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...

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.

Firstly here in NZ we call the 2 valve suzukis GS and the 4 valve suzukis GSX.
Wth that in mind has any body used GS1100 barrels and pistons with a GS1000 bottom end and head?
I have read that it is possible but has any body here DONE it?
What was involved?
Was it a straight swap? etc etc
My 1000 is an ET so it has the 34mm CV head, which I have read is the same as the GS1100.
A big bore kit is not an option as the NZ dollar is low against the US and the cost of freight is a killer.
Cheers
 
Two valve 1100 top ends fit, you only gain about fifty ccs since the 1100 had part of it's displacement increase in a longer stroke. So something around 1050ccs?
Can't remember how the compression ratio would be affected.
Gaining the use of CV carbs is worth the effort if that is what you want.

Thanks for the info
I have the CV carbs now, and can get an 1100 motor cheapish.
Things like the compression ratio and other bits and pieces are the info I am looking for. So I can decide if it is worth doing.
Cheers

I know mate and if I could find one down here it might be the go! but there arent that many around, lots of the GSX motors were used in speedway sidechairs and are now either knackered or to wild for the road
Cheers
 
as tkent said, the 1100 had a change in bore as well as stroke
dunno the numbers myself but a good mate "colin green" on this site has an 1100 and all the service manuals, shoot him a pm if you like, i'm sure he'd be happy to help

btw, if you end up going that route, i might be interested in some 1100 engine parts (that you may not need)
