Pretty happy with ol yeller, but wondered if a K & N filter would give an increase in HP, however small. I assume it already has a ram air, so there is nothing out there to buy, to increase forced air (cold air intake) like with cars and trucks???

P.S. Already have TRS carbon exhaust and power chip.

 

ive heard that sometimes the stock filter works better. also you could always get a powercommander (im not sure what you are refering too when you say power chip) also what about velocity stacks . use the search option an dim sure you can find a lot of different ways to power up your bike. also you could just change the gears so it feels like it was more power

and on a side note . use www.photobucket.com to upload your picture for your signature

 

Got the e-mail a few days ago, THANKS. Will revisit, Wife Calls

 

I have a K&N and TRS slip-on on my F4i but didn't really notice that much of a change. I thought it got a little more reponsive but maybe that is my imagination. Only a dyno will tell me for sure. I'd be surprised if I have any added horsepower because of those two mods. I don't expect to really see any difference until I get a power commander as HAVOC stated.

 

my bike has a k&n , powercommander3 ,shorty slip on , and quick accell sprockets . big improvement ran 10.5 n qt mile powers up in first around 9500 rpm second the front end feels light around 11000 but not enough power for me. now fabing up turbo kit

 

That is fast for a 600. Nice run.
