Hey guys, so I’ve been looking like hell on here and I’ve found some helpful tips but still not quite as specific answer I need. I have a 2000 stock motor shee, still has the tors, and parking brake. Well I recently installed a set of t5’s and ripped the stock air box out and threw on the k&n clamp ons. I went to re-jet today and felt like I’ve tried it all and can’t solve the issue I’m facing. Currently running a vitos jet kit. New needles, 3rd position (tried 4 too) and a 290 main with 25 pilot. I tried a 330, 300 first. Anyway the issue is the bike idles strong and well, but when I give it throttle it hogs and dies. I appreciate any help.
