    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.

Will GS1100g 2v TOP END WORK ON 78 GS1000e? ITS A POOR MANS BORE KIT LOL.

GS1100 BORE & STROKE= 72.0 x 66.0 mm
GS1000 BORE & STROKE= 70.0 x 64.8 mm

IM THINKIN THE HEAD MUST ALSO BE DIFFERENT BECAUSE OF THE BORE:eek:

I WAS THINKING OF BUYING AN ENGINE AND SWAP OUT THE TOP ENDS BUT IT LOOKS THAT THE CRANKS DIFFERENT.

Ssupertrap (something like that) built one in the projects/rebuild thread not too long ago. You should contact him. ;)
 
1100g

1100g

That EXACTLY what I want to do. Does anyone know how to get ahold of him :)
 
I'm planning to do the same as I managed to get a hold of a GS 1100 engine:)
The cylinder head is different due to the larger bore but the good news is that it has the D shaped exhaust outlet that's supposed to be much better?
What's not clear to me is whether the pistons are interchangeable ( beyond the diameter question) between the GS 1000 and the GS 1100?
The other question is about the possibility of using the GS 1100 crankshaft in the GS 1000 engine???
 
Pistons are interchangeable. Pin dia and deck height are the same. I was using 1100 pistons in our 1000 racebike till recently when we went Wiseco. Cranks are I believe doable but not a direct swap.
