I have some questions for the plug chop on jetting. How do u do it first of
all.....I wanna know how so i can jet my bike pretty well. I have read
some other threads and they talk about running the motor at WOT for 20-
30 seconds in 4th gear on a slight incline, will this hurt my motor cuz i
don't think that i'm running lean. I have checked the plug since I put new jets in and put a FMF Pipe and Silencer on it. The plug was black and oily
with just a hint of tan on the electrode. I want it to be sort of black so i
know my motor is getting good lubrication at high RPM but not as black as i want it now.It runs good but it is a little
smokey until I get on the gas hard then it doesn't smoke at all or maybe
a little but i can smell the synthetic oil burning clean, but my brand new silencer already has the black spooge coming out the silencer hole, and I
don't wanna go through silencer packing every week! So basically i have
decided to jet it so it doesn't smoke barely and so it barely spooges. But
all i want to know is how to do the plug chop correctly. Thanx!

The soot on the plug is not unburned oil and has little to do with the ratio you are running. A plug chop (from what I read above you DO understand the correct way to perform it) will show if your mixture (air:fuel) is correct. If the plug is black your mixture (not your ratio) is too rich.
