Starter circuit fails to work, or only works with in neutral with clutch out.
Engine runs in neutral, but dies when I put it in gear.
There are two known causes for this. First, the side stand switch can corrode and sieze up or get bad contacts. It is best to bypass this switch before it goes bad and leaves you stranded in the wild. To do so, simply disconnect the connector at the switch (under the small, black plastic cover), and short the harness wires together (brown and green/white) with a jumper. The second part is the clutch safety switch at the clutch lever, which tends to fall out of adjustment. To bypass, disconnect the plug from the clutch switch underneath the cover on the instrument panel. Short the black/yellow and blue/red wires on the main harness with a jumper. In both cases, the switches can be reactivated by removing the jumpers and plugging the connectors back in.
It is also possible to bypass both at once by bypassing the starter safety relay: This is not the main starter relay, but an adjacent, secondary relay that is used to manage the safety circuits. Remove the relay, and connect either of the yellow/red wires to the black wire, or use the yellow/red wire from the small relay to replace the black wire on the starter relay. The starter safety relay has the same part number as the fan relay, so hang on to it; they're not cheap. There are reports that one of the safety circuit diodes still needs to be grounded for the neutral light to work properly; you can do this by bypassing the sidestand switch.
It also appears that the "running safety" circuits can be bypassed by grounding the red/black wire coming from the CDI unit, but this has not been confirmed.
