    What kind of exhaust blocking plates do people need?
    Ive gone ahead with the intake boot plugs.  Ill measure all the exhaust stud patterns on motors i have, but i dont have everything.  Try to make them work for multiple engines.  Dimensions from interested parties would help.

    Heres a few pictures. Picked up the first of the carb boot test plugs.  They fit mikuni carb boots for 36-38 and 40-44 series carbs.  These will be tapped and fitted with air fittings on both ends.  Another run of plugs will not have a hole through them so you can block half of a twin if you like while testing the other half.

    Here is a design for the exhaust blocking plate for pressure testing.  It has slotted mount holes with 70-80mm hole centers for 8mm bolts. Will come with a pressure gasket. Since no one responded. I wont be doing any other variations for different exhaust stud patterns.

    The test plugs are finished. Here's a couple. The solid version as well.  A twin kit will have one solid plug and one pressure fitting plug.  Working on exhaust blocking plates next.

    O-rings?   No they are grooves. They seat on the  rasied lip inside the mikuni carb boot.

    Sorry for not keeping up.  Forgot to hit notify. Are you past exhaust measurements?  I will still take a complete kit.

    Yes no one replied so im only doing a standard 2 bolt exhaust plate with hole centers slotted from 70-80mm c-c that should cover most appls. If it doesnt and people have 4 bolt exhaust or others they are sol.

    Here are the finished leak pressure test parts.   A delrin(fancy plastic) mikuni carb boot plug. Either tapped for 1/4 npt or solid.  The exhaust block off plates and an exhaust block off gasket.  The delrin plugs fit 38mm style and 40-44mm style mikuni carb boots.   The threaded plug you hook up a low pressure regulator or hand pump to pressurize the engine to 5-10 lbs. Any higher is not recommended and may blow out your seals.  The kit is sold in single, twin, or triple configurations with your choice of solid or tapped plugs.
