    Re: 89 650 possible misfire ?

    So I re-read your first post and its probably not a sheared key, but I do think its ignition related. Running on one cylinder with a single carb is probably not the carb. I would test all the electronics you can and go from there. Could also be the flywheel magnets getting weak causing a weak spark.

    I tested the coil assembly on my bench just now (out of the ski). There are 12 resistance checks on the Kawi chart from the service manual. I drew up a hand-written chart with the test values from my coil assembly. Here are the correct Kawi values and here are my values (both attached).

    85 550 (Power by PoM)
    86 550
    Southern fleet:
    89 550 (half owner, nice loaner ski)
    89 650
    92 550
    82 550 & 91 650 (don't own either, but do all the wrenching)

    (prop, plate, grate, bars on everything...and other assorted mods on the whole shootin' match)
