    I have the original 80 bores sitting in various sheds (4) since I swapped then out in 1984 they still look OK no rust or pitting just a wrapped in a sometimes oily rag.
    Bike sat for a few years while I went sailing.
    No ill effect on the bores but final drive & gearbox not so lucky so not perfect storage conditions but inside and level

    Thanks for the great explanation of the Spigot Disston.

    Oh yeah - Most of my 1500 posts are questions, I just hadn't got around to asking that one yet:lol3

    The oil turns acidic sitting around. Eats the iron and steel. My bike apparently sat tilted to the right (which is odd) and a puddle of oil sat in the cylinder, above the piston. Ate away the iron and did not affect the aluminum. Fortunately, it also stayed off the valve seats.
