I am having the hardest time adjusting my carbs.....It sounds great, til 20 miles liket it starts bucking, I check the plugs and they are a beautiful flat black....aaarrrggghhhh!I adjusted the front screw, 1 1/2 to start, then adjusted the idle accordingly/ sounds great.....Should I turn the fuel/air screw more out? Does that use more air less fuel? Then adjust the idle accordingly? Does anyone have a step by step for novices? Do I dare take it apart and clean it and use my keyster to rebuild minus the jets????????? Anyone wanna come over and help me? lol

Have you cleaned the carb yet?

Yeah, when I first got the bike.....I now know the proper measurements of things.....I will try again.

I ended up finding extra passages on my second carb cleaning more than once.
Make sure you force something...carb cleaner, compressed air, water or whatever into every orifice you can find and see where it comes out.
Make sure the slow jet and all its little holes are clean.

Is there a certain height that the main and slow jut are supposed to be at??????

Just snug them up and they should be right. There is no spec for height that I know of......except for the float.
When the float tab is just resting on the spring loaded tip of the fuel cutoff valve (spring not depressed), measure 26.5mm from the gasket surface of the carb body to the top of the float.
Actually, its the bottom of the float as installed on the bike.
