Dong Fang DF 250 RTB Bobber Information

[axa]

I just mounted one of the cylinder heads I have acquired, I found the mounting head cylinder bolt holes up to ¼ inch out of place... but I relocated the holes...
thing is I apparently didn't do it exact so when mounting needed to leave out the cylinder to head mounting bushings to get it to fit.
These are 3 metal inserts that slip over 3 of the head bolts and fit precisely on to each half of the cylinder and head making sure it's in the correct position and centered...

point is it should be know that if you blow up your engine you won't be able to find proper replacement parts for this loncin version of the 167fmm...
and unless you ate a machinist, you might well be shit out of luck.

trouble is that all these parts are all made differently and every one who sells them has no idea what they are selling,..
and in the end I could not find drop in replacement parts, so I recken you just might be better off replacing the entire engine

if I did it again I would never buy this bike or any with a clone Chinese engine.
it's a crap shoot....
