440 jetting help

[tvanthoff]

I was hoping I could get some help on jetting the 440 I am building. It has an exhaust, stage two cam, no lid with K&N filter, 11:1, no porting, & stock carb.

Can someone help me out with a starting point with a pilot, main, and clip position?



I have exhaustively searched all the 440 posts on jetting but I cant find anyone with a set up really close to this.

Thanks in advance for any help.

what kind of exahust are you running, that would help me give you a good starting point

42 pilot, clip one notch lower than stock and a 175-180 main should be a good starting point.

I saw that i have a 165 main on my 400ex. It has a k&N open air lid and a white bros exhaust.
