Marcia, WOW!! I did not have any idea, I sure missed the posting back in July. Here I am thinking you are cruiseing around enjoying the sunshine and warm breeze. Well I sure hope you heal completely and will be able to ride again. As far as the Trike, maybe your husband can take it for a ride up and down the street to charge up the battery and not allow the gas to get gummed up in the Carb. But if not you should start it up and let it warm up at least once every couple of weeks to keep the gas flowing through the carb and charge up the battery. Again Sorry to hear you cannot ride but hope you heal fast and get better. Alleyoop

The way you say it acts when giving it gas and then backing off the throttle a little and it peps up, you are running LEAN. Try giving the air/fuel mixture 1/4 turn Counter Clockwise, try it if it gets better give it another 1/4 turn and see if you can get rid of the boging.
When you adjusted the valves was the Piston at Top Dead Center with the two little holes on each side of the Cam Sprocket even with the Top of the Head and the bigger hole in the Sprocket straight up. Alleyoop

Yes it could be something silly, like when you forgot to reattach the ground wire to the Valve cover. Maybe when you had your hands in there you pulled a Vacuum line off, check all the Vacuum lines. From what you said you adjusted your valved correctly and now it does not die when you stop. But now it appears something else is causeing fuel starvation. Alleyoop

I tried to read through your descriptions and come up with some ideas that fit your trikes symptoms.
First some simple facts. A vacuum is created from the movement of air in your intake (the rubber piece between your carburetor and engine has a nipple with a hose attached, the vacuum is created there and is used for various functions with the engine.
The positive air pressure you mentioned blowing from a tube must be created by the engine, probably your PAIR system if you have one, or more likely the valve cover vent.
Rerouting hoses is not advisable, they can get real confusing real quick.
A lean fuel condition is evident by surging at mid to full throttle settings.
A rich fuel condition is evident by backfiring ( bang noise) and stalling after coming to a stop. ( you already did the valves which also causes stalling so we can eliminate them)
All of these conditions I have experienced and remedied my self on my scooters. So here is what I think you have going on.
Possibly some hoses are hooked up wrong. You will have to do your best to get them back to factory specs for now.
However if it is sucking air it should be hooked it up to either a fuel pump, petcock valve, or your vacuum lines. When you unplugged the line sucking air you leaned out your mixture and thus your RPM increased since you were probably running rich before hand.
The other line blowing air should run to your air filter box. There probably is a nipple on the bottom of it or some where to attach the hose. It however should be the least of your issues, hu-ray!
Finally turn in your air / fuel mixture gently all the way and then back out 2 and 1/2 turns. It is located on the bottom of the carburetor.
Find your idle screw, probably on top of the carburetor near the throttle cable and start the engine and set the idle to 1700 RPM, or a nice smooth slow speed.
Test ride it and turn the air / fuel mixture in 1/4 turn if it still back fires. These little engines run fine lean, so don't worry. After you get the idle and mid range worked out hopefully the top end will be ok. I usually work on high speed first, but that technique is way to complicated to describe here.
Tackle one issue at a time. Put your lines back to the way they were when it was running good, then adjust the carburetor, and check for loose clamps on the carb and intake.
Best of luck I will check back later to see if you have any questions.

Thanks guys, If I get time I'll work on it some tomorrow, but I have classes most of the day, so we'll see. If not I'll work on it Thursday AM before night classes. I'll double check the vac. lines Alley I pray it's something that silly. well on the bright side I've gotten a good tan today

If a compamy has no technical manual for their products you better run--they are only in business for the short run---grab the fools money and run. I really have to disagree with this statement. There are lots of companies that do not have their own technical manuals for their products and have been in business for a long time. Take Roketa for example, they were established in Ca in 1999 and have become #2 or #3 in the US for sales of chinese machines. They don't offer repair manuals. There are many other companies that have been around a long time and do not offer manuals. I only speak of Roketa because I know this company first hand. One of the main reasons why the Chinese Industry does not offer manuals is that translating Chinese terminology to American terminology is not an easy chore. There are to many differences in what they call things. For example a turn signal flasher is called a singing relay. Now I have been told by IB that there is service manuals in the works for their trikes, however it is a long process and I was told not to expect anything till next year. Jim/Owner Rapid Repair

Jim if i read this right:
Quote "I had a hell of a time getting the valve cover off, it was cracked on the left top bolt, and fell off on that side when I got the others off."
if a corner of the valve cover is broken could there be a vacuum leak there?? It says the cover fell off with the other bolts off.

No that wouldn't cause a vacuum leak. One heck of an oil leak yes. Basically, Vacuum is created inside the combusion chamber from the piston going up and down and the valves opening and closing.

When putting the valve covers they should should be nice and snuge but not to tight the head is aluminum and the threads can be stripped inside the head. The valve cover has a rubber washer going all around it in a grove and that is what keeps them from leaking out any oil from the bottom. Alleyoop

Wingcommander, FANTASTIC!!! That hose that was curled is connected to the INTAKE which is the important one . That is the one that has suction to work the diapghrams in the Fuel Pump to pump the fuel up to the Carb and also for the Deceleration Hose that is the one going over the carb. Is your idle at least 1500, if its bogging on you a little that would be your air/fuel mixture needs a little more adjusting. But when you turn the air/fuel mixture just turn it 1/4 at a time CLOCKWISE Lean it out a little and then try it. The hard starting could be your ENRICHER(CHOKE), but it also could be caused because your running rich and the extra fuel when cold is flooding it out a little. So first get the BOG out of the way and that also will probably fix the hard Cold starts. You are almost there, just some little twiks. I would also connect the Hose that you cut to the MIddle of the "T" and have the other two hoses connected to either side. In other words SWAP the TWO Blue hoses and twist the "T" to point to the intake that way both sides will get the suction evenly. Also cut the hose so that it is almost straight connected to the "T" with no loop on the hose, that will give good suction to the other two hoses. Alleyoop

Running better, it's leaking oil a little bit but I think it's like Jim said from the valve cover (their supposed to be sending me another one) So hopefully when I get that it'll be AOK Going to drive it on a road trip tomorrow (taking a quart of oil with me) So I'll report back after that!

Trike did pretty good, cept for a few things. It's leaking more oil and I'm really hoping that's just coming from the valve cover being broken (we'll see I suppose) &&& the MAJOR ISSUE Was not the trikes fault. I took it to the shop on Friday cause I wanted everything looked over good just to be on the safe side, Was still having a slight issue with the trike stumbling when I hit the throttle sometimes, but after the mechanic adjusted the carb Trike was running AMAZING no backfiring, no stalling, (leaking oil a bit) but nothing major. It was enough to make me say "Ok I can go to my Grannys!" So I did. All was good on the way, trike did die on one red light but I gotta give it props it went up and down some hills on a road that I wasn't aware of having to go over and did ok (35mph) but still TRIKE DOES NOT LIKE ANY KIND OF HILL sooooo started home that's when the trouble started. Died at a red light managed to limp to a nearby walgreens and then the bear wouldn't start. Checked a few things after it got good and cooled off (I thought at first it had overheated) Then looked it over better and realized that my air hose had fell off, thought hey no big deal , be on the road soon . . . . WELL when further inspection happen, found out that the mechanic had unscrewed the air / fuel screw so much that it fell out (must'a been at the red light) and it would start but not stay running. Went into walgreens and bought a pack of all purpose screws thought I might find one . . . No go. So I put a long thin screw in the hole, and rigged up a cable tie brace for it (cable ties and duck tape will save the world) To hold onto the screw so at least the hole was plugged, and boom she cranked right up!!!!!!!!!!!! on a wing and prayer we drove another 90 miles to get home. So now, I have a trike leaking oil, no air fuel screw & its slowed down to about 45mph lol However, it's never ran better lol go figure???

& I say loving it again, because it must be a pretty good machine to be able to come another 90 miles with a major boo boo (unless the oil leak turns out to be something more I do love my trike)

So I'm twiddling my thumbs waiting on my parts (valve cover / new air /fuel screw) so I decided to take my back fenders off, a kid jumped on them at a shopping mall and cracked around a few of the screws, well since my road trip I've noticed a few more cracks on another screw, so I"m jbwelding it from underneath to give it more stability, and trying to figure out anything else to keep the cracking from getting worse. Also I took my seat off, and am in the process of putting more padding on it, + getting LED Bulbs for the tail lights. This is what happens when I can't ride

So I had to go out of town and didn't get to send off my parts until yesterday. Was told I would be getting a whole new carb. Which I hope it helps cause right now the take off speed is kinda slow. The oil leak did stop so I think the valve cover wasn't the issue but I didn't have it screwed in all the way Still trying to backfire a bit, but I'm pretty sure the new carb will fix that. If not back to sq. 1. All in all I'm very impressed with the trike. 1 thing to note. The seat is not waterproof!! I forgot to put my cover on one night when it was raining and got a wet butt So everyone be mindful of that

wingcommander, i really really like the way you fix your seat, but,honestly i find the trunk very bulky,it just doeasn't match your beatiful scooter. ..for 80 bucks you can find a nice ,decent mc trunk brand new., but overall your trike looks awsome...just put a little fashion on the trunk. just a frendly opinion,no offense meant.
..And hey,btw where is Als01seville?? his last post was dated oct 21 2010??,,we must admit, that guy is very mechanically smart,...and he has help a LOT of scooterist here in SD...wonder what happened to him??anyway,his expertise is definitely needed here,let's hope he comes back....imo

Luke I'll agree it is very bulky but what I like about it is this: I can fit lots of stuff in, more then a MC trunk. And I use my scooter for practical around town errands and to go to school. So for me the bulkyness was ok. But I do agree it's not "pretty" I did add a "Failure is not an option" bumper sticker to it I thought it was appropriate for a scooter hehe I don't know what happen to Als01seville either. I PM'd him but no response. Jim says he's on the other board so I"ll look for him to he has been a MAJOR help with my trike and I wouldn't have felt ok to buy one without his and Jim's help and guidance.

Ok after waiting FOREVER for my "new" carb, I got sent a used one from superiorpowersports.com that leaked so much gas in the USPS box that when I opened it, I got soaked after I unwrapped it from the plastic. And what was missing in my box??? My new valve cover. . . Called and they said I never asked for that I'm done dealing with them, it's crazy. So my final review. . . I WISH I had bought from RapidJim and NOT superiorpowersports.com I know some people haven"t had any issues but let me tell you if your one of the "lucky" one's that do have issues they are a joke with tech. And they don't even sell the 150 trikes now or the 300's So now my trike is still leaking oil, although it dosen't appear to be coming from the valve cover, and I'm not sure the "NEW" carb will help anything. . . guess I'll find out soon.

There's no oil in the carb, so it'd be very surprising if it did anything. Have you checked the base gasket or timing chain tensioner?

Post by wingcommander on Dec 24, 2010 13:56:38 GMT -5
The oil in the carb wasn't the issue the trike is just leaking oil like crazy. The carb issue was the air/fuel screw blew out the side when I was riding, and before that I was having major issues with the carb alone. So they were supposed to send me a new one. When I went out today I found it' was prob. a 50cc carb they sent me. :sigh:
base gasket or timing chain tensioner? how would I check those? I'm still new to fixing major things so any advice would be welcome.
Merry Christmas everyone!

Sorry, I should have been clearer. I was trying to say that there was no possibility that replacing the carb would fix any of your oil leakage problems.
I believe that the engine is your standard 150cc GY6, correct me if I am wrong.
You need to remove the black engine cooling shroud to investigate further, if you are lucky it will be obvious where the oil is coming from.

So after finally saving enough to take the trike to a shop to finally get it 100% looked over my doggie got sick and had to have major surgery So the bear went away yesterday On a bright note my dog Princess (in the photo under my name) is doing much better and as long as no infection sets in should be good! I already miss my trike, and when I go out to my parking spot I first think someone stole it lol then I realize
