2013 zx10 i have just replaced the original air filter for a k&n .
Can that cause any problems ?
Never been flashed and its de-cat'ed .
Has a gp growler exhaust .
After starting it it seemed to of got hot very quick .
I dont mean up to temp hot .
So we all ride liter bikes on here well most of us. I recently put on a power commander 5 and a k&n air filter i have noticed so much of a power gain that i am starting to think the bike realy does not need it. does anyone agree that the 1000 bikes already got with enough power for the average man
