Re: Oil Leaks - Singles

This is how I sealed the oil leak from my magneto some years ago, it is still working ok, I am sure that it is one of many methods.
The alignment/clamping tool mentioned in the text is shown in the picture attachment, it has been posted before.

Hope this helps.

Re: KICK START JAMMING

There is only one penny washer, my sketch is incorrect, the arrow points to the spring retainer and not the penny washer, sorry for tha...

Re: Angle BTDC - ignition setting

I suppose a way out of our dilemma is to ask John.bebb if he would kindly take back ownership of our bike ;).
