Hey Guys, just lunched my 74 MX250 (air filter was stuck up on the back where i couldn't see it and i did a race day battling with a face full of dirt) and when rebuilding it she has a 25mm crank pin and 311 rod. this is not what is in the manual or parts catalouge. i have a new rod and pin but dont have the bearing. are their any more common bearings for it? if not is the 93310-425N4 the correct bearing?
Are there any good aftermarket air filter options for these as my cage is knackered and never seals well?
Cheers
