Ken, You are too right about locktite. I was a roadracer, but most of the same problems apply. We also had the high-RPM vibration over long periods to worry about. I often threatened to buy stock in Loctite, and probably should have, but didn't, damm it. The thing to remember is to be sure the threads are CLEAN when using it.

Mark,
You probably want the purple loctite since a threadlocker is optional anyway - I think this is the #222 / small screw threadlocker; this breaks loose easily but does protect against vibration. I know that the blue is #242 (removable) and is what I usually use but it can require pretty high force to break loose. The red is #262 (permanent) and can be pretty tough to get loose and sometimes requires heat. They seem to make a product for everything - the RV guys have even found that the green (#290 I think) will stop a leaking gas tank rivet! I bet Bill Jepson has some real war stories about this stuff! The dirt bike racers keep the bikes together with this stuff since they don't usually use safety wire.

I assume you are talking about the front bearing retainer bolts. I don't use loctite on those but if you deem it necessary, be sure to use the lightest possible grade ie, lowest strength, type. I think loctite blue is the 'removable with hand tools' type.

Tracy,
I知 in the process of reassembling my RD2-C after doing the M/T bushing mod.
Is there a preferred thread locking product that I should use for the small socket-head bolts?
