I know that stock jet size for a warrior is 145 but after adding a pro-circuit t-4 and UNI or K&N filter how many jet sizes do you think i should go up? I was thinking like a 150 152. Also what brand of jets do you recomend?

thanks

Try dynojet 150 or 155 if you are on a budget look at wppracing.com my cousin got his jet kit there and I can't tell any difference and I think his costed like 20 bucks or something

 

I am running right know 150 Dyno Jet kit on mine you should try the 150 first if you see its not working for you then try higher also change the plug and look for a tan look if the plug looks tan its right on the spot and you should be good to go.

 

If you dont have the money for a jet kit go to your nearest yamaha dealer and tell them the jet size you need it should be around 2 to 3 bucks or so.

does that mean it only comes with three jets? do you know what sizes it comes with??
