Mr.R wroteHi Mick,
As Griff's said it sounds like a low battery output to me, or a poor earth connection.
Jacknipper,
The neutral switch has absolutley no bearing on how the bike/bikes electrics perform, other than to tell lies!
I always remove the neutral light switch and blank the hole off with a bolt.
That way it can't tell anymore lies!
Over here in the UK older bikers call these "Idiot Lights"...
They weren't fitted to bikes years ago and we don't need them now.

sorry my mistake ... I confused it with the side stand switch that caused 30 mins of panic with my 998 the evening before I've to go to Rjieka track 😱
