As a temp fix I relocated the cables through the face of the points cover so that I could get the machi...

Re: Off-throttle hanging revs

Where are you taking it for the paint?
I need my tank, side panels and mudguards painting in Flamboyant Red.
Would work out cheaper if my painting was bundled with yours.
I live in Dod'oth.

I had checked the pilot jet previously and it seemed to be clear. Not sure where the blockage was but poking around with the guitar string evidently cleared something.

Re: Tyres

Thanks for all the replies.
The rear wheel actually came with a Dunlop K70 fitted. The tyre seems to be barely worn and although it has stood for many years I don't see any evidence of perishing. Seems to make sense to re-fit it onto the new rim.

Re: Zener diode

Assuming that it is the ZD at fault the next question is why did it fail? Do they do this from time to time or is this indicative of another fault in the electrical system?
If it's a common fault then it would make sense to order additional ones as spares.
