skylor Posted August 8, 2008 Report Share Posted August 8, 2008 Safest bore to go up to is .80 over but you don't want to bore unless you have to just hone and I think you can get about 3-4 good hones in before you have to bore. Alot of people think you get power from boring and thats not true Quote Link to comment Share on other sites More sharing options...
