dang when i disabled my secondaries it really brought mine to life in the lower rpms. blips on the throttle at 3k rpms in first will easily lift the front wheel. running the ivans full muzzy, k&n filter, airbox mod map from riders forums maps.I installed the K&N on my 10Z and it went horribly lean. I have removed sec throt plates and are running juice box pro. The bike would not even idle it was sooo lean. Since then i have manually richend it to where it feels good. I am considering going back to the plates in and stock filter. It just doesnt have that crispness it used to when you really whack it down low in the Rs. I havent found any maps for my setup and i really dont want to beat the shiz out of it on the dyno for +2 ponies.
