Technical / Bottom End Rebuild: Necessary Parts

« on: May 12, 2012, 10:21:20 PM »

If the crank bearing are toasted then the crank might be toasted too. You can find good deals on Ebay for weisco bottom-end kits, I think I picked up one for my yz250 for $118

That was my original plan, but they don't seem to offer that kit for a 91. But if anyone knows if the 98-00 bottom-end kits are interchangeable i would definitely go that direction.

Technical / Bottom End Rebuild: Necessary Parts

« on: May 12, 2012, 04:24:05 PM »

Hello, I recently acquired a 1991 YZ 125  have decided to go ahead and rebuild the bottom end as I think the crank bearings are shot. What other parts are necessary on a bottom end rebuild?

So far I know these parts are necessary:

-Crank bearings and seals
-A full gasket set

I think oil seals may be as well, but i'm not sure if those are included in a full gasket set? Any help would be greatly appreciated
