How to remove fuel tank 1990 suzuki gsxr750
Remove the riders seat and you'll see two bolts at the back of the tank...each side panel will need to be unclipped as they attach to the tank also.
Once done, the tank should be able to be slid backwards and lifted...just be careful of the fuel lines etc
Hello there im rebuilding a gsxr 750 slingshot

GSXR 750 Slingshot does not start
best way to do this is to take spark plugs out individually and check for smell and sight of fuel. if it is getting fuel but not sparking then you will have a wet sparkplug. if it is dry look at the colour of the hook at the bottom of the plugs. brown plugs means running too rich, grey plugs means average burning and working well. black plugs is very bad and must be serviced. if all this not working the other test you can try but dont spill any petrol before you do this. if while you have plug out(only one at a tim or yuoll loose where wot leasd went to where) plugging it into the cable and holding with a very insulated pair of pliers, then try to turn bike over(start) whilst looking at the hook bit on the plug. if you see a bright spark from the plug then you will prob find they firing in the worng order. this could be a problem and should be dealt with by a dealer.
I have a 89 suzuki gsxr 750,it fires but will not
Clean the air filter and, if you have one, remove the water trap bowl on the fuel petcock and clean it. How good is the battery? Install new STOCK plugs. Bear in mind it may be time for carb kits. Other than your cleaning the carbs, the carb kits and balancing and synchronizing of the carbs are best left for the shop to do.
Check the exhaust pipes. If there is a restriction in the burned gases exiting the tailpipe then the bike will not run right, will loose power and even die if too much back pressure builds up. Disconnect the exhaust system and tick off the neighbors with a quick ride around the block without a muffler. If the engine still dies then exhaust is not likely to be the problem.
Check the compression on all cylinders. Depending on the compression, the bike may be ready for a valve job. If you pull the head for the valve job then you might as well consider re-boring the cylinders and install new pistons and rings. Bear in mind, doing a valve job and / or pistons is not recommended for the novice. The good part is that when the work is finished you will effectively have a new engine.

Were is the rectifier at on a 750 gsxr 1990
Under the rear cowl, right side. You don't have to remove it all the way,but you do need to take all the bolts out to move it so you can access the voltage regulator and the plug/connector.
This is where mine was located. it has 2 bolts attached to the frame, i use a 10 mm socket to remove and replace it.
Should only take approx 1/2 hour or less from start to finish.
I had a 93' 750 and i miss it now.
love those older **** rockets.

Just stated to run bad
You should take off the carb and clean it with petrol and compressed air, after that try replacing the spark wich is @ the carb.
Hi guys ...please help ...... i removed my plug
It goes to the coil of course but it is more than likely made into the coil and cannot be r replaced with replacing the coil. Call the Suzuki dealer and try to buy just the coil wire.
Good Luck
