Good shift drum needle bearing replacement?

[GeorgeOC]

Hello all, thanks for any help on this one! I have been looking up and down, even searching with the OEM part number, 93320-31501-00. Unfortunately these seem hard to source.

Might anyone have a good recommendation for a replacement needle bearing for the shift drum?

Hey, George. There's a few on eBay, search for "yamaha 93320-31501".

Member peanut has posted a lot about this needle bearing.
Some threads to review:

And, of course, it's available as part of MikesXS bearing kit:

Mystery solved. Chapparal Motorsports, in CA. had the OEM nos part. Not sure if their supply is infinite, but as of today they still had 2 in stock. Thanks!
