That is very tidy, great work sir!

Beat me to it!

Check the piston diameter, that kit's for a single disc so it's likely to be smaller than for an 1100.

Probably, my Harris was originally on a GS1000, now it's on a GSX1100ET and the rear mount fits the GS750 frame they are/were both in. I would think the only issue might be the rar mount on your 1150.

Very neat, are you using the OE master cylinder & does it work ok? I fitted a 16mm clutch cylinder on the left handlebar to operate the back brake & it's probably better than the front!

It's the centre/centre distance of the mounting bolts & having measured the installed height of the std tap and from Clive's pic it seems a Pingel is the solution to my problem.

Many thanks Clive, V helpful.

Couldn't find the specs on there, can you measure the height of yours for me?

I have a fluted GS1000 fuel tank on my 7/11 & RS34 flatslides, unfortunately the 44mm fuel tap just rests on the top of carb No.1 and hits the carb top when going over bumps/rough ground etc so I have been looking for a lower profile fuel tap, the later taps without a lever are shallower but 50mm bolt spacing. Does anyone have a 44mm Pingel fuel tap & could measure the installed depth for me or does anyone know of a shallow 44mm tap without a lever? Thanks all.

Have you checked the new needle valves are the same as the OE ones?

I also used a ZX7R clutch cylinder on an 1100K with standard slave & had no issues.

For reference this company knew immediately that I had calipers from a 1980 GS1000ET just by telling them the piston dimensions https://powerhouse.uk/

Does anyone know what models use what size front caliper pistons? Mine are 38 X 36 but all the replacements I can find seem to be 38 X 22 which makes me think Suzuki used calipers that look the same externally but have different internals. I thought my calipers were 1100 Katana but it was many years ago that I bought them so I may be wrong. Thanks, Mike.

Quick update, I had forgotten how good a Harris race baffle sounds on big old 4s and also how awful the lights are! I remember Joe Lucas used to be called the Prince of Darkness but the 750ES headlight isn't much better. LED headlight bulbs seem to get mixed reviews so not sure if that's the answer either.

Yes that's the problem, I want to keep the shape of the ES headlight glass as it's in an ES fairing. I was wondering if anyone has fitted LED internals.

Has anyone put an led headlight in a GSX750ES? I know there's a thread on fitting one to an ET but would like to keep the ES headlight shape if possible. Thanks.

So I insured it yesterday and later this afternoon am off to bolt the last few bits on then off for it's first ride since 1999 and my first time on a bike in about 15 years! Slowly seems to be the best policy

Your broken clutch won't help but if it's still sticky when rebuilt, start with chain adjustment i.e. the easy/cheap bits & work up to gearbox bits.

Thanks to all, I like to keep any mods to the same era so the wheels, shit brakes, tiny forks etc are staying. The only late mod currently going on is a handlebar radial clutch cylinder to operate the rear brake.

I recently had inspiration to dig my old 7/11 out. I built this from parts 35 years ago but last used it in 1999. It was laid up properly, oiled bores, fresh oil, drained fuel tank & carbs, drowned in Scottoiler preservative spray twice a year etc. After fitting new plugs, battery, oil & filter, replacing some fuel lines that had perished, eventually remembering to connect the harness earth and giving the carbs a once over it started! A few other jobs have been done & I'm just waiting for some caliper seals then it should be good to go just in time for winter :-(
