350BANSHEE350 Posted February 27, 2008 Report Share Posted February 27, 2008 mod wise i would say somewhere around 330 for mains, give or take some, i am not to good with port work jetting and low elevation, and deffinatly 27.5 or 30 pilots, thats my close estimate Quote Link to comment Share on other sites More sharing options...

bunboy1 Posted February 28, 2008 Author Report Share Posted February 28, 2008 hi all, the pilot jetts are stock which are 25. the mains are 280 which came with the t6 kit. these jets worked great for the stock crank with pipe kit, but i am clueless which jets to use now with my new mods, please help, thanks.

Contact the builder who did your portwork, he should be able to get you close. Porting is kinda the wild card when it comes to jetting because no two builders port jobs are the same.
