    How does one tell if clutch switch is faulty? Does it cause bike to stall while riding down the road? Has anyone ever by passed the clutch switch? Is a faulty clutch switch a known problem on the twin F650's?

    Thanks in advance.

    Many modern bikes (especially those sold in the USA, I'll leave it to you to figure out why) have switches on the clutch lever and sidestand, which together with the neutral light switch are intended to prevent the bike:

    • starting when in gear with the clutch engaged
    • running when in gear with the clutch engaged and the sidestand down.
    A faulty clutch switch alone will not stall the bike while you're riding, since its turning on and off whenever you're using the clutch! A faulty sidestand switch may stall the bike; if the bike runs in neutral or with the clutch pulled in but stalls when you release the clutch lever then check the sidestand is up and the sidestand switch is working correctly.

    The great state of confusion
    If it helps:
    The side-stand switch has 3 wires: red / white / brown (usually brown)
    The bike thinks the side stand is UP when the red-white are connected.

    The clutch switch is faulty if you pull the clutch lever in, hear the click, but the bike still won't start in gear. I replaced mine recently because of these symptoms and the bike now starts in gear with the clutch pulled in as it should. I am thinking of butchering the old switch and making it into a permanent short circuit which can be plugged into the clutch switch cable should this happen again. On the other hand, it took 4.5 years for the first switch to fail.

    My 800 would not run in gear regardless of clutch position if the sidestand was down... that is before I broke and hot wired my side stand switch.
