1977 GS750 Suzuki

[Guest]

I have a 77 GS750. Rebuilt carbs. Vance and Hines exhaust. 105 mains 15 pilots.
Runs like a scared deer. But after only about a few miles the number 1 spark plug starts fouling. I am out of ideas as to what to do. Carbs are clean. Runs perfect when you clean the plug till it starts to foul out again. Any one have any ideas as to what I can do next. Thanks so much for the help.

Is it fouling with oil?

[2TechGuys]

No smoke. Never burns any oil. Plug is black. Sometimes is a little wet with gas. Installed 2 new plugs.

Did you ever get your "fouling" corrected?

Are you just curious chasing an old thread, or have a problem with your own gs750?
