    Re: 750 big pin carbs

    Yea I understand. Itís going on a jetmate so not going to be setting speed records. The motor already has duals on it so maybe Iíll run those. Iíll probably have to re jet for the west coast pipe yea? The engine and pipe came out of a running x2 so maybe it wonít need re jetting.

    Re: 750 big pin carbs

    Factory pipe jetting recommendations have been spot on for me when using an aftermarket pipe of one type or another, so I'd compare them to that. I would in a second ditch a pair of Keihins for a sbn44. I doubt you would notice a loss and tuning is 100 times easier

    Yea. Going single carb sounds better and better the more I think about it.


    Is there a special intake manifold I need for the big pin motor?

    I picked up and sbn46. He gave me another carb which he said was an sbn48. Is that even a thing?

    If it is a 48, it was modified by someone or some company.
    Never argue with an idiot, they will drag you down to their level then beat you with experience.
