  • Connecting the Compression Gauge

    Hey, all! Quick question and I promise that I read the directions - I have a "Y" chromosome after all- and just want to make sure that there isn't a difference in checking a motorcycle compression vs a cars. The directions said to disconnect the automobile's coils prior to checking the compression.

    Would I need to disconnect the coils on the motorcycle prior to running a compression check? Can someone explain how to do that if it is required? If there are other differences, can someone post them so that other newbies can figure it out?

    Did I post about how the local motorcycle guys managed to extract my pilot jets for a six pack of Dos Equis? $7.99. . .what a deal. Reminded me of the "old times" when to get my bike wrenched all I had to do was say, "can I bring you a beer, honey?"

    Thanks, all and hope everyone is well.

    The idea of disconnecting the coil is so the engine does not start while you are doing the compression test. On your XS, just remove the sparkplug wires, take out all the sparkplugs. Then do the compression test one cylinder at a time. Remember to hold the throttle wide open while you do the test or you will get artificially low readings.

      Warm up the bike, then kill it. Pull all the wires off the plugs and take all the spark plugs out... carefull, they'll be hot. Screw in the compression tool into one of the spark plug holes. Hold your throttle wide open and hit the starter for @ 5 seconds. Get your reading.. then move to the next one and do the same thing.
