Im trying to change my air filter Im just wondering if you have to lift the gas take. any help would be greatly appreciated!!! 05 636

 

Yes you do...did that myself a few months ago...if I remember correctly there is one bolt on top and 2 on the side...I had my seat off already and I loosened the pivot bolt as well...wasn't tto much work...

 

ya you will have to lift the tank.....if you need help just let us know or drop me a pm.....we will be glad to help ya out

 

I've heard K&N filters are the thing to put on....but I've also heard that without a power commander, your bike'll run a little lean. Is that a problem? Does is cost power? Recommendations?

 

This will start a debate but the facts are the K&N dose delivers more air than the stock filter. The BMC delivers a little more air than the K&N but not enough to make a difference for us normal riders. If you’re racing it would be enough to go with. They are both produced by the same company too.

Yes you will run leaner and may need the PC. The PC is great for FI bikes and is worth the investment.

 

What about if you have a BMC race filter? That plus a slip-on? What is really the downside of running lean, what kinda power loss? Dont mean to hijack brah.

 

Lean condition will burn up your pistons. Bad to be lean!

You should not lose any power by adding a aftermarket air filter unless it drastically messes up the AF, real lean or real rich.

 

Is your bike stock/ stock pipe? If so, it should be OK but if you have a Slip-on you may run lean especially if it's a full system.

 

Somehow, this thread is going on in 2 places....
I ordered the K&N yesterday, should be here tomorrow - tune-up with air filter and steering damper go on Friday. What I've read was that K&N doesn't require remapping with a PC (but that didn't take into consideration aftermarket pipes - 2 bros here). The BMC (made by K&N also) has even greater airflow, but states that it needs remapping for the air/fuel mixture.

Sunnuvabich, looks like I'll end up with a PC before too long......

 

I feel your pain gsims, having a bike is a damn money pit!! DO i want to fork out $300 for a PC no way, Id rather buy a XBOX3.
I have a BMC and I dont know the difference but I havent had the bike b4 the BMC was put on. Im going to put my yoshi on this weekend and see what kind of difference I noticed.

When I had my mustang I put off road h-pipe on it and it was definitly running lean, check engine light came on all the time. I put these sleeves i had to buy on the o2 sensors to trick it. I guess the remapping is like this and its prolly gonna have to be done. Dont want to ruin our engines!
