Having replaced my front sprocket once I seem to remember that it is standard RH thread, righty tighty, lefty loosy (counter clockwise).

Monkey's right.  Its standard RH thread.
Put the bike in gear, put a block of wood across the swingarm to keep the wheel and engine from turning, and heave to with either a long breaker bar or an impact gun.
