I have a 1989 yz80 that wont start, it has compression and will turn over but wont run any help?
The problem that might be causing your 1989 YZ80 not to start include, having bad spark plugs or wrong installation of the kick starter. You need to check the spark plugs and ensure that the kick starter is installed correctly.
Compression was tested so it...Carburetor rebuild kit needed? Spray starting ether?Ignition system or timing? No spark?
