Hey all, new here to the forums- found this researching my situation on Google, I think I've found my new internet home. I tried looking for some pics of the cases on the forums but no real luck finding the parts in question... I'm currently rebuilding my 01 yz250, the crank bearings (and I'm sure some other contributing factors) went out and destroyed everything from the crank up, including the jug. The top end is brand new and ready to rock but when installing my Wiseco bottom end, two parts fell out of the case when pressing in the new bearings- I can't seem to find them on any of the parts fiches in my manual(s) and I was hoping someone knew where I could find them a home! These both fit perfectly around the shaft with the o-ring that the front sprocket later mounts on, but this can't be their proper place as the case will not seat with that spacer on there. Any help is greatly appreciated! Thank you!
