gday guys, I have a few problems at the moment on my 03 honda cbr 600rr. Firstly, i recently had a blown up engine and apperantly the top end have been damaged. I also, have pulled out the engine and taken out the crankshaft and it appears to have a broken bearing. I went to a crankshaft specialist and said that he would be able to fix it by regrinding parts of the crankshaft, and all i had to do was the find a 30000-40000 1 mm over bearing. I have tried a few places like honda dealers and bearing shops, and they dont appear to have them. I live in sydney, and i need help on finding a 1mm over bearing. In addition, what else should i do with the engine rebuild??
