Dong Fang DF 250 RTB Bobber Information

[axa]

I've enjoyed my Bobber for the past 2 years and was out with a friend enjoying the Natchez Trace when I heard a mechanical clank and my engine shut down. After a 3 hour wait on the road for my friend to get her truck to bring me home, I pulled the spark plug. To my suprise the sparkplug tip is damaged. I haven't pulled the cylinder head yet, but I'd like to know if anybody has found a parts supplier for the engine before I try to tear it down.

Per requests, here are photos of the spark plug. It's an NGK plug I had replaced for the original plug.

catastrophic physical damage.
im going to guess you did not have too many miles on the plug, so it was something else.
Your going to have to take the cylinder off and inspect the extent of the damage,
then acquire replacement parts.

That or... just buy my engine
