Did you drain the carburettor bowls? if not then there maybe water in the bottom of them. you can usually drain them by unscrewing the phillips screw at the bottom of the carb bowl a couple of turns to let the liquid contents drain out. Turn the fuel petcock off to prevent fuel from coming out of the tank while doing this. When all the carbs have been drained, ensure that all the screws are tight and open the petcock and prime the carbs and go for a ride and see if there is any improvement.

Hi, Gothtec1 and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, stator, magneto, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Air/fuel mixture screw improperly adjusted.
11. Accelerator pump damaged or not working.
12. Water or dirt in the fuel system, carburetor or filter.
13. Restricted, blocked or kinked fuel line.
14. Fuel tank empty.
15. The gas cap is not venting properly or fuel tank venting system blocked, loosen gas cap and go for a test ride.
16. A failed fuel pump, pressure regulator and or fuel injectors.
17. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
18. Needle and seat stuck closed in the float bowl.
19. Petcock clogged or damaged.
20. Lean angle switch is faulty or needs adjustment.
21. Catastrophic engine failure, perform a compression test.

I have a 2004 gsxr1000 that will not start. I stored it through the winter.It started and ran good but had loss of power over 8000rpms but otherwise started and ran. I sat it for 2 days and now it wont...

The problem is that over the winter water tends to condense inside the fuel tank. If you did not replace all of the remaining fuel from the tank it might be contaminated with water.
Try to leave your bike with a full tank next time you live it unused for a long time.

Will not go above 4500 revs power loss, overheating.

It sounds as if the engine is running very lean, this can be caused by several things. Firstly the fuel filter you have installed, is it pointing in the correct direction (Fuel in and Fuel out), also is it a high pressure filter? If not remove it. Another thing that causes problems is the fuel pump could have a problem, it is also possible the gauze filter on it is clogged. Next check the fuel you have and make sure it has no water in it, to clear small amounts of water you can get a tank of ethanol, this will mix water and burn it off as you ride (Don't us a big mix E10 should be sufficient) if you don't like the ethanol, empty the tank of ethanol and refill with regular fuel.

My GSXR1000 K4 is running rich, smell of fuel. Any ideas? Thanks

Things to check: The air filter. Is it dirty or wet? Also, make sure there's nothing covering the intake to the air filter box. Then, check for sediment or moisture in the float bowls - which can cause the carburetors to overflow. The easiest way to do this is to drain the fuel from the float bowls using the drain screws and see what comes out.. Draining them may cure the problem, for now. If there's dirt, water, or rust in the carbs, then you'll want to check the fuel tank for signs of rust.

Not running properly,inconsistant ,revs up and down,and no range.

Could be the fuel - especially if it's been stored for awhile. LOTS of problems with Ethanol now, especially if you have a vented gas tank. The ethanol actually draws water (humidity) through the vent and into the tank... then the water and the ethanol settle to the bottom of the tank with the gas on top. Of course, your fuel pump draws fuel from the bottom of the tank. I use StarTron Enzyme Fuel Treatment, which seems to help.

Lack of power and low revs

Remove and clean the carbs. Remove and clean the fuel petcock water trap then put everything back together. Try the bike now.
If still bad then take it to the shop and ask for a compression check. You may have some burned valves.
