Got1,
Man first of all your motor is the design I helped Jim set-up and is one fast sob. Number one thing is get some better pipes,and yes the v-force reeds will make alot of difference. I dont live that far from you and I run a 172 main jet and it is perfect. Have you done anything to your airbox, the motor has to flow. I have totally cut my airbox out, all I have is the front where the noss adapter holds the k&n. What does your plug look like? If your bike is running lean with that main jet you have in it you might have an airleak somewhere. Check your boost bottle if you have one I have had the rubber gromet blow out and cause my bike lean out. I threw that piece of shit in the trash. What kind of tires are you using, because if you still have stock tires they suck. You've got one bad-ass motor you just need to figure out what is not set right on it, trust me if you get it dialed in you will smoke all your buddies and there piped banshee's. Let me know if I can help. I know it is frustrating to get a bike dialed in , it has taken me awhile to get this set where it is today. Don't worry about your gearing right now you need to get your motor right before you get your gearing right, just put like a 16/40 on it and leave it until we get the motor right.
