I'm was thinking about ordering a jet kit for my 03 predator since I just purchased a Yoshi pipe. Who makes the best jet kit out there? I see FMF, K&N and Dyno Jet are some of the big name kits out there, which one works the best? The only mods I have are the full yoshi pipe, and Uni foam filter. Any help would be apprecieated...

 

I would not waste my money on them, I would go out and buy 3 or 4 jets and start with the biggest and and do a plug check. I have never bought a jet kit before.

 

Did you mess around with your pilot jetting or needle clip settings when you installed your full exhaust?

 

I did not mess with the pilot jet, I will before next winter. I droped the clip one, to raise the needle. I also turned the air screw all the way in and then turned it out 3 1/2 turns.
