thanks

i think 110 should do just fine, what's your compression?

Someone will probably correct me, but depending on your elevation, I think 280's might be a little lean...?

If you put your compression too high you will lose alot of overrev on your motor, you will gain alot of torque, i think you would want around 180 compression. Maybe a 19cc dome.

What kind of air filters are you running?

so 19cc domes.i have k&n filter with the lid off.thanks for the help

I see that you said your crank is stock, is it welded? it should be if not. 280 might be a little lean, i would def do a plug check. Might need a 290 or 300. If it runs good and plug looks good then your good

WE really need to know your elevation, it will affect both your jetting and what domes you should run. You can go on Google Earth, I think, and find your elevation.If you are at higher elevations, your jetting will be leaner and your domes should be smaller than if you are at lower elevation. High elevation has less oxygen in the air so you need less fuel also, and there is less atmosheric pressure at high elevations so the cylinders don't fill as well and therfore you need to squeeze it harder.
