SOURCE: 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.

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.

1990 suzuki gsxr

So have the shop fix the petcock or just buy a different one complete. Google " motorcycle salvage suzuki " and you should be able to find one there. While you are waiting for the new petcock, go to the site below and download a free service manual for your bike.

What is the best carb set for this year gsxr

Pull out the slide then lower the clip on the jet needle one notch. Then try two notches. This will richen the mid range response. Give this a try before trashing the carbs.

Go to the site below and you can download a free service manual PDF. The one you want is 47th from the top of the Suzuki list. Yes, I know that it is for '93 to '95 models. It is the closest I could come to '89 and 90% of the data doesn't change and it is free. For an exact match Google " service manuals suzuki " or go to www.repairmanuals.com
Also try your local library. Often guys will donate manuals to the library.

GSXR 750 Slingshot wont rev past 5000rpm, with or without choke

I have seen this before a few things to do too make sure. First take the air filter out and shine a light use your fingers to move the slides up and down I suspect the springs that go on the slide is not seated in center you can tell from the slide going halfway and hanging up. Next, the boots on the slides only go on 1 way there is a notch on the carbs for them. I would guess this would fix you up if not we can get deeper into it with air-fuel mix screw settings.good luck
