Am going to go with triple 1 /4" SU's on my grey motor, I've got a manifold and am looking for some 1 1/4" SU carbs. Anyone got any at all they want to part with? even if I get them one at a time as long as I can make up a set.

When you find some try and collect them so they have the float bowls on the left hand side when looking from the air cleaner (floats to the front), gives more room with the back carb, and minimises fuel surge. That way the fuel flows towards the main jet when accelerating
Happy hunting Mick
