  • Stock 74" Compression Numbers

    Can anybody tell me the average compression number range on a stock 1947 Indian Chief?
    Any help would be appreciated.
    Thank you.

    I don't have compression numbers but I recently ran a leak-down test on my '48 Chief. Each cylinder read 10-11% loss, which to me seemed pretty good, and the loss was through the rings and not the valves. Another related data point is that my bike seems to consume about a quart every 400 mi or so.
