Not really Dave as I haven't had the time to experiment with the couplers etc.
Have you tried disconnecting the coupler or any of my hair-brained schemes on your NC ?
As an aside, Lings in Harleston lent me an NC something (can't remember the exact model) a couple of years ago.
750cc Honda auto with a Sport/Normal switch, think it had a cubby hole for a crash helmet.
I absolutely loved in sport mode ... to me it went like the clappers ... perhaps that was because I rode it as I used to ride my previous motorbikes or as I call modern bikes "Licence Losers"as they demand to be ridden fastish.
Does this sound like your NC and how do you rate it ?
I ride my Forza 125 with let's say spirit ! The engine seems to love it and I think it handles well in the twisties, in fact I make almost the same time on the A143 back road from Bury St Edmunds to Cambridge as I did on my Tmax.
