cam mod re jet

[400-416EX]

Do you need to rejet when doing the cam mod on the yfz? I am running sparks pipe, no lid and pro design filter, I beleive 180 main, and clip in 3rd position

Yea, you almost always have the rejet after a cam change. Lets more or less air in and out.. so it affects your fuel air mix. Shouldn't be a big change.. probably just up or down a size or two depending on the difference.
