I just had an Ivan's jet kit installed and dyno tuned. While I gained 3 hp and 2 ft.lbs, the driveability now sucks. There is a lean spike at 2500 rpm, then it runs rich between 3500-6500 rpm, then it's pretty good all the way up except for another lean spike around 9500 rpm. So basically the bike bogs and has a few flat spots down low, then pulls alright up top. My tuner said if he was to adjust for the lean spike and bog down low, then it would be rich and soggy up top. He said that is all he can do cause of the lack of jets that are included in the Ivan's kit. This sucks, because I thought the bike drove better with the stock jetting. What am I missing here?
