Hey guys i have a 96 fourtrax that is snorkeled with an UNI air filter having some issues with stalling and backfire i just rebuilt the carb and got rid of the backfire and it will idle but when giving gas it stalls out. I have the stock jets on the bike, was wondering what everyone else is running for their bikes and what jets i should try using and what height is your needle set? Aswell where should i order the new jets from? (I live in Ontario, Canada)

I have a few 300s that are snorkeled and not re-jetted and they run great , what size pipe are you running , I find 1+1/2 inch pipe is what works on a 300 ------ are you sure the carb is clean , did you soak it in carb cleaner in a can where the entire carb was submerged and then blew out every port with compressed air ---- a crack or hole in the diaphragm will make it not accept fuel after 1/2 throttle

What size pipe are you using into the airbox? Do you have any sharp bends in the snorkel system? Is the carb a genuine Keihin or a China knock off?
