I'm looking for the screw for the exhaust valve rod and also the screws from the exhaust valves themselves got stripped up pretty good. Can anybody help me find something like this? 1989 RM250 The guy I bought it off of said RM, but the cylinder head matches up to the RMX style in my service manual. Not sure if this would make a difference or not. I also need the bolts for the studs if anybody knows where to get info on those. Thanks a ton if anybody can help me. I had to send out my cylinder to get welded and replated. Ordered the new piston and trying to order these parts that got damaged. Thanks!
