thrust bearing

I heard that it is a good idea to put a oil nozzle on the thrust and rod bearing to feed oil on a yz426f. i heard there is a kit? anyone know anything about this?

Never heard of it. Feed oil to what?

to the thrust and rod bearing. im not sure what they meant but i have 426 apart so i was wondering if anyone else heard about it before i put my motor back together

I know of no thrust bearing in the YZF engine other than the clutch release bearing. To the best of my knowledge, the 426 as is does not have a particular problem with oiling anything. There's a suspected issue with some of the earlier 450 quad wrist pins, but that's it.

thanks i guess ill put the motor back together.
