    85 350x Stalls when Hot

    after 1 hour of riding today the engine stalled out when I slowed down and let off the throttle. Afterwards it was harder to start. Usually the bike starts first kick when cold. Any ideas?

    Hello


    More info is needed

    Put plug on head and check spark, is it weak yellow or strong pale blue?

    Does compression still as strong?

    If gas cap has a vent knob on it loosen cap to let air in then try again.

    Drain float bowl gas via drain screw into narrow glass, look for sediment, water bubble at bottom of glass [water sinks in gas], color of gas [orange is bad.

    What color is plug lite tan is good, dark tan slightly rich but ok, dry black is way too rich, moist gooey black is burning oil.

    One more suggestion for the list..running too rich!

    Does it start better if you crack the throttle open and bit when it's hot?
