engine rebuild

[dingman29]

i was thinking about checking out the gears in my engine while its out and figured i should rebuild it while its apart. the only problem is finding all of the bearings. everything on ebay is very expensive. soes anyone know of an aftermarket source thanks

Crank bearings are still available from Yamaha.. but if you don't like Ebay prices... you're SOL.. lol. My local shop has them for $12.50 a piece.. times 9. Then the saddle bearing is a bit more.

Rod bearings are unobtainium and Ebay is going to be your only choice for that.
