Geoff could you knock down pipes for the A model for dirt track use or could these fit 
Been meaning to drag out the Suzi notes to check the spigot size but keep getting sidetracked, my gut feeling is the engine spigot was different from the M/S models to the A model.
Essentially I think the pipe specs will work good on the A model
Fitment wise it may need a different spigot fitted.
Also the bracket would need fiddling with as the A model wouldn’t have the mount for the muffler on the frame.
