Is it normal to have an increase in engine noise after removing airbox and fitting K&Ns - the noise sounds like there is no oil in the motor which is obviously not the case (i have checked ). Engine revs perfectly from tickover to redline so i am presuming that everything is ok and that the noise is due to the fact that the k&ns dont suppress engine noise like the standard airbox does or am i missing something any further enlightenment is more than welcome

The standard airbox acts as an induction silencer as well as housing the air filter,so yes,you will get more noise. Youll get the individual sound of each carb sucking...it sounds mechanical,but it isnt. I assume youve had the carbs jetted & set up to suit. If the bike was running well before the airbox removal & youve carried out the necessary jetting/exhaust changes & had it set up properly...and theres plenty of oil in it...id say its fine. Youll get used to the noise eventually. Mines noisy enough with just a K&N & the snorkel removed. Pods are even noisier...

Pods, under part to full throttle are the "Sound of Music", or the "Sound of Performance"! Kinda intoxicating actually, that intake honk.

Aha, the legendary "pushme-pullyou". No, that honk reminds me of goose crap on the grass (well them calling overhead in the dark it the fall is meaningful as well as the first hopeful few who show up in the midst of a spring snowstorm to remind us that it will end). The "honk" I'm reminded of is that of a low restriction air cleaner on a big bore 396 Camaro when the 4 barrel Rochester QuadraJet carb opened up. As Crocadile Dundee might've said, "that's not a honk . . . . this is a HONK"!

If you've removed the complete air box and replaced with individual k&n's that noise is from your exhaust through the egr valve .get rid and put blanking plates on top of head

sorry the air valve that allows air into the exhaust port on over run or high vacuum to actuate valve at a preset limit. This is connected to 2 rubber pipes that connect to 2 plates on cylinder head that have a gasket underneath with reed valves its an emmision thing. What it does it burns off nitrates in the exhaust by introducing air through that valve ,raising the exhaust gas temperature ,thus alighting un burnt fuel in your exhaust system .That is why you get popping and or flames out of exhaust whether your thrashing or sudden closing of throttle img.photobucket.com/albums/v382/ZRXgremlin/Cache/2top/arse.gif[/IMG]
