I didn't have a problem with my install, although the lid on the box WAS slightly higher than with the stock filters. I just tightened everything down and have not had a problem.

I put my stock ones back in....when you screw the lid down, your putting to much pressure on the screws, the lid itself is actually bowed now cause of this(very slightly) but still bowed..You should not have that much pressure on those screws, its just plastic over time it will wear the pastic untill POP, there goes the threading..and opening will allow air in, dealer told me point blank, that could void the warranty as well if they saw a unsealed airbox(hypathetically) if it was a engine malfuntion issue...for the money, the filters should just fit rite.....

Your filters must have been WAY too big then. My airbox lid isn't bowed at all and they have been in for months. I only had to apply minimal pressure, the weight of the ratchet actually pushed down enough for the screws to start. You did the right thing by putting in your stock filters, if the K&N were that far off.

Should have bought the BMC filters. Direct replacement and perfect fit.

I was currious if anyone has any witnessed any before and after dyno runs with a k&n or simmilar? I have heard in some cases an aftermarket filter can actualy cost you hp due to turbulance in the airbox. Anyone else heard this?

Thats what the word on the street is. Lose HP with K&N, but will gain with BMC race filters. So bottom line upfront, stick with stock or go BMC race filters.

you could lose HP with an aftermarket filter however the biggest gains seen with a filter mod is when your actually at speeds of 120+mph where the filter can actually flow a good amount of air.. i dont trust anything the dyno tells me on a bike with an air scoop.

True. Bikes like the RC-51, 929 and 954 all lost HP with a K&N swap.
The BMC Race filters will get you 1.5-2hp on the dyno in a 1000RR and save you 1.00lbs of weight.
In Europe, the "DNA" filters seem to offer simular gains.
However, like Deezhul points out, dyno numbers aren't everything, real world performance is all that matters.
I'l gladly take a bike that dyno's @ 135hp if it could pass you all on the street :)

i live and die by that rule.. I dont care if your bike makes 180whp and mine makes 165whp.. as long as i am ahead when my 6th gear limiter hits im happy. I have no interest in dynoing my bike. there is a dyno down here that notoriusly puts down big numbers.. i could care less what that sheet says!!

Good point Deezul,
I guess Im just trying to make up some power I lost with all the extra weight I gained with the swingarm and Im told that apinning that big wheel i have is also slowing me down wich im sure it does. Obviously I can launch now...and full throttle in 1st with no wheelies unless i clutch it, but I wnat to make the power back to make up for the added weight and Im not a big nos fan. I would however, REALY love to do a supercharger...especialy since mines kinda more of a straight line bike these days. I know you say you dont believe in dyno #'s but have you or anyone had it done? any gains? Ive heard not much gain in peak #'s but it will flatten out the curve a little. I had it done on my F4I, but I know the guy who did it was wayyyyy behind on dyno sesions and I think he just gave me a 5 min tune especialy since I could not tell a bit of diffrence when it was done.

having my 05 cbr 1000rr on the dyno with k&n and stock I did lose 1-2 hp. Actually the stock filters breath better but don't last as long check them frequently you'll be amazed what gets into your box. I still use the k&n cuase i do track days as often as i can. and they do filter smaller air particals. I just pull them out and wash them, in they go next track day good to go. BMC's are nice but let alot of stuff through and what goes through the filter ends up inside the motor.. In the end personal prefrence....

Just thought that I would bring this thread back to the top of the list and see just how many people have had issues with the K&N filters. I was considering purchasing the K&N filters, but if they don't fit then the BMG filters are worth the extra money.
