Hey Guys!

I installed the 2" exhaust insert that is selling on Ebay. You basically remove the stock baffle and insert this piece...it's a flange with a 2" diameter pipe. Should be the same jetting requirements as someone with no baffle, so if you removed yours, what is your jetting?

I removed the cut-out on the stock air box lid so it's like the HRC.

I installed a 180 main and a 50 pilot. The needle is on the first position from the tip...raising the needle from stock.

I am not sure where to set the air screw. The quad runs good, but it is running rich. If I let it idle and then blip the throtle it will blow a little black smoke leading me to believe it's loading up. I think I have the air screw a little less than 1.5 turns out. Is that likely the cause?

How does the air screw work? Turn out to lean it or turn in to lean? I wasn't sure of this and i ran out of time to play with it.

Also, where do each of the jets come into play?
Pilot at 1/4 throttle...main at mid, etc?
Thanks!

If I have to screw my air screw all the way in, does that mean my pilot is too big?

I would put the 48 pilot back in and mabey even run a 185 main to start with. Mabey 2 to 2 1/2 turns out from closed on the air/fuel screw. Your setup is basically the hrc kit minus the cam so the jetting should be close, if not spot on.

SOunds like its about right already...rather run rich than lean. I was moving it out to about 2-1/4 and helps some...
