Alan,
Would you be inerested in a whole motor cycle.
I know of one that has been off the road for a number of years.
I have been trying to see the owner for over a month.
I do know that the ignition requires re - timing which was due to happen in recent months.
That's about all I know about tyhe bike, I was due to have a look but have not seen the owner.
I will keep looking for you and let you know if I find any thing.
