Well, one thing, it's not the carbs but I don't know what it is. When I first start up after its sitting for a while, it's real hard to get it moving. After bein warmed up for a couple minutes I pull in the clutch and put it into a gear, let the clutch out and it barely wants to move, I can rev it up as much as I want and it'll barely move. After about 15-20 minutes of riding it seems like it works a lot better. With the carbs, I think it's just the pilot, I need to raise it. I am running 340 mains and the plugs are a nice light brown color like they should be, but it likes to bog down sometimes and not run right after sitting for a while.
