The GSX 750 was a pretty well set up bike - not favoured by some on here because of the crank but they're only jealous really :-\\\.
There's not a lot you can do cheaply or dead easy - even messing with the intake is a real b*gger on your bike without any significant gains.
If I were you I would spend my efforts first on the suspension and the brakes - plenty of mods you can do there easily and without robbing a bank and it'll make the bike a whole lot easier to use quicker.
Failing that stick in an 1100 motor - that's probably the easiest and cheapest route.

The age old question....
How much money you got?
Not much....
Make sure that Marshall is pretty free flowing, swap the airbox for pods, jet accordingly, make sure valves properly adjusted, etc...
cost a few hundred bucks
A lot....
Bore it to the max (not sure what that is on that bike), get the crank welded, get performance cams, dump all the extra weight (center stand, etc...)
A couple thousand bucks.

It's not a roller crank and as they are the weak point of the bike (in the view of some GSR members) I wouldn't go lumping loads on the top end. ?250 will buy a respectable GSX1100 motor over here - waaay cheaper way of doing things.

No doubt, My neck of the woods, they don't seem to pop up that cheap very often. Hell if you get an 1100 motor, then it really IS "how fast do you want to go", because you can build that into a damn fast bike.

Get a K&N for the stock airbox and leave the lid off, or get pods. '83 1100 cams have more lift and duration.

Pods
Pods
Just for the record you get no real gain with pods you tend to actually lose perfomance. This is backed up by many here on the forums in other threads. If you want to mod your in take. I would suggest getting rid of the second air box if you have a second one like the 1100e's do and put a cone filter on there. Then you get the flow of pods with out the draw backs because they all pull from your first box. Keep in mind you will need to rejet your carbs. Good luck

I'm all for the 1100 swap.
Yes, one can go into all the full out modifications. Loose the weight of the bike in the right areas. Put $1000's into it.
Or, just.....
Put the engine on a skateboard. :lol:
But, honestly.
What sprockets do you have currently on the front and rear?
Cheap and easy, change up the sprockets.
1 Down 2 Up from OEM. One tooth down on the front sprocket, and two teeth up on the rear sprocket.
If you don't care about speeds over 160 km an hour, it should give it that feel of quicker and faster.

Is not 14 tooth in front the lowest sprocket on GSX 750 Es -83?
I dont think i can get a 13 t sprocket.

Yes, go with the bigger rear sprocket. Slightly bigger smoothbores (34's) and cams help alot.

i've heard somewhere on this forum
that you can only gear up/down a bike to a point. After that point, the motor just can't take it and you might lose a couple mph's
some words of advice

No, nothing like a 10-12 tooth change.
Sprocket ratios have their limits.
Yes, too tall, large front/small rear to a point it will not fit, and going too tall there is a point that the top gears will not even reach redline.
Ray is correct on the small front though, the radius is smaller, and additional wear will occur.
Z1 carries a 13t front, if you want a 12t check Sprocket specialists, or it may have been JT.
Too big on the rear, if one wants to keep the OEM chain guard 2 or 3 teeth would be close. From there either ditch the chain guard or modify it.
Here locally I can get a huge rear if I wanted from PMP Sprockets, but not really into becoming a "Wheelie King".
You could try to locate a US 85' 700E engine, and get the cams pistons and head. That might not be too costly.
