When I go to put my homemade sync tool on, #1 is drawing way to much vacuum. I BELIEVE this tells me vacuum leak, correct? I've been pulling my hair out. I checked the choke plunger, new carb holders, float levels checked, checked all rubber orings in carbs twice. Still, too much vacuum @#1. Also plugs are black as can be @ cylinders 1-2-&3. #4 is a good brown color. How can #1 plug be black, but have a vacuum leak?(so I think). Any help here would be great. Needle & seat?
Bike has dyna s with dyna green coils. Timing is dead nuts. Have yet to do the coil mod, but wouldn't 4 be black too if ignition was the problem here? I was getting an off idle stumble bad at 1/8 throttle. Also getting black smoke @ idle telling me too rich.

I have done a little bit of vacuum measurement at work and everything seems to be measured in inches of water or inches of mercury... I've never heard of "inches of trans fluid" :dry: :S
Don't be ridiculous! It's only a flesh wound!
