    How fast is the 79 550L

    Just looking to see where every one else is at...

    what is the maximum speed of your 70's era 550

    Also how much of a performance gain will you typically see from an ignition upgrade (points to electronic ign.)

    I've had mine up to 90 and then I got a bit scared. I'm a rookie, also bike was in need of a tune up bad. Its at the shop now.

    Hope to find out it goes faster when I get it back.

      Mine was fast enough for the Maricopa County Police to set up a road block for me back in the 80's 8O There was 4 ahead of me and 1 way, way, way behind me. It's amazing what a 14T and 4-1 exhaust will do :twisted:

        I pulled an indicated 107 mph at 9000 rpm and it could still pull to redline, so maybe 112. This is a 1980 550E.
