At Sea level, I installed a full exhaust system on my bike recently, a FMF Powerbomb and a FMF Q2. As well as a Dynojet kit, when I was playing with the fuel mixture I leaned it out quite a bit, but I still had a really bad bog. I was told Accelerator pump timing needed to be adjusted, then I was also told to just leave the stock jetting and turn out the fuel screw and ill be fine. I've toyed with this carb quite a bit. Normally I can figure this kind of problem out pretty quick, but this carb has gotten the best of me. I have hot cams and uni air filter if that helps at all. The people at dynojet arent too helpful in my situation.
