im a little stumped on this one. 82 gl1100 45k miles . the bike sat in a shop for a year before the owner brought it over to me. they rebuilt the carbs and put new resistor end on the wires. Ends are honda and do have a resistor in them.the . problem is sooting up plugs and low vacuum. This is what i did. Went back thru the carbs and fixed a few items. Ive done about 8 sets with good outcomes but that doesnt mean anything right now.The floats seat and set to 15.5mm and it does not flood. It starts ez. and sounds good When I start it with fresh plugs with my morgan tune synch gauge hooked upit shows vacuum on all 4 fairly even . It idles OK . After it is warmed up to do the synch it is down on the morgantune where I cant read vacuum but still running. I can get a vacuum reading if i take it up to about 2500 rpm when warm.I checked the valves and adjusted a couple that were too tight. I pulled the belt covers and the marks line up. Ive done leak test on the manifolds and carb topsIf I pull the plug wires back just a tad when warm it speeds up. Im thinking coils or maybe a partially blocked muffler. or the jets have been opened. the plugs are sooty but not wetand it has fresh fuel and doesnt smoke from oil. After running for a while and goose it it will put out just a tad of black for a second. no air filter is on it.Any ideas ?. Thanks JB
