I pulled the engine out the other day. I am very curious as to why it stopped.
First I just removed the head, carby's and exhausts to see if I could see what had happened.
No luck so it was off with the oil supply for the pump, electrical plugs, clutch cable, tacho cable, chain and engine bolts. Then onto the bench.
Still couldn't see anything so off came the cylinders.
Now I was getting somewhere, No 1 piston was not moving freely and its rod would not move. No's 2 & 3 were free. I was running out of time so I'll do the rest tomorrow.
