You did remove the clutch, correct?

about thirty minutes or until the case itself is 200 to 250 degrees.
As far as the fit of the Wiseco bearings, it's hard to tell without seeing what you have, but going back to the Honda
bearings is a good idea.

Good luck with it.

I'm not sure about their main bearing but you should measure the thickness compared to your oem ones.
The second mistake was using a different engine case. When I got the bike it came with a complete set of CR125 engine cases. The problem was I wasn't 100% sure which year they were from but the guy said they were for this bike. And I wanted to replace the old ones because the case saver mount had been broken off, and threads stripped in the right crankcase. Anyway, it turns out that the right crankcase from this set (of older cases I'm guessing) has a raised surface around the bearing on the input shaft of the transmission, whereas the 1998 case has a bit cut out around the bearing to allow the gear to rotate.
Anyway, It seems due to lack of experience I didn't notice this and didn't notice any stiffness like I did now and put the engine together. Oddly enough, I rode it like that and there was no oil leaks (and the wheel spun freely too). Thankfully there isn't any damage except for a notch ground in on the (now) old right crank case.
Now I know for next time! hopefully the left crank case fits together well now, although I will be very methodical and tedious with my inspection this time.
