Greene 1993 - download a picture guide from the 'net - in color - on how to diagnose spark plugs. That will be a good guide for what is happening. Here is one I found that is pretty good for diagnostics forcarb tuning....

Take the fully warmed up bike out on an open stretch of road (no traffic or other dangers). In as high a gear as possible (top gear is best), get to the engine speed and load you are starting to have trouble at, and accelerate with the steady throttle setting that causes the worst performance. After 4 or more seconds, quickly pull in the clutch and kill the engine at the same exact time. Coast to a stop with the clutch in (o.k. to use the brakes, just don't let the engine turn over), and immediately pull one (or more) of the plugs and compare them to the color chart. Determine what problem you are having by the condition of the spark plug(s) and compensate accordingly. Most likely your bike is experiencing a fuel (carburetor) issue.
The "classic" plug chop you might read about elsewhere is to go out on an open road, uphill, in fourth or higher gear at sixty or more mph and open the throttle fully for 5 to ten seconds before pulling in the clutch + shutting the engine off. This is quite dangerous on a high powered bike, as you could be exceeding 80 - 90 mph, and it only tells you about the air - fuel mixture at wide open throttle - in other words mostly the main jet size. Steve's (swest) recommended way is much better to diagnose the problem, and safer, too....

How about some basic bike info?
Compression test results?
Valves adjusted recently?
Ignition timing checked (and advancer inspected/cleaned/lubed)?
Coils good condition?
Stock jetting confirmed?
Airbox is stock.
Stock exhaust.
Do you have the manuals?
You can get several manuals from the links in my signature, and read the valve train warning before removing the valve cover.
