What type of muffler, jets, and the hole dia in the air box?

 

Airbox-EHS Racing lid with Outerwears cover and a ProDesign (ProFlow) foam filter (I recommend staying away from K&N!).

Exhaust-FMF PowerBomb header and Q4 muffler.

Jetting-Dynojet kit. There isn't any pat answer to this. You can't just have somebody recommend jets over the internet or even depend on the recommendations that come with the kit or the muffler. This needs to be done emperically by someone with experience! If you are new to this and want to learn, read everything you can and have lots of patience!

 

x2 on the stay away from K&N, especially if you ride in dusty conditons

 

white bros pipe, k&n filter, and 170 main jet.

if u ride in dusty conditions, everyone says stay away from k&n. not true!!!!!!!! thats what they make pantie hose for! cover up everytime you ride and you will have a clean and clear filter with no problems. i ride with NO AIR BOX. through creeks, dust, grass, and anything you can think of. with a major rebuild, 115 octane gas and no air box, which has been like this for a couple years, i have never had a problem!
