Hello Everyone, My spark plug is the one that came with my motor about 20 months ago. My bicycle had gotten hard to crank. I am unable to find a plug that will work. My CDL Unit will only take a plug that has no cap. A regular plug is to large to fit in there. My question(s) are, Can I buy a different CDL that will work? If so, Please tell me where. Also Where can I find a plug with a removable cap?
My motor is an F50 China, or Japan engine. Pedal start. I ride the hound out of that thing, and for a week I've been stuck at home. Please help me. Thank You.

Well you could go to an auto store and ask for an NGK plug or a hardware store. What I did was replace the cable itself (the cable un-screws) and then you would be able to use a regular spark plug. Hope this helps.

You can buy a much better B5HS or B6HS NGK spark plug.
You can buy a much better spark plug wire. As mentioned the spark plug wire itself easily unthreads from the CDI unit. New wire threads right in.

Thank You ~macaddict~, I never knew you could change the wire in the CDI unit. I didn't want to pay $21.00 plus $9.00 shipping for a new one. I searched 3 hardware stores, and 3 auto parts stores for a plug that matched my orignal plug specks. with no go at all. Nothing even came up in a cross reference to that plug. I have searched the internet for a week, but I don't want to pay $9.00 plus s/h for a 2 dollar plug either. Thank you.

Thank You misteright1_99,
None that I have found NGK, Champion, Autolight, Bosch, have a removable cap anymore. All the hardware stores the threaded end of the plug was either to short, or to long. To short, no fire, to long, hits piston. Thank You.
