Modern Vespa

Hey all,
I just bought this 200L and it's my first Vespa, I have worked on others before but 1st time with a Vespa. I bought it used so naturally needed to change the rollers and belt since it had about 9,000mi. on them. Well needless to say I followed the 200GT wiki guide (which was very helpful) and also consulted the workshop guide in doing this but something doesn't sound right after I put it back together. Took it for a run and as far as I can tell feels normal but when at idle and not moving you can hear the variator make a slight clunking noise almost as if it was misfiring. Not sure what to make of it and the noise definitely sounds like it's coming from the variator.

Any help you guys can give I really appreciate!

Are you sure you installed the rollers correctly? IIRC they should be fitted with the bare metal sides facing 'left' or counterclockwise.

Is it a deep, solid clunk, or a light clacking noise? Clacking from the variator is normal when at idle or coasting to a stop.

Also, how bad were your old rollers? If they wear too far, they can damage the variator itself.

Well I followed the pattern of the old rollers, I put the new one's in exactly the same way I took the old out. If they were not counter clockwise, the noise was not an issue prior but I will take it off again to double check.

Pretty solid clunk...The old rollers were actually in good shape but wanted to replace them since I had gone that far.
Also, when the noise happens, you can feel a vibration throughout the scooter.

Hmm.. At idle, the variator should just be spinning freely (with no clutch engagement in the rear). It shouldn't be something you feel. If you're absolutely certain that it is a result of the belt and roller change, I'd open it back up and double check the install. If something in that area is making contact with another part that it shouldn't, it will be pretty obvious. If something isn't meshing properly in there, you could screw up the splines on the shaft, which means new crankshaft! Not a fun job..

Ok. One other thing, in the wiki guide, he had that belt pressed pretty far down in the pulley, I was not able to force it very far in but it's in. Would that have anything to do with it?
