Can you use an OEM wrist pin bearing with a Wiseco piston kit? Are the specs the same? I got an OEM, because there was no Wiseco bearing available from the same place that I got all the other items. Did not want to make a 1 part order from another vendor. Now bad thoughts creep into my head. The top end is assembled (engine currently on the bench).
I have a 2003 RM250 and use WIESCO top end kits. I have always used OEM wrist pin bearings because it's the only thing that doesn't come in the kit. No fit or finish issues. My last top end went a year and still had 210 lbs of compression. I just changed it for G.P.
What part of Maryland are you in? I'm in southern MD.
Do the majority of my riding at Paragon in Hazleton, PA. - About 1.5 hours away or Blue Diamond Park about an hour away. Looks like your club has worked out some places to ride.
