jetting help

[tclines]

Just installed HMF sport series full system, K&N filter with Outerwears no airbox lid & a Sparks advanced timing key and I'm between 700 & 1000 ft (ASL) which jets should I use ?

what quad? I would guess by the timing key a 400ex? If so, try a 158 pilot and a 40 pilot. You may end up with a 155 or 162 main by the time you're done, but that will get you in the ballpark.

I installed a 160m and a 42p before posting this thread. The big problem is when I first hit the throttle it's real sludish after that it screames. So you think I should just go down to a 40p?
