Walking backwards

One step forward, twelve back...!! So I need to find the advance timing position to set the magneto up, so first I need to find TDC, no problem, couldnt find my last piston stop so I knocked up another one quick sticks and put it in the engine. Then instead of tunrning the engine nice and slowly I used the kick lever and bang! The bloody bit of metal I welded on the end of th spark plug falls off into the cylinder.

Tried for AAAAAges to get it out to no avail, so it was a case of totally stripping the bike to take the top off the engine....



So now the bike looks like this;



Waiting for a new gasket set to arrive to I can put it all back together... fml.
