Left side bearing was good although the main seal was starting to go. The big end and small end conrod bearings were still good and side play acceptable. The right side bearing was shot for reasons unknown? I think it was just a bad bearing from the factory. I would expect 200 plus hours minimum on the crank unless you're riding style on a 500 is certifiable (maniac!).

When I pulled mine last month (crank seal). my bearings looked PERFECT. and they had TONS AND TONS of miles on them......

I was going to ask you about that.
I assume you replaced everything just to be safe? :-)

why would you put a bearing back in... that you massivly axial loaded from splitting cases (our main bearings ARE NOT designed to be axial loaded) reason Im such a stickler on the freeze heat method, vs the "pull em in" motion pro tool method..

Thanks!
I was wondering about that.
Now I don't have to ask :-D
