    Yes, the insulators all look pretty dark. Clean your air filter, make sure it isn't over-oiled. Check the voltage at the coils (O/W wire) vs. battery voltage. Determine how many turns the idle screws go in to lightly seated and compare to the recommended initial settings in this thread for your model:

    Carb OEM specs as per factory manuals - The GSResources Forums

    Place your GS carburetor, fuel or exhaust questions in this forum.


    The initial settings are usually a little rich. If it's still rich after all that you'll need to check float heights and confirm the jet sizes.

      Okay how are you riding your bike? You lugging it around town which would darken up the plugs or highway speeds? If it is highway speeds they are just a tad rich though not seriously. Other then that they don't look that bad at all. Your riding style will have an effect on the plugs don't forget.

        I've only put about 50 miles on the bike myself since I got it, and mostly those have been city riding and yes I've been lugging it a bit. I'm getting better about that, but I don't like to scream her down the street in my neighborhood.

        At this point I can't be sure how much hwy riding I will do. I'd guess for the next month or two that I'd be mostly riding around in town.

        I also talked to the PO and he said changed the plugs last year when he rebuilt the carbs. I can't say how he rode the bike.

        Would I be better of buying new plugs at this point or are these good enough for now? I'm guessing I wouldnt see a ton of difference.

          Take it out and run it up to redline a few times, afterwards a few less RPM's will seem normal. Blow out that carbon!

            So kinda like my car I need to take her out and run her hard and hot for a bit to clean out the gunk? (That sentence sounds really wrong. LOL)
