gear change on autos

i would surpose you could just replace the part with the grooves if the other side is not knackerd.

but ive only seen them sold in halfs if its a polini or malossi pully and they are around 90 euros

after having a look on scooter center they are saying the pully is the same as the 50cc version so it should be easy to find a complete unit cheap on ebay

 

ordered a new outer pulley today for £66, it the same as some of the 50cc pulleys. At some point yamaha moved from one size to another so its not as easy as just any old 50 pulley sadly, otherwise it would have been much cheaper!
