I recently bought a '00 WR400 that will be needing a new piston/rings/rod/bearings.
(the cylinder looks ok, although it does have a scratch)
My question is (I haven't seen this covered elsewhere, sorry if I didn't search hard enough):
Do you recommend OEM or aftermarket parts? If aftermarket, any particular brand?
Anything else you suggest I should check/replace?
Crankshaft bearings? Any gears in the gearbox? (I heard of the problem with 3rd and 5th...)
I hope you don't mind jumping in here, but I think we can both benefit from it
