I know the OEM parts are pricey, but I think they save headaches in the long run. I would test the starter button, relay, solenoid, and starter as described in the manual before throwing money at it. A cheap mutimeter works fine for resistance checking, and is really a must if your going to diag your own bike. These procedures are also described in this forum and you just need to use the search feature to find. I see a slightly more expensive Japanese relay in your future.
