300ex jetting

['03'300ex'er]

I rejetted today, i havent got a chance to check the plug yet.
anyway how many turns out on the fuel/air screw is everyone running? i have a 130 main and 40 pilot no air box lid around 1500 ft. HMF pipe. does this setup even sound close?

It sounds pretty close. I think I'm running a 135 main but I have a Sparks full system. You might be able to go to 132. Not sure on the air/fuel screw. Just adjust it with the engine warm until you reach the highest idle and you should be fine.

With my setup I run a 40 pilot, 132 main. It jetted right on for sea level with 40-60 degree temperatures. Since all you have is a pipe and filter I would guess 128-130 main probably since you are at 1500 ft.

did a plug check today, the plug looks perfect. THANKS to all the forums on here!! i didn't move the needle yet, it dont seem too pull real hard up on top. starts great with no choke thats the sweet part of it all.
