'04 Yamaha Warrior 350 jetting

[RDub]

Hello

I am installing a ProDesign intake with K&N on stock air box with lid off. Stock pipe and carb. I believe I need to re-jet. The Warrior will be running on the beach and trails up to 3500 feet. What size main jet should I start with? IRC stock jet is a 145.

Thanks much

I would start off by putting in a Yamaha Warrior Stage 2 Jet kit and go from there. It'll give you the ability to adjust that thing out. Instructions attached. Here's a part of them..

"Remove stock main jet and replace with Dynojet main provided. If you are running the

stock exhaust use the DJ146 below 3000 feet, DJ142 from 3000 to 6000 feet and

DJ138 above 6000 feet. If you are running an aftermarket exhaust, use the DJ148

below 3000 feet, DJ144 from 3000 to 6000 feet and DJ140 above 6000 feet. Be sure

that the jet you are changing is the main jet. Discard the plastic cup that is on the stock

main jet."
