engine comes out the frame for the second time
sprocket nut had been fitted with out lock washer, wouldn't undo with airgun, so had to be split with drill and chissel.
clean 3mb head was a bonus!
.5 oversize piston, which turned out to be undersize for the bore, explains the piston slap when cold

might also explain the markings in the bore
rest of the engine came apart pretty easy
I've had the crank rebuilt and barrel rebored, and have bought all new bearings for the engine. Just in need of a intact power valve cap and temperture sender (engine has the warning light type fitted). Then can start building the engine up, when I get some spare time. Also looking at fitting road tyres to the standard dtr wheels, if anyone has any recomendations on size and make? Cheers John.

Yeah unfortunately that nut is connected to the output shaft
I wouldn't want to be hitting that with a hammer and chisel personally!!
Especially as that thing is going to be rotating at some silly speeds during operation.

With the nut drilled out, your only chiseling through about 1mm metal, with a nice sharp chisel it takes surprising little effort to split. Your tapping it rather than clouting it with a hammer.

Oh good. I thought you were chisling it all the way through lmao. That would not have been good lol.
