Dwild62, Well I believe I found what is and or what causes the problem with the low rpms. I check out the Variator and IF the belt is pushed out all the way which means the center of the Variators are touching at least one Slider and or Roller will come out of the bin and lay there either on its side or gets hung up on its edge. So what does that mean, it means the Rollers or SLiders have to a bit bigger in diameter to stay in the bin and not jump out. So since we always get 18X14 is there a slightly bigger Roller or is Slider in diameter that would work? Alleyoop

Hi Dwild62, Hope everything is ok with you and you are well.
Well last night I put in the Prodigy Variator but first I hit the hole with some sandpaper and smooth out some burrs it had causing it to bind putting it on and taking it off. I put in 12G Sliders and the OEM 115mm Variator Fan for more cooling. Rode about 20 mile today testing it out and it is running like a CHAMP. Rpms go up to 7500 rpms at 55mph. It has good pull and pickup and Gets to 45 pretty quick. So I am right on the max power band. When the new belts arrive and put one on I think I will put in 3-12G Sliders and 3-13G sliders for a combo of 12.5 and get it to around 7200-7300 or so and see if I like it there if not I will change back to all 12G Sliders. And the CVT is MUCH cooler probably due to the bigger fins on the OEM Variator fan. Alleyoop

Well Dawg's I put in an all nighter, tore the rear end of my BEAR apart.. When you get on the throttle to hard when taking off, the rear would jump.. Made 2 shims for spider gears in the differential unit... David Sr.

Dwild62, So did you find that there was a lot of slope in the meshing of the gears. Did the shims help. Hey that muffler might do the trick but I bet its a loud sucker:) Heck with that bracket already on the muffler it would be easy to make another bracket to fit the muffler bracket. And keep the other one in case you have to mount the orginal back on. Alleyoop Alleyoop

Alleyoop Ya, I think it might fix the problem, a few miles will tell.. I did 1 test run, & I couldn't make it jump.. I think .015" shim would be better, .020" shim just a tad tight.. I made an extra .020" shim, & a .030" formed shim for the floating spider gears, I'll take those to a local machine shop & see how many $ & if they can make & a few of both out of different shim stock, .005", .010", .015", .020"..

JRR Well, I haven't figured out how to be in my shop & work on the scoot, & play on the computer in the house, all at the same time.. I have a 25" TV in my shop so, I guess maybe I'll have to move my computer out there to..
Man I've got to stop doing all nighters, I'm getting to old for all that..

If you need A float height guage & can't afford one, or you're just cheap like me, or you're not real handy to make a fancy one, you can make one like the one in the pic below, from non corrugated card board, or a piece of plastic from a coffee can lid, or something similar.. This is the type that came in carburetor rebuild kits years ago (60's, 70's, 80's), & they do the job quite well.. This is what I've used up until I made the adjustable aluminum one above.. David Sr.

Jrr I ordered a #38 pilot jet tonight. But here's the kicker, Keihin doesn't list a 33mm long pilot jet, the longest they list is a 28mm, which is about .375" short, but I believe it will work... Next week I'll get those mini drill bits..

The short one will work fine! Yes back in those days companies helped folks with little things like the paper gauges and such, not any more! Heck I can remember when if ya smoked a lot of stores would just give ya a little packet of matches! Remember the old go-fer matches? Strike one and go fer another one! LOL That was also when a penny would actually buy something too! Man that was a long time ago!! JRR

Alleyoop & Jrr Ya, I'm old enough to remember those days.. Now, I even remember when you could buy a gallon of gas for $.50, but I dare to say, you OLD FELLER ;D ;D, are just a little older then me, so you probably remember gas even cheaper then that.. When I started smoking, a pack of smokes were only $.75 / pack, & yes you could still get a free book of matches, in some places..

50 cents!! Ha! I can remember when I was a kid and we would go to my grand mothers house on Sunday Dad would always say I'm going to wait until we get to Texarkana to get gas because for whatever reason it was always cheaper by a lot there! I can remember the old Sinclair station ya know the one with the big green dinosaur getting gas for 17 cents a gallon! Full service too, check the oil and tires, clean the windsheild! Remember other things too;
3 cent post card 5 cent soda pop 1 cent = two pieces of gum 35 cent BIG hamburger 10 cent school lunch Montgomery Wards Western Auto Otasco NO WALMART Pledge of Alligance at school Prayer at school
Respect as in Yes Sir, No Maam and just a simple Thank you! Times past! A long time ago! JRR

Dwild62, Hey Bud, how is it going, haven't heard from you lately. Are you having problems due to some of the changes you made. Or are you taking a break and clearing out the spider webs and having a brew. Hope all is well with you and don't work so hard.
Here in the Suburb of Chicago its been raining for the last two days and its going to rain all day tomorrow as well. But the powerlink belts arrived today and I will put one on change out the OEM Variator Fan and put back the Prodigay Variator Fan. I will NOT TOUCH the Variator and leave the 12g SLiders since they have been working great with the RPMs going to 7500. I will mark the Variator and see how far the belt reachs and see what my top speed is with the new belt and the OEM boss. Alleyoop

Alleyoop Well, I'm kinda waiting on the #38 pilot jet.. The bear won't cold idle w/ out throttle, which doesn't make a whole lot of sense, because it did cold idle before I mess w/ the main jet.. The #38 should do it though.. It starts w/ throttle & idle after it warms for a minute..

Dwild62, Great to hear from you and that your ok and didn't go off the rode or something with that BLUE STREAK making turns on TWO WHEELS:) Well with all the things we have been doing I think the trikes will not reach 60mph unless gearing is changed or a bigger sprocket can be found to put on the drive shaft. But I will be happy with consistent 55mph capabilities at around 7200 rpms. Alleyoop

Well, I'm kinda lost here.. As I stated back in this thread, I custom built a 38mm Stainless Steel Velocity Stack w/ a 44mm 2 stage air filter, because the original air filter canister fell apart. I also replace the head w/ a new complete head minus cam, because of striped spark plug threads.. The bear was cold starting & cold idling good. But after installing the 44mm 2 stage air filter, I discovered it wouldn't go, wouldn't rev up, so I started changing the main jet.. I started w/ #120, wouldn't rev up, then went to #122, would then rev up better, but not good enough, so I went to #125, that was pretty good & would cold start & cold idle w/ out throttle, but still no spark plug color, so I went to #128, would still rev up but didn't run quite as smooth, & smelled a little rich, but still no spark plug color, so I went up to #130, would still rev up but didn't run quite as smooth, & smelled even a little rich yet, but still no spark plug color, but at this point it would still cold start w/ out the throttle, & would idle fine. But because it smelled rich & the opinion of other here in the forum I decided to go back & try the #120 jet again, this time it would rev up & go down the road, but then it wouldn't cold start w/ out the throttle, & no wouldn't idle w/ out the throttle until it warmed up.. So I changed the pilot jet to #38, still will not cold start & idle w/ out the throttle, so I drilled the #38 jet step by step, check the cold start & cold idle each time, all the way up to a #55 jet, w/ no change in the cold start & idle, but at that point pilot jet was way to rich to start & run. So I'm back to the #35 pilot jet & #120 main jet.. I've tested the enricher & seems to work.. I took the enricher off & made plate to put in place of the enricher, & I get the same result, acts like it's not choking (getting enough gas like choke), I put my hand over the mouth of carb, it'll fire up.. Any Iders??

BUMMER! well since it fires up with your hand of the mouth you know its not getting enough fuel. So its got to be something to do with the jets you changed that even the little bit of gas the enricher lets in is not enough gas to get it to fire. Alleyoop
By the way David Sr. gave you a bone you most certainly deserve it, thank you. If you haven't read my thread MY TRIKE is running awesome, WOT 7200rpms top speed 55mph.

Dwild62, I read someplace that on 4 strokes, the color of the plug does not follow the old run wot cut engine and check plug anymore. So you could be just fine, just a thought. If your running very lean you will know it at wot it will start to stumble on you or brup at you. Alleyoop

Dwild62, the other thing you might want to try which would be easy is cover up part of the air filter, it may be your getting TOO much air. Alleyoop

WOW!!! The original main jet didn't have any markings on it, so I ASSUMED it had a #105 or #108, but man that's not even close.. Today I found a set of mini drill bits (#61 - #80) at my local hardware store, the only set they had, I'm not even sure that they knew they had them.. So any how I just decided to use the drill bits to measure the original main jet, & it appears that it is #90 main (#65 drill bit), at least according to the chart I've got.. So I'm going to try the, I don't know, maybe a #110? I don't know, see what happens I guess.. David Sr.
