    A Special Note about Email accounts!
    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    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.

So i was told by helpful memebers on this site that a 78 750 and a 79 850 can swap barrels and pistons, but does that mean you can use the 750 connecting rods and all the other internal stuff or do you need 850 stuff. and also would the 750 exhaust and carbs still work fine for the 850 barrels??
 
would i need to get a bigger set of carbs to handle the gas intake of the 850 performance, or would i just wanna go cv carbs instead of my mikuni??

Click to expand...
The CV carbs that would go with that (if they came of a GS) would still be Mikuni.

Just use the carbs from the 850 donor bike.

Carbs on early 750's and 850's are VM's - same size if I'm not mistaken. Not sure about jetting through.

On Basscliff's site he has both the 750 and 850 manuals, if you downloaded both manuals you could easily check to see how the jetting differs, if at all.
