Meanbastard Jr Posted July 1, 2012 Report Share Posted July 1, 2012 I just finished a build on my sheet and fouled a plus but I had a really dirty air filter and I think that might have caused a huge air restriction whichcause the carbs to pull more fuel. Anyway I'm running 300 mains, 25 pilots 1.5 turns out clip on 3rd position on needle. It runs amazing but I think I need to run 280 mains 27.5 pilots. Any thoughts?

Finch Posted July 3, 2012 Report Share Posted July 3, 2012 jetting can be spot on and dirty filters or outer wears can make ya rich as hell clean the filters and see how it runs and id only jump down one size at a time IMO Quote Link to comment Share on other sites More sharing options...
