1983 GS750ES

Wow. Looks just like my motor.

I'm at a loss.

Has anyone ever put a Hydraulic clutch on a GS?
 
That engine is out of a pop-up headlight Katana 750. It is essentially the same as the '83-'86 GS750 engine, with a hydraulic clutch. I think the cam timing may have been changed a bit as well for that model. Notice the gold-colored valve cover. That was on the Katana engines and is the dead giveaway.

I believe those bikes (pop-up kats) were made in '86, possibly '87 as well.
 
That engine must be a frankenstien, the 83 in canada has brushed aluminum covers on both sides of the engine and brushed aluminum valve covers. I see where the hydralic clutch piston is located on the pictures, and I am sure that is either a collection of parts from different engines put together or an engine out of a different year bike.
 
So we pretty certain on that being a Katana motor? Any way of telling for sure?

Thanks.
 
I think it will be the kat engine - it will bolt straight into the ES frame and has a few updates, one of which is a hydraulic clutch. You should be able to get hold of a manual off ebay etc pretty easy (its covered in the gs/gsx 750es manual) but just bleed it like you would with a brake system and that should sort it. If not, the plates and/ or springs might be gone, in which case a new kit should sort it. its not a tricky job but you might need an air gun to get the clutch basket nut off, couple of hours at a dealer but DON'T let them supply genuine suzi clutch plates cos they cost a fortune!!
good luck
