ok the bike is running rough at cold start and idle
then blows black smoke when reved in N and sometimes pops fire.
but runs alot better when warm but still makes a surge at slow speeds and dies at idle after 45 seconds.

The bike had a float level problem that flooded the engine so i bent the float down to increase presure on the valve and fixed it .

i didnt let the bike warm up when i just pulled the plug, stock pilot jet
still.
im going for a ride now .
but it pulls great .

well i cant tell if the rev limiter hit or it broke up revving it in 2nd gear.
i ran it topped out on the rode ran clean ,and it hit 50 mph and i have 27"s on it , she still had one or two more in her but i backed off.

plug after all warmed up and a full throttle run .
plug # DPR7EA9
OUTSIDE TEMP 49 F
SEA LEVEL



does that look lean?

 

[vettepin]

no smoke or poping , but that plug is pure white and the point is gray ,i think it might be lean at idle and really lean at wot still. i do have a cam in it.
