I won't say which company did this to me, but I had ordered a pro-flow K&N and gytr jet kit, and they sent me a dynojet kit. So I decided to at least try the dynojet kit. I put in the pro-flow, removed air box lid, and pulled out pea shooter, these are the only mods I have done. I jetted to dynojet's specs for stage 2 which meet the exact mods I had done. But the problem is the setup sucks!! I end up with a huge lean spot on the bottom. I have richened the mixture screw, that doesn't do it. So I lowered teh clip on the needle and that got rid of the lean spot on bottom, but made it way to fat on top revs. And no matter what, I always get a huge backfire and flame from the pipe on decelerration...and that I haven't been able to fix. Should I ditch the jet kit and go to keihen jets again? What settings is everyone running below 3000ft.??
