Hi all

I bought a running KMX for 325 and after looking on eBay at prices it was a steal. It was very tatty and needs some serious tlc but I've taken it on as a project.

I did a carb clean and spark plug change for good measure recently after a few months of me just using it for fun around fields. Before I cleaned the carb the bike was running.

I changed the spark plug first before the carb clean and with the new spark plug from cold it started first kick.

After cleaning th carb and reinstalling It the Bike wouldn't start so I took the spark plug out and tested it by grounding it to the frame and got no spark. I am stuck on what to do having no experience in electrics on a bike. After some research I got a multimeter and tested the ignition coil and didn't get any reading. Saying that I have no idea if I tested it correctly.

I stripped the electrical tape to see if it was moisture on the wires causing them to short but saw nothing.

Need some pointers to carry forward. thanks [/url]

Check all the safety switches which can prevent the bike from starting.

Hi

On a Kawasaki of that age the first thing to check is probably the side stand cutout switch, or if bypassed / removed that it is still bypassed correctly

All the best

The side stand switch has been removed, and was running previously before taking the carb out. I will check it and see if there are any bypass issues but it seems unlikely.

I had to move cables out of the way to remove the carb.

Would there be anything in the alternator which I should look at which could be causing an issue?

If you could send me a link to a good one to use as all the ones i have found are electric start, when testing I did crank the kick start but no reading.

The spark cap looks aesthetically in good condition, no reason why it should not be working.
