This is a tough one

It seems like the problem was in the variator all the rollers were worn some more than others one of them was so bad it was getting stuck on the ramp plate and jamming it all up so it couldnt move.

I have 3 clutches and 1 of them for sure eats belts its almost impossible to open. another i think might work but it doesnt feel right like it will open straight backwards and close right away but i see a washer or a ring of some type loose in there riding the axle or whatever. And the one thats on there now opens sort of easily and rotates somewhat while it opens but i think it gets stuck open so maybe i just need to replace the springs?

I was thinking about checking the variator but i didnt want to disturb anything if i didnt have to. the last time i looked in there when i changed the belt the rollers were a little worn that wasnt too long ago ill check again though. Maybe I need heavier or newer weights?

Ive been having acceleration issues lately and think it might have something to do with the clutch. It only happens when I try to accelerate from a dead stop. I could go WOT and and it just starts going really slowly for a few seconds or so and then its back up to regular speed. I checked the valve gaps and they were fine. I was thinking maybe fuel starvation? and then I thought maybe variator or clutch when i looked at the belt i noticed it was kind of in the clutch not really riding near the top. Is that how it is supposed to be? I took these pictures while it was idling.   |

As long as compression stays at or below 200 psi I dont think ill have too many starting problems its definitely worse when its colder out. I upgraded my battery cables to 8-awg and switched to 5w40 synthetic that along with spring and summer temps in the near future I think ill be fine for a while anyway.

Im thinking of just getting a high performance high torque starter

check the battery maybe have it load tested at an auto parts store or somewhere and check the fuse if you havent already

I checked the carb and everything seemed fine. The fuel petcock was suspect so i replaced it with an inline manual fuel valve shutoff. I did get the scooter to start and the oil was full of gas so i changed it to 5w40 synthetic. I also replaced the battery cables with 8awg. But I was still having starting problems. I even tried jumping it with jumper cables directly from the starter to the battery and nothing it wouldnt even turn over. So I took the fan cover off and rotated the fan/flywheel by hand it was difficult but i could tell there were times when the valves opened there was less compression and that is the sweet spot for starting. if it gets stuck on the compression at tdc or whatever when the valves are closed the starter cant do anything so i have to rotate the flywheel by hand to get it unstuck to where the valves will open so there is less compression and then it will start.

I had a problem similar to yours and it ended up being a problem with the stator. Im not saying thats your problem just throwing it out there that it could be. It helps if you have spare parts that you could swap to test it out.

I think i forgot a 0 in there does .004 sound better lol Im pretty sure the gas was leaking out of the exhaust as I was trying to start it it started coming out of the muffler mostly where it connects to the header pipe and a little out of the end. Maybe I just need a bigger ground wire then. My scooter uses a totally dc system with a floated ground. I have a small wire connected diretly from a bolt on the starter to the neg- post on the battery not sure what gauge but its closer to the size of most of the wires on the scooter not the 2 big red and black ones that connect directly to the battery.

The gas leak problem is a recent issue and I think all of my recent problems are compression related. It definitely seems to be the hardest to start when the temperature is the coldest. And right now heading into spring or as i like to call it (sprinter) spring/winter the temperatures can vary widely here around chicago from below freezing to 60's almost 70's right now were averaging a high of 50 to a low of 30 but it could definitely get colder or warmer than that I thought I was still breaking the bbk in but with a compression of 180 im not sure what weight oil to use. besides being difficult to start i think the high compression was opening up my valve gaps. I noticed when I would slow down for a stop light or stop sign the scooter was starting to die at first i thought i was being fuel starved because of a bad petcock because it didnt look like there was any fuel in the filter. so i bypassed the petcock for a little bit but was still having the same problem so then i checked the valve gaps and they were a lot wider than i usually set them so i adjusted them back to normal .04 ish maybe .03 - .04 for intake and .04 - .05 for exhaust then i reconnected the petcock and sucked on the vacuum to it to prime the filter could i have damaged it doing this to cause my gas leak? and then when i went to try and start my scooter with the cold temps, high compression and possibly faulty petcock i think thats what lead me to all my problems now. So im looking at getting better battery cables do i need to upgrade the negative ground wire too or just the positive? and maybe getting a manual petcock. And then maybe switching oil weight but im not sure if i should try a 10w 5w or 0w. Thanks everybody for all the help I really appreciate it. Im going nuts here trying to figure all this crap out.

Arent jumper cables kind of a little too thick to be using for battery wires? What gauge wires should i be using? And the gas was mostly leaking out right between the muffler and the header pipe there was actually a small puddle starting to form on the ground and then i seen some wetness coming out of the very end of the muffler and when i did my compression test the tester had fuel in it when i hit the release a mist of fuel shot out and it was leaking out of the tester hose too also when i was checking for spark some mist of fuel shot out of the spark plug hole. How about switching from 15w40 conventional to 5w40 synthetic would that help at all? and is doubling up on the cylinder gasket the best idea or should i look at getting a higher performance starter? would i also need a high performance starter clutch?

yeah but the flooding didnt happen until I tried to start the scooter the more i cranked it the more fuel was coming out im thinking compression is too high for my starter and ill need a better one?

My scooter wouldnt start at all today I think I might need a better starter? I did a bbk install recently and my compression is 180 psi. My battery is almost brand new fully charged and hardly ever used it. after trying to start it over and over i think i might have flooded it and fouled the plug gas was leaking out of my muffler. I also confirmed I get spark but still no start.
