Hi guys I have had my nsr in peices for about ten years, procrastinating and gathering parts, I finally came to put it back together and found this while cleaning up the crank cases. https://youtu.be/q6N2ZxcGGpw

I uploaded a vid showing the notches on the crank cases where the bearing locating pins sit. One is ok, still square one has a small amount of damage and the third one looks quite misshapen from the bearing moving and the opposing part on the top casing has a small amount of damage.

Please watch the video and any advice would be greatly appreciated. Thank you all in advance. Regards Dave Roberts
