I am planning on putting in a new piston on a fresh bore and I was wondering if you need to buy a new wrist pin bearing or will the original one work? thanks

You should use a new one. Been a few years since I got one, but I believe the bearing is included with Wiseco pistons. Double check on their site.

Better safe than sorry. I always replace wearable items on a tear-down. :cool:

You should really change out the **** and prone to break factory washers and put in some billet ones in. Some billet washers and a 99 RM 250 bearing will save you down the road from losing a couple bores...
