ok so when first started idles fine and everything rev it up comes right back down to idle.just seems like after you start riding come to a stop idles little bit higher not insanely high.plug is brownish black but more brown so i no im not lean.sprayed carb cleaner everywhere i could have a leak.no signs of one.have my filter right on the carb could this be causing it to act somewhat like an airleak making it rev little higher?
 
check your a/f screw try screwing it out some to give it more fuel and see what happens. all mine idle a lil high when you come to a stop but if you feather the clutch a tad it idles normal again
 
turn it in/out till you find the highest idle, if the highest idle is between 1.5-2.5 then the pilot is the right size, if its more out then its to big. so it shouldnt be out more than 2.5
 
well 1.5 turns out is highest idle point.seems fine i mean when somewhat warm but not ridden yet rev it up comes back down to a lower idle but not dying.after i ride it for a minute stop rev it up it comes down to idle quick but idles a little higher.think i just need to mess with idle screw.thanks for the help
 
turned it about 1/4 past 1.5 turns idle comes down like normal.yesterday it was 70 today its like 50 something.so im thinkin on warmer days i need to go to a 270 main to even it out.man this jetting sh*ts fun.
