    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.

Is it possible to put an oilcooled GSX600F engine in a GS550 1981 frame?
 
Of course it's "possible". Everything is possible. Expect to do a fair bit of fabrication work.
 
Yep, you can.
It is easier than putting the 1100 version which is taller. I got some pics of several. Email if you want a couple.
Tnx

Ive done it. You have to modify the gsx600f front rubber mounts a bit by shaving 5-6mm off them. They do mount to the 550 frame tabs after you do that. Then the bottom rear engine mount on the 600 lines up perfectly with the 550 frame, all you would need is a spacer to tighten things up. The top rear needs a new bracket, I made one with some 1/2 inch 6061 aluminum stock i had. The bottom side motor mounts have to be remade. The left side frame mount is welded on... couple ways to do that. (1) cut off and reweld (2) remake tab by copying shape and bolt hole, keep in mind to add some length to "new" tab to weld back to 550 frame with enough strength.

The right side bottom mount I used the same 1/2 inch 6061 stock and drilled the frame bolt mounts, then moved the engine bolt hole appropriately(sp?).

In doing it this way I was able to line up the sproket, swing arm pivot and rear axle dead on inline. And the sprocket is as close to the pivot as the 550 one was before. As well as being able to get the way the 600 engine sits in the 550 frame with enough room for the carbs, being able to service the valves. Not to mention getting the valve cover back on after mounting the dang thing.

You will also need to remove the oil pan and oil pickup from the enging just to get it in the frame. Trust me, I have the pinched fingers to prove it.

I also used the gsx600f swingarm and wheel for chainline reasons.... plus i wanted monoshock. Hope this helps. It can be done! Good luck sir. Ill post pictures when im close to my computer.
