I HAVE A 05 II00 CUSTOM HAD CARBS CLEANED BUT STILL HAS SPELLS SPITING AND GOING DEAD SEEMS TO BE WORSE AFTER SEATING FOR 15 OR 20 MIN AND ACTS LIKE ENG DONT WONT TO TURN OVER WHEN YOU TRY TO RESTART

Sounds like not getting petrol, clean petrol tap to get a good flow and clean and strip carburetor the needle and seat could be clogged any way clean and blow out jets and holes with compressed air put back together and away you go.

I would try using some solvent to clean the carb. It sounds like the float valve is not moving freely, therefore not letting enough fuel into the carb. Be careful though, solvent can be a bit rough on the engine, so be sure to drain it out of the fuel bowl and replace with the appropriate fuel before starting the engine.

Hi sndlys,
When the engine surges (we call it hunting) like that it usually means, the carburetor or the governor need adjustment. You have cleaned the carb. but did you clean or replace the air filter, and did you try to adjust the carb? Since it was running good before I doubt it is the governor. Try to adjust the high speed mixture screw by 1/8 turn at a time and waiting a few seconds to let that adjustment work it's way in the carb. Start by turning the screw out (counterclockwise) a few times. If nothing happens or gets worse turn the screw in (clockwise) a few times, but do not go less than 1 turn out from a lightly seated position. (turned clockwise until lightly seated so no damage is done to the seat or the needle screw) to prevent running in too lean a mixture to prevent overheating and possible engine damage. You could try the low (idle) speed mixture screw adjust a bit, but make sure you remember the position you started from whenever you any adjustment at all. I think if the carburetor is clean and the air filter is clean, also that there is a good fuel flow to the carb. you should be OK. I hope this helps out a bit.Get back to me if you need help. All the best and good luck. Denis.

Try changing your fuel filter

Tank filter not blocked? (Take tap off tank) Enough oil in motor? Try overfilling it slightly

How is temp sensor?

if gas is in the oil the needle and seat in the carb are bad or some thing in it. the gas will go in to the crank case and load the cylinder with gas. you can take the carb apart to see if something is in the seat. or replace the carb

it sounds to me like the carb float levels are out of adjustment and it is overfilling the bowls,or,the needle valve seats are worn and leaking,which will allow fuel to continue filling the bowls even though it looks like they are closed,remove the carbs from the bike,remove the bowls,turn the cabs upside down close the floats(push them right to the top,this simulates full bowls)then blow throgh the fuel inlet pipe,if you can hear air escaping from around the seats they are faulty,also check that the seats themselves are tight in the carb body,i dont know why but gsxr carbs seem to shake the valve seats loose..hope this helps

could be the thermostat stuck closed not leting water circulate to cool,,or could be the radiator fans not working too....
