    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.

Reboring from 750 to 850

Hi guys,
I am going to go through with a renovation of my 750 from 77 this winter.
In that connection I had planned to rebore the cylinders and put in new piston rings.

But now I am thinking about reboring it to a 850 and giving it oversized pistons. Has anybody tried that? Is it a bad idea? What would it mean for the the bikes performance?

Cheers...
 
Seems to me that somebody named Suzuki did exactly that....and then added a shaft drive to it and created a whole new line of motorcycles.

I think it may be best to wait for Nick to reply...I am sure he knows the exact specifics.
 
Wiseco makes an 844cc kit for your bike...that would be your best bet. Compression is at a managable 10.25:1 and would be a great boost for your bike. It is a 2mm overbore.

I'm thinking about doing exactly the same to my 1977 750. Are the stock liners ok to take the extra boring - from 65mm to 69mm?
