Hello, I've been working on this bike a little while now, here and there when I have time. It hasn't been driven in over 16 years, and I'm now at the point of driving it around. Anyways, a little about what I've replace. The mufflers were shot, so I replaced them with a set of 16" slash cut mufflers from DimeCity, new points, new wires/boots/plugs, tore out the old air filter elements and replaced with the UNI Foam with a thin coating of oil, new coils....replaced with the generic coils from Z1enterprise, new gaskets and o rings for the carbs, set intake valves to .002 and exhaust to .003. So, I've set the timing, it's spot on...as the bike starts practically on the first crank. But my problem is it's running very rich at idle, I can screw the idle mixture screw all the way to snug, and it really doesn't sputter much. I can back it out a bit and it'll backfire a bit and you can smell it's running rich. I have also synced the carbs....best I could get was about 5in of vac on the right carb and about 6.5 in of vac on the left carb. That seems a bit low to me...any on know why that could be so low? While syncing the carbs, I noticed very small changes could effect the idle drastically, and it might rev to 4-5K. I'm almost the limit of how "loose" I can back the sync screw out.
I also get the bike to run decent for a little while. So, I took it out for a quick drive. It sputters when I give it hard throttle...would that be a float issue? If I roll into the throttle slowly it'll rev without sputtering. I do believe the float on the right carb is out of whack, because it was dripping a little fuel when I was hooking up the vac gauges. Also, while on the drive...the rpms wanted to stay at 3-4k when I got off the throttle when rolling up to a stop sign, or shifting gears.
I believe that's all I can think of for now. Sorry if it's difficult to read...just trying to get all the info out. Thanks for any help. I can also take a video of the bike running if that helps at all.
Forgot to mention, that after it was warmed up and I had it out for a cruise....there was some white(but smelled like gas)smoke coming out of the vent tube on the top of the rocker/valve cover.
My theory may be incorrect....just pulled the spark plugs...they're pretty white. The first two of the single plug are the right side, second pair are the left.
Right cylinder on right, and left....
This is the right cylinder.
Left cylinder.
