    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

Carb rebuild for GS850

My 1980 GS850G runs great but always smells like gas when running. I have noticed that I have fuel covering the top of the gearbox directly below the row of carbs. It appears to be dripping out of somewhere around the carbs when the engine is running. Not much, but just enough to smell and blow onto my pant leg when riding. Does anyone have any experience with this problem, and if so what do I do to fix it? I haven't planned on rebuilding the carbs since the bike runs so good but I will if that is what is needed.

Thanks!! Terry :)
 
Three things come to mind that could be causing the problem. First, you may have a leak in the fuel line going to the carbs. Second, one of the carb floats may have a leak causing it to fill with fuel. When this happens the float sinks in the bowl and allows gas to overflow the carb. Third, the float valve, also called float needle and seat, could be dirty or worn. It also allows gas to overflow the carb.

Check the underside of the tank also It could have a seam leaking You have to take it appart to determin where the fuel is comming from
 
My bad petcock did the same thing.

Take off the tank. If it leaks while it sits rebuild the petcock. Also change the oil! It may have gas in it.
