It was siezed when I bought it but I have since freed it up. I am in the process of rebuilding the motor but can't find anything on what the crankshaft diameter should be on the connecting rods and at the main bearings. Anyone know where I can get this info? I have tune up specs but not rebuild specs. Thanks! :confused: | | |
