60Greyhound Posted April 2, 2020 Share Posted April 2, 2020 Hi all ... is it possible to do a hydraulic clutch conversion on a '89 GSXR 750 motor? Quote Link to comment
Jaydee Posted April 2, 2020 Share Posted April 2, 2020 Yes, just swap the chain cover for a slingshot 11 hydraulic case. You may have to play around with the push rod length to suit the slave cylinder. Quote Link to comment
60Greyhound Posted April 2, 2020 Author Share Posted April 2, 2020 (edited) cool, anyone on here have the parts I need available, or advise me on location? only offerings on eblag seem to be America/Canada. Scratch that... I've found a lever and complete sproket cover on FB market place... I'm guessing i'll need a 6mm stainless rod... any other parts? sorry for all the questions, just trying to get as many bits ordered up and prepped as I can!

wraith Posted April 2, 2020 Share Posted April 2, 2020 You will need, 1. Clutch master cylinder. 2. Clutch slave cylinder. 3. Sprocket cover. 4. Hydraulic line of the wright length. 5. 6mm bar to do push rod with Quote Link to comment
Sandman Posted April 3, 2020 Share Posted April 3, 2020 The clutch operation is not on the same side on the GSXR 750 88/89 as for the 1100 engine, and there is no pushrod on the short stroke engine. 1 Quote Link to comment
Captain Chaos Posted April 3, 2020 Share Posted April 3, 2020 What he says ^^^ Slingshots have the clutch operation on the clutch cover, not the sprocket cover. It is possible but some work involved (don't know exactly what). 1 Quote Link to comment
clivegto Posted April 3, 2020 Share Posted April 3, 2020 Can be done but you have to bore the clutch shaft out to accept the clutch push rod. Quote Link to comment
dupersunc Posted April 3, 2020 Share Posted April 3, 2020 Yep. You also need the thust bearing set-up from an 1100 clutch, the push rod that goes inside the shaft, the 6mm pushrod that goes through the seal, the seal with a hole in, and as Clive says you need to drill a hole through the gear shaft, which you aren't going to do with it still fitted to the engine.

Do you have to split the cases on these to remove the shaft? If so that's game over for now then... shame all other bits are interchangeable, Quote Link to comment
clivegto Posted April 3, 2020 Share Posted April 3, 2020 Yes you have to remove the shaft. You can split the bottom end with out removing the head & barrels though. Quote Link to comment
60Greyhound Posted April 3, 2020 Author Share Posted April 3, 2020 I might shelve this project for a while now then!... I've got all the other bits ready now too... Anyone used one of the conversion type pull cylinders that act on the original arm? Quote Link to comment
Captain Chaos Posted April 3, 2020 Share Posted April 3, 2020 why do you want hydraulic clutch? Quote Link to comment
60Greyhound Posted April 3, 2020 Author Share Posted April 3, 2020 Purely aesthetic. I don't like the cable wrapping around the block and up to the headstock. I go to a lot of effort to hide all the cables and wiring and the clutch cable spoils it sticking out the side like that. At least with hydraulics I can route it between the carb rubbers and under the tank. Also balances the clip-ons at the front so that looks better too. Quote Link to comment

Captain Chaos Posted April 3, 2020 Share Posted April 3, 2020 Easiest solution is to install an 1100 engine. 2 Quote Link to comment
60Greyhound Posted April 3, 2020 Author Share Posted April 3, 2020 (edited) @Captain Chaos... no fairings on this build Edited April 3, 2020 by 60Greyhound added content Quote Link to comment
60Greyhound Posted April 3, 2020 Author Share Posted April 3, 2020 @no class... yes, massively! byproduct of working on Motorsport for 20 years! But on the other side details like that make all the difference on a proper build Quote Link to comment
no class Posted April 3, 2020 Share Posted April 3, 2020 wish I knew about that kind of stuff.... one day I will get there..,, with alot of practice . 2 Quote Link to comment

Rode it 2 years like that without issue (and I'm 100kg without gear!)... I've had to change it now though as I've changed the swing-arm and put a normal monoshock/linkage set-up in. it has one from each side of the frame now, still meeting at the centre under the rear of the seat. I think it keeps the rear looking slimmer rather than having the bars up each side Quote Link to comment
