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.

Updating my Suzuki GS550ES to a 650CC

I believe I saw on this forum a few years back that you could swap heads cylinders pistons and rings etc from a GS650 16 valve over to my GS550ES or something like that. Anyone have some dope on this?? Trying to find pistons and rings for the ES is nearly impossible and if you do it is generally only 1 set of rings and I have not found any pistons. If anyone out there has a set of four standard 550ES rings I could use them. I am changing my base gasket, base 0 rings and head gasket. While I have it apart I thought I would re-ring it and see if I can get some compression back. I think the last time I checked the compression it was about 140 across.

Thanks much

If you have a 550ES, I am going to have to ask if you have an 8-valve or 16-valve engine. If you have an 8-valve, you can get the upper parts from a 650, but if you have a 16-valve 550, you are stuck, as there were no 16-valve 650s, nor will the 8-valve engine parts fit on your 16-valve engine.

Its not doable on your generation
be happy with the 64 BHP you have and quit looking for a measly gain of 9 hp
ok its a huge percentage increase but where does t live what rpm range?
 
Hey ciyper, I am not looking for horsepower, I was just hoping that if there was an upswap, parts might be easier to find. I am very happy with the power of my ES just hard as hell to find reciprocating parts for it. Magnafique
 
Thanks, yea I'm screwed, its a 16 valve. Thanks for sharing,
