Default Re: what did you do to your motorized bicycle today?

Dave, the Z-L rod is 110mm and is the type that doesnt use a caged needle bear on lower journal but rather just loose pin bearings, I had an engine with that set up fail on me one time because they didnt put enough roller pins in and one of them got in a bind and broke at high rpms, sent a piece up through the transfer and I bet you can guess what happened

as long as it has enough pins and the crank is true it should be a good running engine, that one experience kinda scared me of the Z-L rod engines but I know there are a lot of them out there running good for a long time.

I hope yours does great for you.
I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
