Just finished installing my mtnk fix kit today and was telling a friend about the install. He asked if I changed the wrist pin bearings and I did not. I looked at my original wrist pins after speaking with him and saw there was some blueing. Are all you guys who did the fix kits change the wrist pin bearings as well??? really sucks if I have to tear down this motor after getting it all back together. There is only 1500 miles on this motor and was just doing the fix kit for prevenitive maintenece. Thanks for any advise.
