    2002 Yamaha Waverunner XLT1200

    I have a 2002 Waverunner XLT1200 that does not seem to be firing on two cylinders. It cranks but is really down on horse power...any suggestions.

    Thanks

    Start with a compression check and go from there.

    compression

    I drained all the gas out of it and changed the spark plugs with no change. I did not test with a compression gauge but did take all of the spark plugs out and cranked the engine over with my finger covering each spark plug hole and they all felt the same. I will check with compression gauge....was going to check with timing light and see if each plug was firing. Any other ideas?

    how do the plugs look? are they all the same color? any of them look "clean" or washed? get ahold of a guage and check that compression. you'll get a better idea of where you stand.
