Start - fails first, starts second

Hi guys

Hope everyone in the UK is enjoying the cold weather and salty roads.

I'm experiencing an intermittent issue with the SD starter - on some starts (mostly cold I think - need to do more testing though), the first time I press the starter button all I get is a click and the engine doesn't turn. On the second press, it all starts fine.

Anyone got any ideas?

Muchas gracias!

Check all connections would be the first thing I would do. While you have the battery box open check volts across the terminals with bike off, them ignition on, turning over, tickover and finally holding 6k. This will eliminate RecReg and battery off the list.
