1986 Kawasaki KH125
Hi, I have just been given a KH125 by a friend.
It broke down a few months ago. The problem is that there is no spark. The HT lead seems fine and I have tried a new spark plug, but still no luck. Any suggestion would be appreciated, thanks.
I had a go on this bike when it was running, and it felt a bit different to my KTM, but I fell in love with it. This is a very fun bike to ride around town on, and this is the first problem with the bike in 3 years.
Would you buy another motorcycle from this manufacturer? Don't Know

You just need a new battery.

Thanks for the suggestion, but still no luck. Any other ideas? I can't wait to get it back on the road and have some fun.

Hello. I had a KH125 many years ago as my first bike and wish I had kept it (reg: G499KMS). I miss it so much.
Anyway, regarding your no spark, forget a new battery, the bike will start even with a flat battery because the ignition runs off the generator.
If yours has points ignition (my one did), renew the points as they do get pitted, and as a worthwhile measure, renew the condenser. Prior to this, check all connections, especially at the ignition switch, ignition coil and generator. After this, the bike should start and run fine. Good luck.

Have you got compression?

There is a leakage coming from my exhaust every time I try to kick start the KH125 K6 rotary valve engine. When I stop kicking, the leakage eventually stops.
I cleaned the carburetor and fitted a new spark plug, and the leakage isn't happening due to those components.
I am wondering if it could be the exhaust valve or perhaps something else?
If it is the exhaust valve, how would I go about fixing it?
