Scoot came to a complete stop?? By cwillard (Read 756 times)

[cwillard]

First of all thanks for all the great info, I have learned a lot from just reading all posts and tech help. Have had a Tao Tao for about 10 mths now, and have a few small issues that have tackled by myself. Fathers drive drive belt broke on way to work, got home took apart CVT, had a hard time getting Variator off, but got there, cleaned up placed rollers back in, installed belt( couldnt get clutch bell off) and was up and running, 4 days later scoot bogged down, and quit on me. Now I can almost turn over getting compression from engine?? Any ideas could it be garbage in clutch that wasnt cleaned out. Or would it atleast turn over? Visual inspection inside CVT everything looks good??

What do you mean when you say
"Now I can almost turn over getting compression from engine?"
Are you saying the motor will not turn over 360 degress JUST 180 degress and it stops?

The clutch disengages when the RPMs drop below a certain point so if your engine is off it's not connected to the drive train. If it won't turn over the most likely suspect would be a low battery, charge it up and see what it does. It is very rare but sometimes a clutch will fail in the engaged position. Just to make sure that didn't happen try to push the bike, if it will roll it's the engine. Rich

Im still learning, but what I meant was it seems to turn over, but wont engage, when it stop runnong engine was still running but I just stopped moving (similar to belt snapping) Is their a way to test what you are asking?

I drained battery seeing if It would turn over, and I have since recharged it, scoot does roll, (was able to load on trailer to get home) is their an order of which I should start to troubleshoot repair?

Yep, put the bike on the centerstand and remove the CVT cover. Start it up and give it a few RPMs. If the belt is turning the rear pulley but the clutch bell isn't turning it's the clutch. If so, you'll have to get an impact and strap wrench and remove the clutch so we can figure out what is wrong. Rich

Thanks, and is their a place I can get a "strap" wrench?

Harbor Freight, Autozone,any auto supply place. But you need an impact wrench as well and a set of impact sockets in metric

I never needed a strap wrench to take off clutch or variator, Just your hand and a decent impact works. I have taken off 50cc, 150cc and 400cc variators with my impact. As I remember I paid $15 or some thing like that at a pawn shop for a 1/2" air impact. My compressor has about 90lbs is all. With out an impact you will damage some thing. Read back in the threads about broken fins etc. A impact is way less likely to strip threads on a rusted bolt too. Impact sockets are better, but a decent socket will work in a pinch. Its just that regular sockets won't hold up for daily use if you were making a living with them. john
