Dong Fang DF 250 RTB Bobber Information

[axa]

engine blown yet again... this time a cylinder bolt was burned through because I was never able to find the exact cylinder for this engine.
Oddly enough i didn't actually lose that much compression.

Anyway before i have to fab one, anyone ever seen these for sale?

Boy the 167fmm proves to be a nice "reliable" engine until you actually have problems and cant get "reliable" parts in the states...

-failed valve
-failed piston/rings
-failed/incorrect cylinder

I have to nip this crap at the bud... ive found a Yamaha xv250 with less than 3k miles for $400, and have been speaking to a guy in japan who did the swap.
I hope to get that done over the winter... but for now... cylinder stud anyone?
