    thanxs for the ideas guys but it was a small stupid fault on my side, die vacuum pipe on the carbs was connected to the what I guess would be the overflow on the tank and not the tap resulting in not getting any fuel to flow out, you know how it goes when you're in a hurry, everything goes wrong, thanx anyway

The slingshot does NOT have a fuel pump. It is gravity feed through a petcock. Make sure that the petcock is set to the ON position. Its under the tank on the side.
If your bike has K&N filters on the carbs make sure you cover them with a plastic back before you wash next you will have to wash them and re-oil them before you put them back on. Dont use super high pressure washer to wash your bike. A garden hose will do.
If it has the stock air filter you might have gotten water into the carboration system with that high pressure washer you used. You'll need to disassemble the airfilter unit and either remove your carbs to take off the float bowls and get the water out or try to drain your float bowls while the carbs are still on the bike. Siphon out all the old gas if you think you got water in it or you will have to do this all over again. Sounds like you intoduce water into the system to me.
1. Got good gas?
2. Got spark?
3. Got oxygen?
4. Got rid of water in the system? = Should start.
I use to own a sling shot too. 1988 model red and white.

If you have a spark ,remove fuel pipe from bottom of carb , if fuel is present then the problem may be blocked carbs (common after a respray ). if fuel is not present the n the filter will be blocked in the fuel tap just remove and clean hope this helps

Strange fuel pump issue on FXCW.

High pressure feed from the pump in the tank is rubber and the E20 fuel damages the rubber making it porous so pressure cannot build up to supply the injectors.

The bike had stood unused for 3 years. Had the tank cleaned (rust) and changed the device that channels fuel out of the tank. The bike (2007 Grand King 125) starts and cuts off after a few revs.

Sounds like you have to pull down the carburetor and thoroughly clean it. Over the years the bike did not started debris and calcium deposit might have blocked the air/fuel jets.
Clean it and soaked the carbruretor for a day with lacquer thinner, so that all the air/fuel passages will be clean out. A high pressure air will help the clean up!
Thanks for using FixYa!

Hi and welcome to FixYa,

Initially, check color of sparkplug tips to determine if lean or rich air/fuel mix. Offhand I am inclined to think lean (light brown to almost whitish)l if yes then possibly:
  • an air leak on the rubber coupling from the air cleaner enclosure/box;
  • the needles may have to be raised a bit by inserting thin small washers.

Postback results of above checks.

Good luck and thank you for asking FixYa.

If ur problem is that the bike is not getting any kind of sputter or fire when you turn it over then 2 things...
1st is easier, alot of bikes even when their battery shows its ok, it may not be you can tell by hooking up a booster (a jump) when starting and this can be a major problem with a little fix
2nd suggestion which I have had to do on many bikes (which Is why I suggest the easier of the two first) can be a real pain in the ****, you have to pull your tank if it does have a fuel pump this is where you will find it, if there is one you will have to pull it apart very carefully and clean it with an air hose to get all of the grime out and then carefully put it all back together...also you should go ahead and get some carburator cleaner and flush out the fuel lines, fuel filter, and then the carburators...
...if indeed you have a problem with the fuel this should fix it...sounds to me like u may have a slight problem with both
