I have a kawasaki zx9r 1995 it keeps overheating i have gone throught the coling system completely and everthing is perfect if the bike is standing it doesnt overheat but as soon as im drving it heats up fast the carb has just been rebuilt about 5 months ago does it just need a tune up?

make sure that the thermostat is working and opening to let the flow of water in the engine, if it's ok you should start it and let it warm up and see if the cooling fan starts when temperature reaches close to 98 degrees, is it doesn't and the coolant boils then you have to change the temperature sensor as it is faulty.

Drain fuel Remove lines replace if needed Remove bolts to pump with out braking Clean around where gasket goes Check for dirt particles Install new pump Hook up lines and get riding again

THOUGHT YOUR BIKE IS AIR COOLED

Go here and download a shop manual. It's the first thing I do before I work on any bike. Then I burn a copy of it on a CD and give it to the customer.http://www.tradebit.com/G/manuals/9-motorcycle

HAVE YOU CHANGED THE PLUGS AS A FIRST STEP

you either have a severe missfire or its running too rich if it iworse when riding the bike and you do a rapid gear change to a lower gear and it pops and bangs a lot its air being sucked into the exhaust system from a leak in the exhaust joint or gasket failure check for blows around the exhaust clollectors or splits around the bracket that holds the pipe on to the bike frame

get some bike stands or do one wheel at a time but make sure u have some tie downs

Hi smithydean
First just to make sure do a mutimeter test across your battery with the bike running should be around 13.5 volts, 14 would be suspect (check you manual), If ok and the is no looseness around the light body it may be as simple as changing the brand of bulb to a better named brand, I have gone through 2 of these in the last couple of months myself. Stay away from cheap globes mate they don't stand up to vibration and jaring delivered by sports bikes.

let it dry out and kick it over a few times with the plug out. it should start fine when dry.

Readjust the carbs.The bike has lean mixture (too much air).Check your spark plug's electrode color.It must be dark brown.Neither black nor white.
