Have to say I like to see the results, if for no other reason than to see how bad I really am against the others. Kinda lucky though cause both the clubs I'm in have the results up quick.
Start unbolting the tank/Mud guard etc, it should all pull apart easily enough I'd have thought. Clean fuel tank out, new fuel, clean carb, new plug etc.....it's how I would start anyway
Hope it goes well for ye, looks a nice oldie
