I have a 1995 Kawasaki KLF300C 4x4 which is going through plugs like mad, i can probably start is 9 times before the spark goes orange and weak and won't start, put a new plug in it and fires straight up. Any ideas where my problem lies?
She is running rich as she is blackening the plugs, but the carb is correctly jetted, brand new air filter and new spring in the carb, there is no adjustment on the carb which is annoying! Any ideas how to make her leaner?
If your fuel cutoff valve is working just don't turn it all the way on. This will slow the flow of fuel coming in. Or you have to decrease jet size, or increase air flow in. Is the filter a high flow? Is there anything blocking the holes in the breather box?
The fuel tap does work but I've tried limiting the fuel and it hasn't made a difference. It's had a new Kawasaki air filter element with spark arrestor in it about 2 hours ago, I will check the air box openings but I'm sure they are ok, it's got a 125 and 38 jet in it, what would be the jets to buy to make it leaner?
