which main jet for my mods?

[interceptorz28]

Hey all,

I have some stuff done and am gonna bump up my jetting. Bike was riding fine the way it was, but I had some jets lying around so I figured I should tweak it.

I have a 152, 158 and 160 main jets.

What should I go with first?
( I am at sea level btw)

It would help if you defined "some stuff". by looking at your sig. all you have done is a pipe.

[honda300EXtreme]

yea,, please define what you mean... if all you have done is a pipe
you will be between a 152-155,,, but let us know

[interceptorz28]

yup just that full pipe.

I would put the 152 in and see how it runs, and maybe remove the air box lid, depending on your riding conditions.
