A1R sold on eBay
Price was reasonable
There should be some stickers on the tank.
That is the original 4LS front brake

In this case the kickstarter shaft was retained: Maybe an indication of a roadbike based racer? Usually you'll find the oil sight in its place. Note also the selector arm sticking out below, indicating a correct part. The A1/A7R gearbox arm was longer to allow for Brit/colonially inclined riders to have RH selection.
Correct exhaust mounts, means the cylinders are race type (spigots).
Correct Tach. The last one I saw (sold by mistake, the guy didn't know what he had) fetched almost 600$
