Noob question. But I can't for the life of me work out how to set the fuel screw. I know 1 1/2 turns is the starting point but my issue is I'm not sure where 0 turns is? If I turn the adjustable fuel screw either way clockwise or anti-clockwise looking at it from the clutch side of the bike it just keeps turning. I would have thought it would turn and tighten up like a nut and bolt? Please explain??? WR450F 2009 - Australian version.
