Jetting help

[Dang]

I have a stock carb, with a 67.75mm bore, and an fmf exhaust. I was wondering what jets I should use. Currently, I have stock jets and when I try to rev the bike it hits a sort of rev limiter and does not get into higher RPMs and it does not idle.

First off don’t run it until you rejet it, you’ll fry your shizz.

Go to the FMF website, they have jetting specifications, which are temperature and elevation dependent. Plus air filter and box.

Basically you need at least a 270 main.
List ALL your mods, air filter brand, snorkel or not, lid or not, and your elevation, and we’ll help you out
