The bearing and wrist pin that went bad is the larger one ( odd ball size one ), I have never seen the larger pin and bearings in these engines before, but then again I dont have loads of experience tearing down a hundred of them either, it may be a very early version right after the brass bushings went away or something, not sure.
All I know is since I put the new piston, rings, pin & bearing in today that little rascal has really come alive, it lack a bit of low end torque from the throwd together exhaust I put on the bike I'm sure, but it will cruise easy at 32-34MPH now after just 12 miles on that new set of parts I put in.
It's pretty darn smoothe doing it too, and that makes it real nice.
I hope you just keep getting yours better and better......

cool & foggy at Morro Rock this morning... the usual summer WX lol
Thanks Greg !
I know I'm missing something...
7 mile speed run today. It just won't gather the R's...
Engine noise sounded like a periodic compression release engaged.
Maybe I'd better pop the head and inspect the gasket. Only reason I haven't is because I have none on hand and would need to make one from copper stock if it were bad... Just what I need, another project.
Ran through the radar sign at 24mph... best speed ever!
Gosh it was running horrible.
Interesting wrist pins/bearings, Map...
What's the group think is better, lighter for more R's and the nice looking roller cage, or the heavier pin with more rollers?
Which one went bad?
