06 gasgas mc65 stator ohms

Check the ignition/ switch.

also, does it have an immobiliser.?

I would first suspect the stator. you need to have an ohm meter and ohm out the stator when it is warm...its possible for the cdi to be bad but not typically when it heats.

Sounds like you have a bad stator. It may be producing enough spark to start the motor, but under a load (as in the water) it simply can not supply the amount of spark needed. Sometimes when a stator is tested on a ohms meter it may test good, but still be defective do to the load it will come in contact with when put in the water.

You must first disconnect ALL the stator wires to prevent a bad reading. You MUST have a good meter, cheap ones will not do. Put the meter on Ohms and put the probes together, note reading (this is the resisitance of the meter wires and this reading will need deductiong from the test readings). You will need a service manual to know what that actual values should be at what ambient temp. They are normally very low less than 1 ohm so cheap meters won't read. Check each wire with one lead and the other to the stator metal ground. You should have ZERO any value here is a short. Then check between each pair and read the value (many stators have multi windings T1,T2, Q1 Q2, B1 B2 etc, so you need to make sure you measure across each pair.. Generally values are 1 ohm or less

Check the on/off switch for corrosion.Cleanit and use dielectric grease on it. If this still doesnt help,then check the stator and make sure the keyway key hasnt sheared off. If it hasnt,then do a stator test on the stator to make sure the stator is good.
Good Luck!

If you had your meter in AC VOLTS, and you only got three volts out of the stator, it's bad. Check for a shorted stator but putting your meter in OHMS R X 1. Put one probe on the engine case and then the other to one of the contacts and then to the other. You should read infinite ohms. 12.5 volts is the normal reading of a fully charged battery. I never do the shorted stator test. Why? If the stator is not putting out at least 30 volts at a high idle, it makes no difference if the stator is shorted or what, it needs replacing. That's the way I look at it.

Good Luck

have you checked the spark plug caps, if they read above or below 5000 ohms replace them. If they are good then the news is bad. You could have a bad cdi box but more likely with this model , you have bad pulsar pick ups, which unfortunately are part of the alternator assembly. These can be checked without removing the engine by taking readings from the plug going to the cdi box. ac generator disconnect the stator wires at their connections. X10omega
white-blue 77-95 ohms
green-white 387-473 ohms
orange-green 95-116 ohms
light blue-green 95-116 ohms
orange/red-green 81-99 ohms
light blue/red-green 81-99 ohms

advance pulsar

orange/white-green 185-225 ohms
light blue/white-green 185-225 ohms

magneto stator can also be a solution check for AC power from stator while cranking the motor use sta-bil winterizing fluid to insure piston where during cranking process spray directly into spak plug holes with spark plus out 4 sprays into each cylinder should be enough crank motor without plugs for reduced compression and more cranking amps

If it ran before, I would double check your electrical connections. Its more likely you didn't get a connector pushed all the way together or left off a ground wire. The ignition coil specs are generally 1 ohm or less on the primary (small Wire) side, and 5K-10K ohms on the secondary (spark plug) side. Each side should be tested to ground. Pick-up coils are typically open or really large ohm reading in Megaohms normally and around 100 ohms when the magnet on the flywheel passes by. there is no way to test the CDI box other than putting it on a know running bike or getting a known good CDI and putting it on your bike. Double check that the spark plug cap is secured to the high tension lead as well. Testing the stator is a little more complicated, but a quick way is to close the gap on an old spark plug to about 0.010" and see if there is a week spark. If so, the stator will need to be replaced.

The side stand kill switch can go bad and do this. Check the switch with an Ohm meter. Also, check the wiring harness connections. Fix any loose connections. Check the handlebar kill switch. It can go bad also.
