I never looked into the crank bearings. If they infact ride on the case with no bearing I never would have bought my bike. That means once it wears out it can't be rebuilt. So my 54 Triumph will be going strong long after my 04 is shot and scrapped.

I learned all I need to know about life by killing smart people and eating their brains.
