Does anyone know how to disassemble the rear pulley on an eton viper. I am able to take the
pulley assembly off the bike and remove the clutch, but then I have no idea how to get the pulleys
halves apart. Thanks in advance for your help

 

pull the sleeve off the pulley. This is the piece that the pulley spring sat against.
Remove the two pins from the ramp grooves
slide the two pieces apart.

switch seals and o-rings

Re-grease and re-install.

How do you get that sleave off?

 

hold the pulley in one hand, grab the sleeve in the other while you pull and twist it.

 

I'll give it a try and let you know. Thanks for the info.

 

You were right. The sleave just slipped right off. Peace of cake after that. Only one
problem. The Polini pulley half I ordered is the wrong size. Just a little bit too big. The
sleave won't fit back over it and when assembled it is kinda loose. Any ideas?

 

That is the problem with either trying to go direct to a scooter company to buy your parts or going to a "ATV" shop that should not be in the business of selling parts for these minis.
