    New to the forums and to the Triumph Universe.

    I recently purchased a used 2007 Triumph Bonneville with just over 15K miles. After purchasing the bike, I began to experience issues with intermittent failure to start up. After diagnosing the bike not getting spark, I replaced the coil with a Nology, then ended up also replacing the Ignition Switch with a ProCom CDI unit. Now, the bike starts up just fine - getting great spark! However, I'm now experiencing intermittent issues with the bike stalling when put into gear. And also sometimes dying while in gear at riding speed.

    Now, before everyone comments about the problem being the kickstand switch -- I thought that was the problem too, so I just bypassed that by jumping the wires. I know the wire jump was successful because I can put the bike in gear with the stand down and it does not stall. This intermittent problem does not seem to be related to the kickstand.

    Any ideas on what the problem could be?

    The first two things to check are:

    the neutral light switch (part of the ignition lock out circuit) and its terminals that screws into the floor of the gearbox

    And

    The pick up coil. This is your ignition trigger under the triangular RH side cover and probably the single most unreliable element of the entire ignition system.

    Sticky switch on the side stand?

    I would have said clutch adjustment for the first bit but actually Cal probably nailed it with pick up. Must be mid winter.
