Won't start when hot or warm...

I have a 98 ZX6R...When the temp gauge gets 3 or more bars and I turn the bike off, it won't crank until it has 2 or less...Any help would be appreciated...

the torque converter is probably locked up.



could be your coils. how many miles do you have?

check your coils with an ohmmeter to verify there is some resistance and that the resistance is similar across all the coils.

if that shows good, then fire up the bike with one plug out at a time and see if you get good spark with the plug on the wire. obvious caution should be taken here or any time your messing with high current electrics. repeat this when it's hot and won't start.

the other source could be the ignitor that times the ignition pulses.

do you have a service manual for your bike? sometimes you can find them posted online. after i bought one for my zr7, i found a downloadable version. it's good to have both.

The good thing is that there are only three things that could be wrong. First off there could be no fuel getting to the cylinders or too much that it's flooded. Second, there's no spark, and third, the compression is low.

With your low mileage, we'll assume the compression is good. Like tonered said, you have to check the spark when the engine won't start. Of course, when the engine is screaming hot it isn't a good time to try and pull out a spark plug. I would bring a good plug (any kind) and pull a spark plug wire and test no. 1 or 4 spark plug wire. Then I would do no. 2 or 3 plug wire (they use different coils).

If both 3 and 4 have spark (or 1 and 2), you have a fuel problem (filter, pump, float, float needle/seat, etc.). If you have good spark, I would pull no. 1 spark plug to see if it is wet with gas. If only one cylinder has spark, you have a coil or connector problem. If both don't fire, you probably have a bad safety connection (kickstand, neutral, clutch, etc.).
