[03z400mike]

I live in utah at about 4500 and am going to travel to sea level to ride soon, can someone give me a general idea of how many jetting sizes i'm going to have to go up to aviod running lean?

What do you have done to the bike? are you running with or without a lid?

[03z400mike]

I am running pro flow with K&N filter wihtout the lid. It also has full titanium yoshi exhaust and head, 5mm yoshi stroke with 94.5 mm bore, 12.8:1 compression CP piston, 1mm oversized values, mild porting, racing cams, and a 39mm kiehn flatslide carb.

I'm at sea lvl I have a 42 pilot, clip on 3rd notch from top (tried the spacer washer that came with the kit but was too fat), and a 170 main. Main is a dyno jet. hope this gives you an idea. I have Stock motor, full exhaust, no lid k&n, no choke. Almost for got fuel screw 2 3/4 out

That's a lot more info than I expected WOW!! I never gave jetting specs for that type of setup before but I would start with a 170 main 42 pilot and the needle in the 2 or 3 slot from the top and 3 1/2 turns out on the fuel screw.
