thats an interesting one, id like to see the clutch , rod and the mag to be sure.

Looks like its been apart so im worried what left inside, Elects are not YZ wires, cover is wrong, so hard to say after bush mechanics whats YZ left inside either and head oxdised so where has it been sitting.

HEad bolts arent in properly so its been appart, be better if he had a shot of the barrel off so we can see inside. 
I'M wondering as are a few other, if its not the old DT1 internal with yz case covers, out of all the photos no shot shows the head with those other 4 x10mm nuts as a YZ should as well as the 4 big drop bolts.

Why has a Dt1 piston port carby been fitted ? where have they drilled the mounting bolts into ? the reed cage ? or has that been removed all together ? 

Posses kinda more questions than answers, pity he wont give out more info , i have sent a few emails already for more info and photos, but nothing as yet.

ITs getting up there for the dollars without the other info id say $200 on the cases if you have the frame, and $200 on the clutch cover, everything else needs to be confirmed cause a lot dont look right there, but lets wait and see what he says  :-\

it looks like a point IGn, not YZ thats for sure, head is correct from new pic's but that bolted up DT1 piston port carby screams HTF did they get bolts tapped in there. 

It has some useful bits, its just a be warned i think, just incase, imings think its at about fair value right now. 

OTher have said way over as Gearbox will almost certainly need a rebuild, but i dont know enough about that .  BAsil ?
