    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.

Does an 1150 block fit 1100 cases?

I think the cases are the same for the two with different size cylinders and a different head.
 
Thanks, from what I have read in the perf section the wrist pins are larger on the 1150 which creates the problem.
 
Its a straight swap.

Then you need the 1150 cylinder head, rocker box, and longer barrel stud's but I' m not sure which ones and how meny.

Suzuki mad

1983 GS(X)1100ESD

It's not a straight swap. The 1100 case needs to be bored to accept the slightly larger cylinder sleeves of the 1150 block. I've heard of some people clearancing the cases for the 1150 cylinders by using a round bastard file to slowing remove material until the cylinders fit into the case.

Suzuki had to put larger liners so they could have three overbore pistons kits available for the 1150.

Also the wrist pin issue is real, The11's use 18mm and the1150's use 20mm wrist pins. Need to change pistons or change cranks
