Re: Dong Fang DF 250 RTB Bobber Information
I've used my compression tester like this one below many times over the years. Should be done before tearing into an engine.

Maybe one can be borrowed from a auto parts store.
Really doubt this problem is caused by the leaking exhaust gasket.
The cause of the "loud dathunk " needs to be found.
Re: Dong Fang DF 250 RTB Bobber Information
I wonder if a valve adjuster backed off enough to not open the valve properly.
Re: Dong Fang DF 250 RTB Bobber Information
I am pretty sure the adjusters are tight. but once I get her back together I will triple check the gap.

If I could reach into this forum and give every one of you a firm hand shake I would. I want to thank each of you for the awesome assistance for helping me get my baby back on the road. Head gasket it was.. so it seems. It came in yesterday, I put her all back together today, and took her for a nice ride. She is practicaly new feeling. You are all the best. I have learned much from each of you, and hope we can all continue to support each other through our coming rides. Peace and respect and a hearty thanks.

im real glad for u. and just think, you guys were this close to picking out a new engine.
did you torque to about 21 ft/lbs i think i read.
i bet it was your just your head bolts that got themselves loose over all those miles you rode.
Re: Dong Fang DF 250 RTB Bobber Information
bow,
Great news. May she run another 18k miles.

i found similar sets last nite, and i turned a new set this morning before work...
to a not for profit machinist like me, 24$ for a set of bolts seemed really outrageous
but then there are these, 2 sets for 9$, though you'll probably end up with the same problem later.
