Ok i'll just got off the phone with the guy at boca bearings. I wanted to get some upgraded bearings for my engine. He told me there is no way that the bearing was 11.2x21.2x4,8mm. He is trying to sell me a 11x21x5mm bearing. Will this bearing fit in my crankcase. I have the .12 trp pro.
Best you remove the Bearing and measure it, I purchased a 11x21x5mm bearing and it didn't fit.
