still trying to find pics of the action, and havent had a chance to touch motor as have a several thousand km ride on my ZB33 coming up very soon and top ends still off.
Will try and get a better copy of this photo.
technically we had two pre 63 outfits entered, mine and an 800cc matchless that is a full replica, no original parts. There is also a 820cc 6 T based machine with disc brakes running in pre 76. all the rest were small wheelers with more modern engines.
Am fairly torn between rebuilding as a good honest a10 or sinking money into trying to keep up as a bored and stroked special. Problem is the A10 is the oldest bike out there but is very popular and on tighter circuits still competitive as a 650. something to ponder.
