like probably many others over time, when my GRiSO started to present issues, I was sure it wasn't the classic, easily remedied 'startus interuptus'. I fiddled about for sometime at significant expense and frustrations, then ponied up the dosh for the kit. Once installed, I've had no issues at all for thousands of often very wet and very isolated miles/start ups.
Buy the MPH kit and get on with riding.
