    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.

The carbs are in my place right now.
I will try to work something out before the end of the week.
This is a nice set BTW.
Marc
 
I assured him the other day that Marc was a stand up guy. I forwarded him your PM Marc and also called and left a message. He said it was only 6 degrees the other day, but he will be really happy to have the boots and carbs that are right for his bike..cant believe the radiator hose and worm clamp arrangements!! And ALL the , what looked like Kawasaki or early Honda intake manifolds, were egg shaped and very out of round.
 
Just wanted to say I got the carbs from Chuck and they look great. Much easier for a novice like me to diagnose and fix problems with factory carbs. Transaction went smoothly.
 
Did you ever figure out if your bike had been bored out? Mine I believe has the Wiseco 844 kit, bores the stock 750 jugs to the maximum bore size/minimum wall thickness, same size as the stock GS850 jugs. If it is more than 844cc's, you'd have to either have the cylinders resleeved (boring the block to fit larger sleeves may give telltale signs of where the steel/cast iron sleeves are bored in and through the aluminum block, therefor the iron/steel is visible in the recesses between cooling fins in the thinner spots), or else the lower left front of the cylinder block would have 843cm3 cast into the flat pad on it, and the 850 cylinders would then be bored out further.
I will be boring mine out to 920cc's/72mm bore at some point next year, as I have some old stock MTC big bore pistons and a GS850 cylinder block. 1000 cc's would require GS1100 2-valve pistons (GS1100G? Did they make 2v 1100's? and are they the same piston height?), but the piston pins are 2mm larger diameter than the GS750/850 pins, and boring out the 750 rods to fit larger pins is uncharted territory. The 1000/1100 rods I'm not sure would work on the 750 crank.
