Hi Rocketned,
Welcome....are you a High Beach regular?
Had a similar problem with my 2007 Classic, took it to North City in Chigwell, replaced a sensor and all is well, a very switched on workshop team who are very helpful.
I have a bypass pipe fitted, not bothered about loosing the noise or a bit of power and the popping on decel is driving me feckin mad!!!...will it run better? will it need re-mapping? opinions please.............
On my 07 UK model the clutch must be pulled in for the starter button to work (have been caught out once or twice!!), it will start with the sidestand down but will cut out on engaging first gear if still down............
With ignition on press grey and black button together till it beeps, switch ignition off (now in sleep mode)..... after a minute switch back on and alarm should sound press grey and alarm now switched off and re booted....good luck!
Always use grey button only to switch on and off.....
