That poor bike, but I imagine srads were cheap at the time.

Thanks, I'll try with fuel first.

The really shitty thing is that they only painted the left side of the engine.

I was poking around at my slingshot 7/11 this evening, it had been stolen before covid and recovered during covid and sat outside for way too long. I’d noticed some paint like drips on the left side of the engine and I finally tried seeing if they’d come off. Looks like they spray painted parts of the engine, exhaust, and oil lines, I guess they weren’t a fan of the factory grey. Any ideas on what might remove spray paint without stripping the original paint? Or should I just plan on stripping everything down to bare metal and giving the engine a refresh at the same time? I’ve got another 7/11 to finish first, so I’m not in any rush to get this one back on the road.

The list I posted is also for what's currently available still from Suzuki for sale. Suzuki being as cheap as they are, might have consolidated the cams down to just a few models to keep manufacturing as replacements. Only a guess.

They stuck the same intake cams in everything except the bandits.

M carbs should be 38s depending on where the bike was sold, and choke knob is on the side. Probably GSXF600.

Post a photo of it.

The one I have has an adapter for the fitting that spaces it down and on several models that creates interference issues betwixt tank and motor. I saw on here somewhere where the adapter was either milled down or a bung welded to the tank to accept it directly.
Yeah, it's a tight fit with the adapter plate in 7/11s, but I've ran them in slingshots. If you need more room, they sell a bung that can be welded directly into the tank. Planning on doing that with one of my tanks that is paper thin around the petcock area from rust.

Get a Pingle, lower profile than the stock petcocks.

This would explain why the 1000RR clutch MC I tried using years ago would never work. It looked good, but was useless.

I would turbo the bandit lump and keep the 1127 motor for the 750 .
Differences , bandit has a double roller out put bearing on the gearbox , weaker clutch , lower compression and the exhaust cam has shorter duration . As mentioned earlier the liners in the barrel are 1mm bigger in O/D . Stock bandit pistons are quite weak for turbo use so either gen 1 busa pistons or some aftermarket forged jobbies .
Thanks, I figured the 1127 would be more fun in the 750, but wasn’t sure if there was any real advantage to either engine getting boost. I’m sure I’ll be posting more questions when I start the actual build.

Can't imagine why a 1200 Blandit motor in a 750 chassis would be preferable over a GSXR 1100, especially if NA, so that's that question answered!
As regards which is better for added boost, they are pretty much the same engine internally and gearbox wise - the Blandit has the factory undercut 'M' gears which is good, hyvo cam chain equally good, maybe 'softer' cams (never sure if there is much difference) but the Blandito does have slightly thicker liners in the block so a bit stronger in that department. Assuming the GSXR isn't an 'M' or 'N' with shimmed valves, life should be good although shimmed heads work quite nicely in turbo engines and NA if you control the revs!
All in all - a non question LOL!
Thank you. 1200 will get the special treatment and the 1100 will start getting prepped to be stuck in the 750 this weekend.
-
And it immediately turned into talk about GSXF1100 engines and cams. Figured I’d ask in here instead.

I have an 1127 GSXR engine and an early 00s Blandit engine, one is going into an NA 750, the other will eventually get the boost treatment in an 1100 slingshot frame. Which of the two engines should I set aside for the boosted engine? Planning on doing pistons and possibly boring the cylinders with a goal of 250 at the rear with FI. Making the NA engine in the 7/11 fun isn't a problem, trying to figure out which of the two engines is the better candidate for boost is where I'm at now. Is there enough difference between the 1100 and 1200 heads to make a significant difference? Does one have a stronger transmission than the other? I've had a few 1100s, but this is my first 1200 and it's modern by oil cooled standards.
Also both engines are basically unknowns to me so I'll be tearing into them a little bit just to see what condition they're in. If I was to guess I'd say both have been sitting for maybe 5-15 years? I think I last fired up that 1100 engine in 2010.

Don't Hindle still make oil-cooled 750 exhausts? Alternatively, is there anywhere in US/Canada that will make you a bespoke system at a reasonable price?
Hindle sells exhausts for slabbies and 88-89 slingshots, but I've gone back and forth with them for 90-92 and until they can get a bike in to test fit the exhaust, they won't sell them. Really want to just tell them to make the down pipes 1/2" longer and keep everything else the same and we'll make them work. Yosh America wants $450US for a custom can, probably looking at over a grand for a full exhaust from anyone that knows what they're doing anymore. Pretty sure the UK has way more slingshot stuff floating around than we do. All of our bikes got totaled or are sitting in the garages of collectors now.

Just need to say, I had one that colour back in 1992, uk was water cooled not oil cooled like you lot over the pond.. It’s the best colour scheme for a slingshot ever
I know one or two members might not agree, but I’m right
It’s the only paint scheme I’ll keep stock.
-
Tried fitting my 1200 exhaust tonight. Does not like the fit on a 750. Definitely time for a bigger engine. Couldn’t even get the header on without removing the oil cooler from the mounts. Looked at my 7/11 that has an akro 1200 exhaust and it looks like with a straight oil cooler and spacers for the lower mounts, it’ll clear.

I was under the impression that the gsxf11 cams were the same as 1052 cams ?
So I was curious and checked the part numbers. The gsxf1100 intake cams were used in everything from the gsxf600s, to gsxr750s, to gsxr1100s. The exhaust cams were only used in the following bikes.

Sorry, the parts site is calling them Katanas, not me. I also don’t have a gsxf1100 engine and don’t see myself getting one any time soon.

Breaking down a couple of GSXRs and trying to decide what to do with the parts. One engine is going to go into a 750 because I want a second 7/11, and 750 exhausts are impossible to find anymore. I already have a naked 7/11, but I'm kinda enjoying riding bikes with full fairings again. The other engine is eventually going to get the boost treatment.
I've got an 1127 GSXR engine, a stock blandit 1200 engine, and a spare dot head that I wouldn't mind swapping onto either of them. Whichever one goes into the 750 frame will also be getting a set of RS38s and a full yosh system for a blandit. Kinda tempted to stick the 1100 in the 750 and save the blandit for the boost engine, but which one will be more work in the long run and which one will be cheaper for the biggest smiles when I do build a turbo bike?
I'll post up some photos when I go out to the garage later and might actually do a build thread for this one. This was the bike before I took it on about a 1500 mile road trip and a mate rear ended me and broke my exhaust.

Yeah, even on Eblag there isn't much anymore for these bikes here. Half the time the best option is just to find a cheap project bike and pick it of parts.

I have a 750M (long stroke) motor with bad head, a suspect B6 that was free, and a GSX750f motor that is likely rusty in the cases. Trying to make something out of nothing. Not many of these oil boilers turning up these days in the States.
Where are you at in the states? I'm constantly looking for parts on the west coast. Usually a couple of GSXR 750 engines on craigslist.

I'm not making it sound like anything, I'm just mentioning advantages of hydraulic clutch operation because some people feel no love for it.
Personally I also prefer a well maintained and adjusted cable over hydraulic.
I've had both on 1100s and was actually thinking about switching one of my bikes back to hydraulic, only because we can't lane split where I live now and the clutch gets a little tiresome in stop and go traffic. Otherwise I tend to prefer the feel and look of a cable clutch. I think it all really just boils down to personal preference.

8-12nm per the Suzuki service manual. No mention in the manual of them being wet or dry, but I would think a touch of oil would reduce the friction of them going in.
