    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...

    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.

Cold #3...

So,

My #3 cylinder is cold at idle. I ride regularly on the freeway, and don't feel like it's missing, but it could be (this is my first suzi :-)). The other inline 4 I've had seemed just as smooth on the freeway.

But at idle, it seems to run fairly rough. Just after starting, I can just touch the exhaust pipe of cylinders 1, 2, and 4. But cylinder 3, I can wrap my hand around the exhaust pipe and hold it there for at least 2-3 mins.

I have tried swapping coil wires of cyls 2 & 3...same result.
I have tried swapping and regapping sparkplugs of cyls 2 & 3...same result.
When I pull the plug, it is almost black, slightly shiny, and seems to smell of fuel.
Any ideas (or should I just guess...the carb/s)?

I'm running a stock pipe, with most of the stock airbox, but an aftermarket filter with nothing around it in the battery compartment (I believe that part of the housing is gone??).
 
Clogged pilot jet or passage? Try some in fuel carb cleaner, any suggestions guys?
 
Because I'm suffering from this as well I've acquired a very small amount of knowledge from Chef and Keith and etc... back to the fundamental equation: Fuel + Compression + Spark = go. It seems your spark is ok since you swapped the coil wires, so I would also check compression to ensure its in spec. If it is, then focus in on carbs. As chef said, your pilot circuit could be clogged. You could also have a vacuum leak (check to make sure the boots are soft and supple and dont have any cracks and are connected correctly.) After running pull the carbs and check to see if there is fuel on the butterfly or on the inside of the boot. Also take a measurement of the float height and/or compare the amount of fuel in the float bowl to the amount in a functioning carb.

Thats all I remember for now :)
 
I've now got a second set of carbs on the way to me for a rebuild. When I pull of my current carbs, I'll let you know what I find.

#3 carb

I had the same problem but 2 and 3 carbs on my gs 750L I cleaned them with no new parts and it runs great
