K&N air filter/jetting:

[patrickj]

Hi guys, I have a 1999 Honda CBR 900RR Fireblade, I installed a K&N air filter, I already have a Yosh RS3 bolt on pipe, the bike runs a little flat, what do you guys suggest as far as jetting?

Probably no specific answer unless someone happens to have the same setup. Best thing would be buy a kit without about 5 or more size options in it... take it to a dyno and piss about until you get it right. But then again thats what I would do so its probably wrong.

i thought the 99 was injected

Well that would make it interesting [:p]

the 2000 model onwards is injected in the uk anyway and it is a shit setup it was eiher on or off which made it a bit dodgy round the bends
