Dear Gents, I have a K&N airfilter I want to fit, does anyone know what jets I have to replace? I am sure someone knows, thanks in advance, keep up the good work.

Re: K&N weber jets
Hi
What cans are you riding with?
I ride with open, golf ball roll thru types and K&N filter, and I can recommend the below. This is what I have fitted, and it is ok. I would like to fit a fuel regulator. This should also help. *=changed
Choke:36
Ventury: 350
*Main jet: 160 *
Air corrector jet: 170
*Ideling jet: 60 * (65 is to rich)
Air ideling jet: 130
Pump jet: 35
Starting jet: F7/110
Needle valve: 300
Kind regards Klaus

Re: K&N weber jets
If you fit it under the stock airbox lid you should not have to change anythiing. If you have modified your airbox lid maybe a step up on the idle jet

Re: K&N weber jets
If the backfiring is on the over-run at lower speeds,and you have no airbox,(just the oval type filter on top of the carby),it is probably one size too large on idles,but this opens a whole new can of worms as you may have to go up a couple of sizes in mains to compensate,or risk creating a lean hole further up the rev range.I know this information is contrary to the traditional,more air flow,must be lean,richen her up approach,but it is based on my experiences with the a similar setup contis/oval k&n/weber.Every time my p750 got backfiring on the overrun,I was rich on idles !
