Ive deleted all the pollution gear, put a small filter on the crankcase breather & blocked off the carby vent tube, closed off the valve reed valves.
I bought a K&N so I'll live with it, I'm just a weekend warrior at this stage.
I read an interesting article re air / oil filteration & there is a a balance between air flow & filteration & the paper & fibreglass were the best balance, the drop in air flow was minute but the loss in filteration was considerable.
We race go karts & it's become mandatory to run a foam pod filter now, inside the airbox & we ring every drop of power out of the engines & there has been no drop in power since
This 94 zxr 750 has flat slide carbies, arent they standard ?
I'm after an inner Ram tube to the airbox if anyone has one ?
