 wheel Scooter. Actually I know more about the Rear End on the Trikes than any Ice Bear or Roketa tech.

The manual like any other Chinese product is pretty useless just your basic information and broken chinese sentences:)

All in all we love the Trikes we get questioned at red lights from people in their cars. One asked if it was Customed Built. I chat with them answer all their questions, Where, What, How Much and how fast they go. They are really a Show Stopper.

Thank You alleyoop, great information. Since my last reply I did call my DMV rep and this trike is legal in Wisconsin and all the proper paper work has been filed with the State. So now I will get the franchise paperwork signed from them and sent to the State and add these to my DMV License as a brand I am legal to sell.

I have worked on Harley and Honda Trikes for years, the first one was a 63 1/2 Harley trike with flat head motor, there goes my age again, so I am familiar with trike axles.


Thanks Again

Friend,

Sounds like you have your trike running about as well as it can. My 150 2-wheeler also experienced the "burp" at high speed as you mentioned. In my case, replacing the complex air-filter system with a simple Uni-sock filter (along with re-jetting the carb) cured that, and gave me a lot more clean rpm. (My Xingyue Eagle tops out at 8,200 rpm, and 53 mph).

I am going to try the Prodigy variator too. You have had good results, and so has JR. The lower rpm combined with better top speed is GREAT. 8,000 rpm+ is no good for the engine.

One other change I made which actually did make a noticeable difference in overall performance was to change out the stock CDI ignitioin box with a high-end "no rev-limiter" unit, and, replace the stock coil with a Bando coil. These changes were not very expensive, and are truly "plug n' play" with only minutes required for installation.

I do love your trike! VERY cool...

Stay safe!

Well just goes to show you what they have done with this body style! You have the 150 two wheel version with the long case GY-6, the 250 version with the 244cc CF Moto clone, the 250 version with the 257cc linhai clone and now the trike with the GY-6 short case!

So when it's all said and done say if someone wrecked a trike and the rear components were all good you could easily convert a two wheel version to a trike! Just wonder when they will come out with the 250 trike version of this body style??

Hey also alleyoop need to check your MPG as it is going to go up now with the Prodigy variator! JRR

[als01seville]

Hi Troops, Just an F.Y.I Ice Bear is coming out with 300cc Trikes next year. They show two pictures one is Touring one like mine and the other like the one Dwild62 has.

Hey Eagle150, I don't know if a CDI will do anything for me now that my max rpms are 6900. On my Trike they say Max HP is 8.5 at 7500Rpms. What I am going to do is add a High Performance Coil and a Iridium Plug. The engine should run smoother and idle better than it already does. Question To Anybody: What Heat Range Plug should I get? If its a NGK or Denso(japanese) The higher the number the Colder they are which is opposite of U.S. U.S is higher the number Hotter it is.

Eagle150, i saw the prodigy on ebay for $65.00 I paid $91.00 shipped.

Hey Jrryan, yes I will have to check the MPG, the engine only has 460KM on it as it breaks in I believe it will get better with age(like me). But I won't be putting on two many miles on it this year, its getting cold around here in illinois and this morning I backed out my car and took the trike to get the Newspaper which is 2 miles away the LONG WAY AROUND:) Any exuse to Ride.
Alleyoop

[JR]

Oh it's going to get better MPG for sure and also want to say that if you are hitting 6900 RPM but the max power curve is at 75k then you may want to consider dropping back to 11g weights. The rule of thmb is 500 rpm increase for every gram you reduce so this might put you at the max power curve but still hold the engine way below the 8k mark and give you your maximum HP at WOT! Just a thought!

A 300 trike now that sounds sweet, wonder if it's going to be the 300 linhai? If so and it's like the present 300 that is listed it will actually be only 275cc witha 72.5mm piston. Wish they would hurry up! JRR

[als01seville]

Yea but going lower will drop my top end some and I don't want to mess that up. I might give your other idea a try about shortening the Variator Sleeve about a 1/16. But I would want to order a new one just in case it doesn't work or messes it up. You can't glue back metal:) Do you know were I can order one?

I heard ICE BEAR was bringing out a 250cc & 300cc trike for 2010. I know Roketa has a 250cc trike right now 2009, I seen it some where. Roketa trike models are MT150-9, MT150-11, MT150-H, & MT50S-8 (50cc).. I can't remember where or who was selling the 250cc, but I believe 2 of the 3 models offered both the 150 & 250cc trike. Well I see those 4 models, I'm not sure what company they belong to.. Here's the roketa models MC-101-150, MC-102-150, MC-104-150.. Still can't find the 250cc, but I know I seen it.. I see ICE BEAR also has the PST50S-8 (50cc) trike..

[als01seville]

They are showing a PST300-1 which is like yours and a PST300-2 which is like mine.
Hope so if they do I may sell mine and get a 300:)

[als01seville]

Hi Dwild62, Roketa is showing only 150cc Trikes, MC-101,MC-102(like yours), MC-103 and MC-104(like mine). This Trikes are the sameo, sameo from Ice Bear no difference. Except if you notice on some from different dealers they show little differences. Like for example some do NOT have the Rear Cover to hid the Axle. Some just have the Fenders and a Center piece much larger than were you and I have the lighted plate mount. So I don't know how they order them maybe to be different or what but I have noticed that looking at their pictures showing the rear of the Trike. I like our center cover which covers the entire rear Axle.

Well, I know I saw the 250cc some where, because I seen it when I ordered mine. My previous scooter purchase wasn't very good, so I was only willing to buy from a company w/ a good score, which was Scooter Dynasty. Also I wasn't interested in a 250cc, because I wanted to stick w/ air cool. Didn't want to mess w/ anti freeze, radiators, coolant hoses, leaks, ect. Was looking for fuel economy, figure I didn't need another motorcycle. But I like this thing so much I could change my mind & buy the 250cc next year and give this one to my wife, & sell the 2 2 wheel scoots..

[JR]

Alleyoop yes the norm is a top end drop when you reduce the weights but I went from playing with 14g all the way to 12g and in between and with the larger OD I didn't lose any top end! But I did raise the rpm's a little which helped me on the hills and the lower weights helped on the mid range speed!

I don't know if you can just buy the shaft but if it can be bought seperately this guy will know or will get it for you! Great guy and his name is Mike;
www.buggypartsnw.com/

He always has free shipping under 10 lbs so give him a call and if it can be done Mike will do it!

Some good looking trikes here but no 250cc??

[als01seville]

Hi Jrryan, I logged onto buggyparts and he has great prices. A NGK Iridium CR7HIX Plug 9.95, a NGK Performance Coil 34.95. His site is getting security renewal and I got Security Errors and i emailed him. He thanked me for finding the bug and is giving me $5.00 off on my purchase. I ordered Two CR7HIX plugs and one performance coil. I also asked him about the Variator Bushings and he cannot get them seperate they come with a Variator&Fan Package. I mentioned to him about milling off about 1/16 on the Bushing and he said that I would loose low end Torque since now the belt would be riding higher. I also asked him about a bushing I saw that has the OD smaller were the belt sits and he said he dosen't know were to get them either. So thats were I stand right now. But thanks Jrryan he has very good prices other sites I checked the cheapest I found for the PLUG was 13.95 for a plug PLUS $10.00 to ship and the coil was almost $50.00.

I'm using the standard NGK spark plug, side gapped. I read a performance article, that stated a side gapped spark plug tends to be better in the sense that they hold up better, cheaper, & has the same affect. People used this method before these expensive performance plugs were introduced..

[JR]

www.ngksparkplugs.com/tech_support/spark_plugs/faqs/faqpregap.asp?mode=nml

OK guys here is some valuable info about spark plugs especially the NGK. You can read a lot about the whole plug theory on their site.

Like a lot of folks I run the Iridium and have done a lot of road tests, and I mean a lot such as open road, city, different heats etc. and the general conception is Iridium always better and by all my tests the conclusion I came to is you just don't have to change as often so if you can shop around like Alleyoop then they're OK!

Now you have also heard don't set the gap on an Iridium but even NGK says that is not always true! For instance I own two linhais and on my 250B the Iridium version most used is the DPR8EIX-9 and it runs great as is on my 250A but on the 250B it did not idle well and didn't start as well so I closed the gap from .036 to .032 and all was well!

Sometimes depending on certain factors one can change the heat and I went to a DPR7EIX-9, gapped at .032 and she runs better, starts better and improved MPG by 2 so that is just an example of how things can differ! I run the plug you mentioned Alley in my 150.

On the variator shaft that would for sure have an effect on the low end torque but only a test would know how much??? If ya didn't like it you could always get some round shims and put it back easier than cutting it down?? In fact I think the Dr. Pulley racing variator comes with spacer shims??

I did do it to my 150 and the belt is at the outermost OD which actually gave me all the top end I could get while reducing the rpm's by another 200 or so! Like anything it all depends on what ya want! I went from the 70 to 72 mpg mark to always 80+ MPG with my changes so the variator will pay for itself! JRR

[als01seville]

Hi Jrryan, I am not so much interested in the MPG, heck it already gets at least 65 mpg, and i am sure once the motor gets more miles it will get even better. You say you did it to your 150
and your belt is at the outermost OD. WHAT did you do to accomplish that, the HOW and WHAT I lost it somewhere.
Alleyoop

[JR]

Like I said the Dr. Pulley variator kit as you can see comes with the center shaft whereas the Prodigy didn't so you had to use the one from your old variator. I took my shaft and had it shortened by about 1/16" which did the trick! If you don't like it just put spacer washers or shims back and put the length back to it's original length! Like I said you can get you some shims at the above link if you need them!

I only mentioned the MPG and yes it is going to do better after break in but also remember an engine that can go 50+ MPH at 7k RPM is going to get better MPG than one that does the same MPH at 8k it's just common sense! JRR

[als01seville]

Hi Jrryan, What did you gain picking up the 1/8 that was left on your Variator after shorting the bushing 1/16. And what size shims if you know.
Thanks
Alleyoop

[JR]

I gained about 2 MPH and about another 100 rpm drop and to me it felt like my take off was stronger!

I did not need the bushings as I left it shortened, they are only needed if you don't like it and want to go back to the original shaft length. You will need to measure the shaft ID and OD to know what size you need and of course the thickness in case you take some off of the shaft! JRR

[als01seville]

Thats sounds perfect, But hey Jrryan you got me to buy the Racing Variator off Ebay, I thought you had that one on. Now your telling me you have the Dr. Pulley!! Are you telling me now to go and buy the Dr. Pulley Variator which comes with the shorter bushing!!
Alleyoop

[als01seville]

Jrryan, Now i am hearing that the Dr. Pulley Pin is NOT SHORTER. Do you know the lengths of the orginal and the Dr. Pulley Pin length.
