First off Boca is a bearing distributor not a bearing manufacturer. I stopped buying from Boca a long time ago after quality control issues cost me a couple motors and will never run them again. When I ran the VAC91s I too really liked them and yes they eat bearings. The go to bearing for me in them was the Swiss WIBs, lasted longer than anything else. Bearing fit and alignment is critical and I feel Jeff is correct about the VAC cases. And I'll agree with Mark in regard to synthetic oil, seemed best in those VAC motors at least for me. I used 18% Cool Power 2 cycle blue kart synthetic oil that Andy turned me on to years ago.
