What does everyone think about the air box mod or just taking the lid off and if I would need to rejet

 

probably need to rejet

just go full stage 1

 

oh yeah, going to need a new cam and change the sprocket ratios too.

which four wheeler are we talking about anyways?

 

cams are spendy, im rebuilding my engine this summer and im only putting in a higher comp piston, not going to ever do cams

 

09 kawasaki bayou 250, just looking for some ways to get a little more low end power for wheelies without spending $200

 

oh. you and your wheelies. strip all the weight off the front. put some more on the back. pray.

 

Ok thanks I can get it up in first but want to in second without going up a hill my friend makes fun of me because he can do them in 3rd on a 1994 timberwolf

 

you could try changing the gearing if you want and you will definitely be able to do 2nd gear wheeliie with different gear ratios for more low end power but of course you lose top speed but if you dont want to sacrifice that just do what sprinklz said just go full stage 1 get a performance exhaust, K&N filter, rejett, and instead of taking your airbox lid off i would suggest using uni air box vents Dirt Bike UNI Air Box Vents - 6 Pack | MotoSport comes with 6 and they are about 1 inch in diameter ive heard they help a lot with more air flow but dont let more dirt in.Its definitely safer than drilling holes in your airbox or just taking the lid off. Good luck

 

kind of hard to change the gear ratios, its shaft driven.

 

you add/remove a tooth on the drive sprocket

and/or add/remove a few teeth on the rear sprocket

thats how you alter your final drive ratio

more teeth on the front ups your top speed at loss of tourqe and visaversa

more teeth on the rear ups your tourqe at the loss of top speed and visaversa

larger tires does the same as more teeth on the front sprocket

and smaller tires does the same as more teeth on the rear sprocket
