Yeah, even the blue forks that I've seen on that site are pretty faded at this point and could definitely benefit from being redone. Also any forks I get I plan on having fully rebuilt.

I can’t remember anymore if there was any difference in the front ends that came with the blue forks. It wasn’t just an SP thing right? I’ve got a US N model with pretty tired forks and was thinking about seeing if I could find a decent set of the blue anodized ones mainly because I like how they look. Also there are a lot more W forks out there than oil cooled forks at this point.

Hindle sells a full system for the 750 J/K slingshots. Some 1100 and bandit12 systems will fit, but they do all tend to hang a bit low and can interfere with the oil cooler. I’m currently running a full Akra off a 1200 on my N, but I would prefer something that was a bit tighter to the oil pan.

Not gonna get that much more power out of it on a dyno with the air box and stock exhaust on it. It’s nice to see an all original survivor from time to time here in the states. Glad you got it sorted.

Which slingshot? 88-89, 90-91, 1100, 750? I might have some that I could trace/photograph.

I'm only familiar with the GSXR harnesses, but they all have a sub harness for the headlights. If the bandits are the same, it's pretty easy to sacrifice one to hookup any type of headlights you like. You can even get some pretty trick LED single bucket headlights now that will take a standard H4 plug.

You could always ditch the fairing and stock headlights and put on a nice big single bucket headlight.

I'm out in Portland, OR. That bike is really clean, definitely hold on to that full yosh system. Aftermarket exhausts are pretty much impossible to find for our gen of 750s at this point. I was running an 1100 exhaust on mine, gave up on trying to find a used exhaust anywhere. Here's mine. I rode it from LA to PDX last fall and haven't really touched it since. I need to go through the whole bike again now that it's finally starting to warm up out here. I sure do love GSXRs with colored wheels.

As others have said regarding the engine, all depends on how much you want to spend. Flat slide carbs don't lose much value if you buy them and decide to go sell them later when going with a turbo build. I've got a full Akra bandit 1200 exhaust on a slingshot 750. Gotta space the oil cooler out, but otherwise it fits fine. Most of the 1200 exhausts should work on a GSXR frame with a little bit of tweaking. Full exhaust and a jet kit or some Mikuni RS carbs won't take the bike off the road for very long and will let you have some fun over the summer while you decide what direction you want to go with it. I've rode a friend's bandit that had a holeshot 1216 kit and lumpy cams, fun bike but still a bandit at the end of the day. Before you dump a bunch of money on suspension, definitely look more into getting a slingshot or slabby frame. You can find bare frames in the states here on Eblag, but you're always going to be better off buying a full donor bike. Things like bodywork, controls, gas tank, will all add up pretty fast. I'm out in the PNW and also avoid facebook. Keep an eye on craigslist, stuff pops up from time to time. I don't know what it's like out there, but definitely check across the border up in Canada. For some reason out here, there's way more old GSXR stuff for sale across the border in Vancouver than there ever is in Oregon and Washington combined. I think Americans might have just done a better job of destroying GSXRs back in the day.

Any idea if the full K7 front end will fit in USD slingshot forks? I've got a Yosh top triple that I'm kinda fond of, but would prefer modern forks and brakes.

What part of the country are you in? With only 2500 miles and what were stock carbs, nothing should be worn out in them yet. Sounds like you're on the right track with the float levels, and just accept the fact that these engines like being revved out and were never really designed to be useful below 3K. As long as they idle well, no hanging idle or anything, and it doesn't stall when rolling around parking lots, they should be fine. All the real fun is up above 9K. The tachs on the 88/89 750s didn't even start until 3K. I've got a (US)92 750 with the same carbs, but they have a warn out dynojet kit in them and they run like shit below 5K. I was going to pull them and stick on a set of Mikuni RS36s, but I've got a spare 1127 engine, carbs, and exhaust, so I'll be going that route instead. Post up some photos of the bike, don't see a lot of super clean low mileage stock bikes around here.

Try giving Factory Pro a call or shoot them an email? They have a little bit of tuning info on their website. http://www.factorypro.com/Prod_Pages/prods06.html Also check your intake boots the next time you have the carbs on and the bike running. Just spray some starter fluid or similar around the intake boots and see if the throttle jumps. These bikes also don't have a ton of power below 3K, but you shouldn't be fouling plugs. How many miles on the bike? Usually the emulsion tubes are the first thing to wear out.

I ran a stock dual outlet slingshot 750 petcock with RS38s and it flowed plenty of fuel, eventually switched to a Pingel for the extra space as it was a 7/11 and to ditch the vacuum line off the number four intake boot.

I'm hopefully gonna be pulling an old 95 braced 750 swing arm out of an 1100M(?) frame over the weekend. Did the swap well over a decade ago, don't remember it being all that hard. I'll see how I managed to fit it all together as I don't recall buying anything for it. I do remember it making a world of difference in handling through fast turns compared to the stock swing arm.

Yeah, the J/K are definitely the smallest. I've got an N(US model) that I'm about to swap an 1100 into, and I'm pretty sure it's still smaller than the 1100 frames but it has always felt bigger than my K 7/11. I'll measure them in the next couple of days and report back.

That was only a slabside thing, all of the slingshot 750 frames had the removable frame rail.

I believe 90 was supposed to be the best of them, best 750 engine, USD forks, and none of the weight that 91 got. Though if you're just going by a bare frame, minus forks and swing arm, 88-91 are pretty similar. I can't remember how they tweaked the geometry over the 4 years they made them, but it wasn't much. The main difference between the 750 and 1100 is the height. Maybe an 1 1/2" taller with the 1100 frame to clear the taller engine. The 1100s also had longer swing arms. I've got an 89 750 based 7/11 with mid 00s suspension and with everything dialed in, it's pretty damn similar geometry wise to an 05 GSXR750. The only difference being the slingshot frame is 10mm longer than the more modern one.

Factory Pro also does a ton of shit talking about Dynojet all over their website. I used to live about an hour from Factory Pro and always used their jet kits because they were nearby, also preferred that they used factory Mikuni jet sizing, so it was easy to get spare jets if needed. Only recent experience I've had with dynojet was on the stock 38s on a GSXR750N, needles and emulsion tubes were totally shot, but no idea of the age.

Yup, I'd buy it just for that solo cowl. Those things are getting rare and pricey.

Thanks!

Got a link? I've got a 95W swingarm that I'm about to swap over and it's in need of some loving.

Years ago I rode a mate's MK1 with a 1216 kit and some lumpy cams. Great engine and a blast to ride, but it still looked like an old man's touring bike at the end of the day. I even prefer the MK1 looks over the MK2, but every time I even consider picking up a cheap one, I just can't bring myself to have to look at it every time I go out to the garage. 2006 was a crossover year. New bodywork but the engine was the same old lump that suzuki had been making for years. I'm sure suzuki figured out some way of saving some small amount of money on each bike by updating it over two years from oil to water.

Also I’ve had several old 750s with leaky boots and you have to drag the clutch when you stop to get the idle below 3K. Slight hang is most likely just jetting.

Sounded like a timing issue. Glad you got it sorted. It’s a hell of a lot warmer here in the PNW, but I’m still avoiding my garage until it gets warmer.

I’ve never mixed up rockers before so I have no idea. If you’ve been working on it all evening the best thing to do is probably leave it for the night. Try matching up 4 rockers that are in similar shape and throw them on the intake side and see what happens. Are you here in the states?
