    Am6 Main/ gearbox bearings?

    Hi all, just wondered if anyone can tell me the exact sizes of the main bearings, gearbox bearings and balance shaft bearings for the AM6 Engine's?
    Also if possible the sprocket and gear selector shaft and crank seal sizes?

    I doubt they're the same as my RV6 as that has 3 main bearings.

    Thanks,
    Connor.

    Even if it doesnt show the size, they show an alternative part with sizes in the part details if available.

    Is there anywhere to purchase a crankcase gasket or do i need to use sealant/instant gasket or something similar?

    My Minarelli RV 6 had a crancase gasket but i can't seem to find one for the Minarelli AM6. Have all the other gaskets but not that one.

    Thanks.

    Between the two engine halves you use instant gasket

    Just make sure that it's oil/fuel proof!

    Thought that may be what you have to do considering there wasn't a gasket when i split the engine.

    Thanks
