Big Dan has good info.As a kid I had a lot of bottom end failures because of the type of oil I was using. To the point were my dad was buying boxes of bearings. He had it stuck in his mind that wolveshead premix was good for any 2T and he was right to some extent. Ended up running 12:1 in that little air cooled cr60 oil eater. Once I switched to zook in 84 along with water cooling and the dealer cut us a cash deal on Suzuki cci did I start using the motorcycle specific stuff @20:1. 1983 was the last time I had a bottom end seizure that I can actually remember.
