Impressive project! Crazy to see the bike torn down like this.
What was the reason for the seizure? I vaguely recall the for sale thread.
What is your general impression of the condition of the mechanics of the bike given the mileage and use?
I bought the bike with the knowledge that it had heat-seized - apparently due to a water-pump failure.
When i stripped the barrel & piston out, it had not seized, in fact it was in very reasonable condition - so much so that after a bath in parrafin, i sent it off to be hermatically measured

- in a temperature & humidity controlled measuring room, the barrel & piston both came back well within original spec. I did not replace either, but I have put new rings in, purely as a precaution and as the motor was open. I was extremely happy with the mechanical component condition and I am happy with the bits I have done.
The rest of the motor, gearbox etc., is in pretty fine condition. I measured runout and thrust washer thickness tolerance - all within spec, same with the selector fingers and all the gears. I replaced the waterpump, complete with the seals and drive gears (you have to split the motor for this)
The output shaft splines are worn, but thats not in the budget (sadly) at the moment. I have however replaced the white metal bearing on the crank (R2500 per set of 4 halves) and all the roller bearings in the motor (R500 from BMG) as well as the wheel bearings, chain rollers, and steering head bearings.
Also replaced all the bushes in the suspension, along with the seals.
There is a fair amount of general wear on the bike (plastics have had a hard time) and the chain has eaten a small section of the underside of the swingarm where it wore through the slider strip - and into the bearing cage..... This will be dressed, but thats all.
These are apparently pretty strong bikes - although I have not got to a point anywhere near starting it - I did manage to start motor assembly this weekend, but I forgot to do valve stem seals (I have them already, just forgot to do the job), so that will wait till Saturday morning when I can get to Halfdaft.
In the emantime I also have a XT500 that is nearing completion.....
