I am located in North Carolina, my quad is running a 2oo main jet and a 42 pilot. Everybody on every other website is stating smaller #s. I have a fmf full system, k&n filter and my airbox cover is removed.

if everything else is stock then that seems way too fat. do a plug run and you'll see you will have to jet down.

this is leaving me with a tan colored plug anything else is white, and running to lean. If I ran a 160 like others say I would melt something

holy ballz 200 is huge! But ever motor is different. Give some more info like temp, elevation, and other mods? Also it doesn't make sense to be running a 200 main and a 42 pilot, those numbers are so far apart!

i would only run a 160 or so in my built motor. i would say that is a good starting point. i wouldn't go larger i don' think. you will loose too much upper gear power.
