My older kx 65 was running like an animal but suddenly staring backfiring and no power when throttling up. Idles fine but cannot give it any gas . Any suggestions. What is the correct fuel /oilmix , I have been running 40:1.

Sounds Like A Spark Problem to me Or probable your Fly wheel throwing off your timing..
Usually if she is Back firing Ignition Is usually the culprit.

hope this helps.

Hey Nuvo, this website is about motorized bicycles! not dirt bikes!

Why not introduce yourself in the into section, so we can say hi.
