BSA A10 RGS style

Built from a rough frame found at a swap meet. The wheels were intended for a race bike but ended up here. New pipes from UK , Tank from Wales, mufflers from Emgo ,locally done seat based on HD Sportster and the Rocket Gold Star engine cases picked up in a bulk deal I swapped 2 bikes for. I see it has some valve guide smoke which clears as the throttle is opened. Oil will pull down where it can on over run or idle whilst the slide is shut then clear as the throttle is opened up. It may need guides. Bore is fresh with 3 piece oil rings. Bit disappointed but not a big job to pull head and check. The head is a bit dodgy anyway and has been got in the inlet tracks. An expert I guess. EX being an unknown quantity and spert , a drip under pressure.
