So, hokay, I put a K&N filter on my bike and the PCIII with the map for a stock bike. Hell yeah, got more power for sure, but now I cant ride slow in 1st, 2nd or 3rd gear. The bike jerks uncotrollably until I either accelerate or shift to another gear. This usually happens below 4500 rpm. Is this just a fine tune problem that is corrected at the dyno? If so I'll not worry about it cause I got my HMF 4-1 coming in Monday and I'll be going to the dyno anyhow. Any one else ever experience this?
