jetting?

[blastereatin250]

If I have my air box cover of and my snorkle removed and a k&n filter. Would it be worth it to rejet?

[jak1389]

YES! you would run too lean.

[blastereatin250]

ok, thanks. Any ideas of how much I should go up in jetting?

[jak1389]

move the main jet up a size or two

[blastereatin250]

ok

Aye, go up 2 sizes for starters. When riding if you ping or bog under load you need to go up some more. If it spits or sputters go down. Full Throtle.

50% and 25% throttle are different adjustments.

For clairty, Main Jet sizes are in 2.5 increments.
130 132 135 138 140 142 145 148 150

So for example 2 sizes would take a 140 to a 145.

my plug is the perfect color though. should I still rejet?

Did you put a new plug in then run it without the lid? If you just took the lid off, and ran it a little, or not at all, the plug will look perfect. Eventually, the plug would start to turn white. When I rejetted, my plug was a light brown. I went up to a 155. It took a week of riding until the plug became stable at a pancake color. i would go up 2 sizes, then put in a new plug.

[jak1389]
