Running Lean

"Now another tid bit that may help is when I intially start it up on full "choke" it dosent rev up real high, and drop as it warms and "choke" is removed. Also I have to constanly adjust the idle speed. When its cold it will be at 1K. After I ride it and warm it up real good it will move up to roughly 1500. So I turn it back down to a 1000 and will stay there till it cools off agian. "

Mine does the SAME thing. I have my throttle valves adjusted at 0.7mm and when its warmed up and starts to idle around 1500rpm, even with the idle screw all the way out I cannot get it back to 1000rpm. If you figure this problem out please let me know.

Is your bike stock? Id like to see what we have in common in both our bikes.

my bike is bone stock but might have an aftermarket airfilter in the stockairbox because it is not a paper filter, looks to be a K&N possibly. stock exhaust, stock VM26SS carbs, and rebuilt the carb with a carb kit using the stock size jets.

The Middle two plugs (3 and 4) are just right. The outside two are WHITE (1 and 4). Could the fuel flow be to little filling the 3 and 4 and starving the 1 and 4?

I need to figure this out. I hate riding it knowing this is goin on...
