    Are there any jetting differences between each cylinder? If not, then it probably doesn't matter. The different length snorkels mean each cylinder has peak torque and peak power and differen locations, it helps to create a broader power band

    Short one goes on rear carb facing forward. Long one on front carb facing backwards. I think.

    Its all back together again and running.
    It took me forever just to work out the correct routing for the throttle cables, choke cable, breather and drain tubes.
    One of the carbs has a needle and seat issue and pisses out fuel all over the place.
    Still need to bleed the brakes also.
    Then off for a roadworthy and club rego.

    WoW! Looks great, congratulations. One trick I learnt was if the carbs are at all suspect, I place them in a plastic tub overnight with a gravity fuel feed with a piece of a4 paper under the carbs. If there are no stains on the paper the next morning it’s safe to assume the needle and seat and gaskets aren’t leaking,,, such a pain re fitting those carbs, I prefer to only do the job once if possible.

    Thanks Gizzi. Yes, the carbs are a pain to get at. Even fitting the engine to the frame is a bit of a squeeze. I found the best technique was to lift the engine and get the front mount bolts installed first then swing the rear up into place.
    The carbs are leaking so much fuel. One of the needle is not shutting off fuel at all. It is fairly obvious.
