I got a 1986 KH 125 K3 not long ago, & there is an electrical problem. When running, the front & back light work fine, but the indicators & horn are not, any suggestions? Cheers all.
The headlight and tail lights are a separate part of the electrical system that run off the generator, and will only work when the engine is running.
The indicators, horn, brake light and neutral indicator light run off the battery, so should work as soon as you switch the ignition on. If they don't work when the ignition is on, first check the simple stuff. Check battery connections, then check it for charge, check fuse. Check connections on horn, indicators etc and make sure they are not corroded. Check the switch gear because corrosion sometimes sets in. Spray WD40 into all your contacts. Remove the headlight unit and make sure all connections are in the right place.
Anybody know where I can get diagrams for putting the engine together, as my KH125-K6 came in bits?
Can anyone find me Kawasaki KH125 wiring diagram?
Hi, I've got a K6 KH125. My seal at the downpipe to muffler also needs replacing. Been looking everywhere for the part, but can't find it anywhere. As far as I'm aware, it's a rubber seal? Anyone know where I could purchase one?
Hello, I have a 1992 KH 125, and it can cruise at 60, and it will hit 70 to 75. That's not at full throttle, as I don't like to hear a bike scream.
Hi, I got a 1986 KH125 K3, and the poor little thing has been running very smoothly over the past year, but now I've got work and cash flow, it's time to whack its top end up a bit for motorway cruising (hate hearing bikes screaming their nuts off down the road).
I'm looking at a Gibson Allspeed exhaust as the first upgrade, then adjusting the carb jet size, which is where I fall into a pit of needing knowledge... what jet size would be good to go up to without going over the top? And what decent aftermarket air filter would be suitable for the jet size?
Is there anything else I could do to get more from the engine without having to do a complete strip-down and rebuild, since I'm using this bike everyday. So exhaust, carb, air filter, re-boring the barrel, porting and polishing are all I could think of at the moment...
Hi all. I've posted a few original brochures on my kh125.co.uk website, plus some other bits of information. All contributions welcome.
I have the exact same problem. When I got the bike, I bought a new battery. Everything was working fine, but I didn't use the bike for some time, and now the indicators and horn are not working, neither does the brake light. When I push the brake rear or front, the neutral green lamp dims. I tested the battery today, it shows 3.4 volts. When I start the engine, it goes up to 6.80. Fuse is fine. Could it be the battery in bad condition? Or what could it be?
Hi I have a KH125 K6 and my engine has just gone pop... bearings shredded everywhere, so a replacement is in order. Does anyone know of anywhere that I can get one cheap??? Or has anyone on here got one they no longer require?
Also, will any other Kawasaki engine fit in there?
One more thing... I have wiring diagrams for these bikes, and looking at older posts, it seems that some people needed them. I'll be happy to help if I can.
