Not sure with the G engines, but double check that the cam sprockets match, you might need to swap the G sprockets on to the F cams. Usually people swap the dot heads onto bandit engines and those need the bandit sprockets.

I'd go with the 750F cams. If they end up being too peaky, swap the G cams back in and you should get back more bottom end. R cams would kill all of the mid range you're currently enjoying.

Water cooled and slingshot arms are pretty interchangeable, just the pivot diameter is larger on the Ws. If you had a 750 slingshot swing arm mocked up, a W will be the same. The braced 750W swing arms are a nice upgrade on the slingshots, and are as simple as just sliding the slingshot spacers inside the W spacers inside the bearings. I've never worked with the 1100Ws, but I've used a braced 750W swing arm in an 1100M frame.
This is an 1100 with a 750W swing arm in it, and it is on the short side.

Those cam caps look worn to me , I wonder if he had oil .
It's a 2 1/2 year old thread. They're not even active on the forum anymore.

Remembered a friend's gf has one of these. Forwarded it on to her for a parts bike. Just hate seeing old Suzukis wasting away in a barn.

It's a 450 twin, isn't it?
Yup, looked it up and it matches. I'll probably pass on it then, I have too many other projects and not enough space as it is...though I did just look and seats are easy to find on Eblag for it. I just don't know what I'd do with it other than use it for a little "bar hopper" around town. If anyone else is interested in it, I can give you the link for it here in Oregon.

I'm currently out in the country dealing with a parent with dementia and I noticed this Suzuki for sale pretty cheap near by. I'm an oil cooled guy that's only ever experimented as far as buying water cooled GSXRs to strip them for parts. So other than the ad saying it's a 70s bike with keys or a title, I have no idea what it is.
It's really cheap and they're open to negotiating on the price, sounds like they just want it gone. Any idea what model/size it is? Looks like the tank is dented, it's missing the seat, side covers, and the sprocket cover. Is the shifter mounted on the sprocket cover as well? Just wondering if it would be worth doing anything with it or should I ignore it and go back to focusing on my other projects that I've been neglecting? Thanks, and the odometer shows just shy of 20K miles.

In the docs i have, 88-89 7R, powerscreen and 1127R have 8.8 and 8.2 lift, however i don't have all the duration values and obviously that changes things.
If they smoothed out the part numbers and if the duration made the 7R nicer, maybe they unified it based on the lift values alone ?
Or maybe the docs i've had are wrong ?
The online parts site I use here lists the J and K as different part numbers, with the J fitting lots and unavailable, while the K only fits a couple years of 750s/1100s and is available. But who knows what suzuki has done in the past 30 years with replacement parts on these engines.
-
I'm pretty sure that starter gear is supposed to have a little play in it. @fatblokeonbanditwould probably know better. Bike looks pretty clean without the plastics otherwise.

Both same part numbers as powderscreams and also all the 1127 GSXR 4 cam camshafts
Now days they are, pretty sure they were different when new. I've gone through all of the cam part numbers as well, and I think as some point Suzuki decided it was cheaper to only make a limited number of replacement cams as they're all interchange in the tappet heads. I'll double check my old factory manual at some point and see if it lists the different cam part numbers for the various 750s.

Looking to sell
In that case, they're horrible engines and I'll take it off your hands for 50 quid, including shipping to the states. Cheers!
Really depends on condition, how's compression, how do the cams look, obvious crash damage, etc. In good condition and good compression I usually see them for about $500 here on the west coast of the US, but they don't pop up too often anymore.

There's usually a bit of play in that starter gear. Congratulations on the blandit. If you can get the engine sorted, I'm sure the rest of the parts you can find cheaply from someone else parting one after they've pulled the engine for another project.
The alternator nut is usually hit with a punch on the edge of the exposed threads to lock it in place. I'd advise doing that again with the new one. You should be able to see marks on the old one and on the shaft.
Aftermarket oil coolers are pretty cheap if you can fabricate up a bracket for it, or find a used stock one.
Now post up some photos, we like to see photos of bikes here.

As far as I could tell while standing over the bike and measuring, about 38cm.

Can't do dyno either. Nobody offers dyno carburetor set up in the country i live in
I've got the same problem where I'm at. Hand full of shops around with dynos, but if they can't tune your bike with a computer, they don't even want to talk to you.
-
When I get home later today I'll measure the one on my 750n, it'll be close, but not stock. My front end is lowered and not sure if the rear ride height has ever been adjusted.

I saw that you wrote that but unfortunately i'm going to have to stick with the singles on this bike
If you have to use singles, it seems like the foam filters with the air box rubbers works better. Either way it'll probably need an afternoon on the dyno to get sorted.

Currently trying to set up my 1127R engine with BST34
I have KN single pods and the exact same exhaust as you, currently on 140 mains, 3 turns and middle notch needles, it's sluggish when you try to give it beans, so sounds like i need to up the game ?
Dual pods will make it run a lot better.

Thanks everyone for all the tips. You’ve confirmed some things for me and given me some good stuff to look out for.
im going to have a look at the bike this weekend and I’ll let you all know how it goes. Hopefully I’ll have a new bike in my garage come Monday
We like photos here, so do post up some if you buy it.
Also check for oil leaks around the two oil return tubes on the front of the cylinder block. If they did a cheap rebuild and skipped replacing the o-rings on them, they will leak and need the head pulled back off.

yeah thats what I heard, but my thinking was using single sponge filters on each of the airbox rubbers would seal better than one sponge filter across 2 airbox rubbers and leaving a gap between them, if that makes sense !!!!!!
saying that it seems to work.
The ram air filters flow a lot better than the K&Ns and the airbox rubbers probably help too. I still use K&Ns with CV carbs, but I use dual ram air with velocity stacks on flat slides.

I really wish we got these in the states.

Search around online, plenty of Suzuki factory manuals out there. If you mainly need it for the engine, the GSXF750 manual should be pretty close.

I've been seeing an uptick in people on the internet claiming that you need an air box to get maximum HP out of these old GSXR engines lately, especially over on facebook. If that was true, all of the old racers would have kept the air boxes. Fuel injected bikes, thumpers, bikes with ram air and down draft carbs, yeah they need air boxes. Bandits and GSXRs are mostly fine without them.
You want the dual pod filters, don't use the singles. Explanation I heard years ago was the dual pods give more standing air for the carbs to draw from, lets them breath a little better. Whether that's actually true or not, who knows, it's just what I was told and has been my experience with individual pods ever since.
Most of the stock bandit/gsxr carbs work great without an airbox, the BST40s being the exception. Just extremely hard to tune with pods.
A jet kit from DynoJet or FactoryPro will get you pretty close to where you want to be, a dyno will always get it the rest of the way.

Reciepts for parts or work done. Without that Id assume the motor probably needs a rebuild. Seen too many people get caught out by the just been rebuilt lie.
Looked at a Mini years ago and the owner was adamant the motor was 100% rebuilt. After a lot of questions he finally admitted that he had "checked over the motor" and replaced the tappet cover gasket.
This! I don't even trust hand written receipts anymore. Unless they're printed receipts from a legitimate shop, they don't mean shit.

Hearing it run is always a good start. Test ride it and see how the transmission and clutch feel.

Big bore?
in Oil Cooled

You could always swap out the stock oil cooler for one a bit larger. The GSXRs always came with larger coolers than the bandits.
