Re: [Nighthawk Lovers] 1985 cb650sc runs poorly at high rpm

Ok, heres what I have on my 700S. There are two hoses going into the cannister. One from the valve cover and the other from the top of the crankcase. A third hose goes from the cannister to the airbox. Pretty simple. By the way have you checked the air filter? If it is real dirty or oiled up it

Kiwi does that change anything you stated before about the hoses being run to and from the charcoal canister from everything I can tell it seems to be a California model but I can't see any designation of that nor can I find the Pcv valve I have the Haynes manual and it says the two hoses

The color of the plugs will tell you alot. 16k miles is not much. If you can give the bike a compression test that would be good. The loop, for sake of a better word is just a metal ring through which the hose from the air box and the clear battery breather tube are channeled to the bottom outside

Re: [Nighthawk Lovers] 1985 cb650sc runs poorly at high rpm

I had a vaguely similar problem and it turned out to be some vent openings in the top of the carb bowls. If you take apart to clean, check those, to. Plugs sound quite possible and cheap and easy. -- You received this message because you are subscribed to the Google Groups "Nighthawk

Re: [Nighthawk Lovers] 1985 cb650sc runs poorly at high rpm

The bike has 16k miles on it. I had the carbs complete apart and cleaned them up so I'm thinking it might be like you said the fuel levels are off because of how much jb weld I had to put in there to stop the leak. I will start by taking the hoses off and cleaning them etc. What do you mean

Re: [Nighthawk Lovers] 1985 cb650sc runs poorly at high rpm

Easier to work with you but you're too far away. So a few questions. How many miles on the bike? Are the spark plugs sooted up, black, grey, white or what? Check them The carbs need taken apart and cleaned at least. As with the hoses. One from the cannister goes to the valve cover. The two
