I'm having the same problem as you John, only the left grip getting warm on mine.
I imagine it would be difficult to make a coonection to the the twist grip unless it heats the stationary part.
Can't find any loose connections.
Well, my heated grips work fine. It's a shame there's not more range of heat adjustment though, like you get on after market ones. Mine has three heat settings, off, hot, and burn!! But to be fair though, the weather has not got very cold yet.
Hehehe, thanks for posting that PAKA... I've had my Tiger 10 days now (loving it!), and I was gonna bring the no illumination thing up at it's next service.
I know it's perverse, but I'm looking forward to a really cold day here in the UK (middle of October in the UK and not cold yet? Very odd!) so I can test 'em out properly...
