How do i drain the carbs on my 1995 600zxr ninja........?help

If it sat for a while that could be your problem with the carbs. Its what it sounds like to me. How long was it sitting before you got it? It could also be that your air fuel ratio is off.

If condensation in the gas tank makes it into the carbs, the float bowls will trap the water. Too much water and the bike will act as you have described. Drain the carb float bowls. With a little luck you will be back on the road.

Drain all the fuel and put super high test in it, look for cracks or any leaks from the heads and cylinder walls

how's the plug look, float could be stuck, or hieght not set correctly. tab on float is bent leaving the fuel needle open slightly, or check synchroization of all 4 carbs and the choke linkage to all 4 carbs. choke could be full or partially turned on for that carbs .
good luck

Hi and welcome to FixYa,

If after the "...start with direct feed or starter fliud...", the bike will idle / run correctly, then it is not a carb problem. If will not idle / run correctly, then a carb problem.

Initially, it would appear that the problem would be restricted fuel flow from the tank through the petc0ck (fuelcut off valve). A way to check is to drain carb bowls individually, compare quantity and quality of fuel from each. Guesstimate if the collected / drained fuel is about right for the bowl size.

If on the otherhand, it is a carb issue (float closing early hence too little fuel in the bowl), then a carb pulldown maybe required. The illustration here would give you an exploded parts diagram.

This CV carb tuning procedures may interest you.

Good luck and thank you for asking FixYa.

hi there i think your jets are blocked in the carbs , need to strip the carb and cleen the jets and the bowl ect.. hope this helps

ok i have one and i just fixed mine you need to drain the fuel from bottom of carbs and drain the tank also. then replace the spark plugs once you do that add new fuel in tank and drain the carbs again unitil good fule start runing out then shut them off. aftre that make sure there are two line connected to the petcock from the carb. spray soem starting fluid in the air box and chock it boom it will start. if it has spark.

chris

there should be a screw head at the bottom of the carb bowl. undo this and it should flow through.

Hi and welcome to FixYa,

Your post "engine will not turn start", are you referring to the starter motor not turning or is it cranking but will not run?

• if no crank, check the starter relay;
• will not run, verify that there is spark at the end of the plugs;
• will not tun, verify that there is fuel in the bowl of the carb (drain again);
• if it has a fuel valve, set to PRI.

Incidentally, any clicking sound when you press START? Pls postback updates.

Good luck and thank you for using FixYa.
