Well I took it out for a blast and some motorway to see how it handled it and to let Megasquirts Autotune at it.
70 on the motorway isn't a problem really other than the noise. Doesn't feel twitchy or anything.
When you get off the motorway though it seems that this thing comes alive after 4000rpm. I'm going to have to get used to changing gear a lot later to get the best out of it. Its a bit like riding a redistricted two stroke motorbike.
