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?

Never had that. Also never had to compare to anything like that, since I just installed the full hindle this winter.
You need a map. It will smooth it right out.
Check out this thread <a href="https://www.hayabusa.org/cgi-bin/busa/ikonboard.cgi?act=ST;f=10;t=23476;">PAIR Valve Mod<a>.
Actually, I got some Brock Blocks on da way. I had to pull all this crap off anyhow cause my HMF 4-1 is coming in Monday and I wanna get it on asap. I pulled the whole front end and speedo cause I got a 220 Gauge cluster off a 2000 modle on da way too. This is the most involved mo-cycle project i've ever taken on... for now. Had to finish the night/morning with a cold one.

I have the exact same issue. I added 5% more fuel at 0 and 10% throttle at 1000-3000 RPM. Did nothing at all. Running at 1250 idle. I've had the Dyno guys ride the bike and they say its normal..called support at powercommander.com, they say its normal too. Drove other busa's modded like mine, same sh-t. I'll live with it.
Oh yeah...did I meantion that when I installed the RS3's, I lost all my bottom end torque?

You mean a full system or just the cans? I was contemplating some yosh cans but I treasure my torque....its the main reason I got the Busa...if I gotta give any up for a pipe (or cans)...then that aint the set-up for me....I have the exact same issue.

Like Cheese said Tuning is everything, with the right set up and some who knows what they are doin it should be smooth. Also when I installed a TRE on my 2000 model it cleaned the jerking up alot.
That is for sure, tuning is it, did I mention money too! Dnyo and tunning to do it right your looking at 3 hours of dnyo time.
