Quick Fix

Took out the snorkel and plugged hole but now cutting out at the top of gears....? Running a 165main, k&n w/outwear, holes in the lid. Can I fix this with the airmixture screw or drop to a 160main? Before it did this with the snorkel on but with a 170main and then I dropped to a 165main to fix it. My air mixture is 3 1/4 turn right now.

What about adding some disks to your WB sounds like its rich I had the same problem so took my lid right off cut it and added a outerwares cover like in the Reviews section that works great I race XC no mud or water yet in the airbox I guess when I pulled the snorkle and was using just the holes I had it was not able to get as much air
after all that yea going down on main size would probably help :D

Forgot to add that 3 1/2 turns out seems like a lot should be 1 1/2 -2 1/2 you need a larger pilot jet 42 maybe 45 depends on temp

cool... thanks guys

just make sure ya leave the lid off if you block off the snorkel :)

didn't he say he was having touble on the top end. Changing the pilot jet wouldn't help him at all. The pilot jet only controls about the first 1/8th of your throttle.

Sounds to me that you have to drop the main jet one size,,,,or increase the air flow as stated above.

I agree...drop the main jet size.

How can you race XC with extended a arms and axle?
