xXBlessedWithDeathXx Posted June 28, 2008 Report Share Posted June 28, 2008 hahaha. I wouldnt do that. who ever it came from probably just did that to sell it as a running bike. thats not something you want to do or run. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted June 29, 2008 Report Share Posted June 29, 2008 Yea I probably wouldnt want to do that ethire. The pistons will weigh different amounts and probably cause a vibration. I know people that race stock cars and they will run every other .030, 060. Or .030 on one side and .060 on the other. Blow a motor up and throw the parts in a bucket. Keep collecting parts until you have enough to build another motor. Good ol local dirt track at its best. For longevity purposes I would run the same bores. josh Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted June 29, 2008 Report Share Posted June 29, 2008 I'd hate to see what sorts of stresses a crank goes through with mismatched bores. Quote Link to comment Share on other sites More sharing options...
