Jetting Problems

[rustyboard2005]

I have an 06 Predator. The motor is all stock. I have a uni filter and the "Pure Polaris" pipe on it. I bought a dyno jet kit for it. Put the needle in it.. 2nd clip down. Did the air screw mixture. But it still does not run right. no low end power at all. I have a 165 main in it which is what's suggested by dyno jet. Im in Phoenix which is lower elevation. So I need some help on the main jet size I would imagin.

On my 05 TLD I have a HSP intake with KN filter and DMC exhaust. I run the stock needle 1 notch higher and have a 195 main jet. Runs perfect.

My buddy has the same quad with kn filter and pure polaris pipe. He runs needle the same and a 185 main jet and his bike runs perfect.

We are about 2,200 ft elevation.

If I were you I would go up 3-4 jet sizes.
