I have a 2008 zx10r. It will not start and it won't stay running unless i lean it over or sitting on kickstand. As soon as I stand it upright it shuts off. It will not start again until It is leaned over. I'm a newbie and have no idea what to do
Possibly the tip over sensor? Not a clue where it is or what it looks like on your Gen 3 though. Maybe someone else can chime in. Has the bike been crashed before? And what exactly is leaned over, laying on its side or just the angle from resting on the sidestand?
Defiantly sounds like the top over sensor got moved slightly and only makes contact when tipped instead og when upright. Basically working exactly the opposite of how it should. The gen 5 sensor is under the rear seat. I have no clue about a gen 3 though.
