    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...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

If I am getting fuel into the cylinders does that mean that the carbs are not blocked? Bike was running 3 months ago. Also can I change the carbs from my 85GS850 and fit them to my 78GS850 as they use a different design. Appreciate the help guys

What do you mean by "fuel into the cylinders" Do you mean leaking fuel into the cylinders or thru normal operation. If you mean by normal operation then they are more than likly not blocked or clogged. The carb change may be able to happen but you may have to change a couple of brackets around. I have a set of BS 32 SS Mikunis from a 84 GS 750 ES on my 81 GS 850 GL. They were the same carbs except for a couple of brackets. There could be several other reasons your bike is not starting but we would need some more information to figure out why its not starting.
 
the carbs are not directly interchangeable 78-79 use slide type and the intake mounting on the cyl heads are different. I would think they could be adapted. You would also need to modify the airbox connectors to fit best bet would be to keep the originals depending on your mechanical skills
 
Slides and VC carbs have different intakes.

Need more info. Even if fuel is getting through, it may not be through the right carb circuit or in the right amounts. Does this mean it is flooding (all plugs wet?) Indicates carb circuit, ignition problem, sticking float etc etc problems
