    I'd need an advice from the experts here. I adjusted the mixture screws and synced the carbs myself last fall. I haven't ridden the bike much since those adjustments, except for last week (600 km or so). Yesterday I took the bike for a short ride, mostly at slow speeds, engine rev'ed mostly below 4000 RPM, except for the very loast stretch where I opened up beyond 7000-7500. And then 2 kilometres at city speed.

    It wasn't a plug chop while riding, I removed my plugs this morning, here are the pics:

    Waiting for advices for finetuning. I haven't colortuned yet, I don't have the tool.

    I'm a bit concerned with the carbon deposit on the ring of plug #2

    Lower 48 in general. Otherwise Central Mitten.
    In my unqualified opinion.
    Those plug look great. Maybe just the slightest bit to the rich side.
    I wouldn't mess with it.

    Colors on the pictures are pretty much realistic, I didn't enhance the "latte" color on the porcelaine in any way. I'm amazed with how close to perfection they look without the colortune process.

    I wonder if I should clean the carbon deposit on plug #2 with carb cleaner and a toothbrush or just leave it alone?

    Looks great to me too. According to a tuning chart I have theyre a tiny tiny bit rich but that's where I'd want to be over lean. I'd leave it alone and enjoy the ride!
