So with carbs your never going to get it perfect all the way through the rev range but should get it near enough.
The main jet 3/4 to full throttle
Needle/slide 1/4 to 3/4
And pilot jet and screw , idle to 1/4
Just a rough guide but there is a slight overlap . So if you reduce your mains by a measurable amount it will then have a slight affect say over half throttle .
As the previous replies the top end is rich you want to reduce the mains and then work from there .
From memory my bandit with pod filters and a full Akrapovic system was 150 mains .

Coils?
in Oil Cooled
I would also have check of the connectors in the loom and the main ground connection on the engine just to rule out . From what you describe I would say its carb problems tho.

Used a vac manifold on my bandit for 5 years , it's on carbs tho .Taking the pipes off where you would fit a carb balancer . 1 pipe to each port . No t peices .On my 7/11 turbo with gsxr 600 k1 tb's I have drilled and tapped the underside of each inlet port and fitted a small an-3 fitting .

Should be direct swap . 750 arm is 2 inches shorter . M / N have a wider mount where the linkages bolt on and you ideally use the matching rocker .

I've got set brand new ones, 18mm
You want 20mm for an oilcooled motor . Sounds like you have gen 2 pistons which wont work .

Shouldn't be too hard because I fitted bandit 12 wheels in my 1100wp years ago . Think it was just messing with a couple of spacers . Yes you are correct the caliper is located on a lug inside the arm.
-
Bandit 1200 rim is the same as the gsxr 1100 wheel except the wheel bearing on the disc side sits further out.
-
I've had a cylinder head sat in the loft for a while I purchased second hand that has been ported and skimmed . The inlet side has some titanium retainers fitted with different collets so the valve stem just sticks above the retainer . Is this going to be ok ? Valve springs look after market . Anyone seen something like this before ? No markings on the head .
-
For handling I would stick a 750 L or M ( depends which rocker you have ) swingarm in . The forks are going to be soft as oil cooled bikes are a lot heavier . I hope the clip ons are not above the the top yoke as those forks are shorter than the 1100 ones.
-
I would have a look and see if the cam chain is loose .

Clutch covers are interchangeable . Gasket is same part number .
The oil amount cast on the side changes between models .

Just drill the bottom rear engine mount to 12mm , everything will line up as before .
-
I would take the clutch cover off and check the clutch pressure plate Is lifting correctly . If it's been standing for a while take the plates out and make sure there not stuck together . Worth taking the clutch slave cylinder off and cleaning as there not in the best place and tend to get covered in crap.
I have had the friction plates break up so not worth the risk .
The wrong oil may cause it to slip but not drag .

Yes you are correct the front discs are different off set , you will either need to space the discs out or gsxr ones .
Pic of the spacers are all OE standard ones .
If running a bandit caliper hanger you wont be able to run the stock torque arm to the frame as the slingshot caliper hanger pivots and has a brass bush in .
-
@ChrisR1 pics attached .
Left hand side and right hand side of the 1990 750 L I have .
Also included pic of a gsxr slingshot wheel and a bandit 12 wheel as you can see the difference on the disc side .
99% sure the sprocket carriers are the same . The wheels are same sprocket side .
Last pic the spacers -
Sprocket carrier side @ 16.5mm
Disc side @ 21mm
Caliper hanger @ 29mm
You can fit bandit 12 wheels in a slingshot but its bit of massin about as the caliper hanger pivots around the bush in the centre .

Hey colinworth79 thanks for replying. Per my other reply it isn't the same - I have no idea where it is from originally!
Yes your correct , that spacer is 1200 bandit . If you need I can post some pics from my 750 L ?
-
Clip ons sit on top of the yoke on the 1100 and the forks are longer for this . You could get round this with some adjustable clip ons .
-
Slingshot fairings only change on the top and side panels .
Belly pans all the same..
Top fairings , 750 has 2 bolts on the side and 1100 have 3 and then match to the respective side panels .
The last slingshots M and N have a larger enclosed headlight instead of the 2 round lights . Again different between the 750 and 1100.
-
The space in the top pic is for the brake side. To go between the caliper hanger and wheel .
-
Possibly need to remove to get the crankcase bolt out ( left one in pic )
Yes they always round off as there made of cheese .
I normally get a chisel and put a notch in it then tap it round .

There is several things you can have a look at to try to eliminate the problem.
As stated the fuel pressure has to be set to 1 - 2 psi at idle otherwise the carbs will flood.
The return line back to the tank needs to be at least as big if not bigger than the supply .
Make sure you haven't got dyno jet springs in the carbs as there weaker than stock .
Have you got a dump valve fitted ? If not I would fit one .
As regard to jet sizes , the size and design of the pitot tube to the area of the boost pipe will have an affect on the size of main jet you run . Too small a pitot tube you end up with massive main jets. There was a really good article on line somewhere about this.
I would get some afr readings as possibly it's going really rich once you snap the throttle shut.

My bandit (1340 turbo ) has a couple of pipes off the clutch cover and one off the cam cover box that then go to a catch tank under the seat . There is a bit of smoke come out when the engine has been used hard and is hot .

normally just have a round tube coming off the plenum and then the hose takes up the slight difference in shape . i assemble the pair together on the bench then fit to the engine as one unit .

Bov need to see vacuum to work so off carb tops .
Fuel pressure reg either plenum or carb tops .
Gauge depends on what you have if it has vac then carb tops.
I make a small manifold that links all 4 carb tops then took items off this to give a smoother reading.
