I would say:
- don't be too cautious with the clutch during the running in period, babying it doesn't do it any good. Get 4000 rpm on and then take it from there.
- The clutch fully engages around 4000 rpm normally but if welly the throttle wide open it can slip for longer than you would want. My experience backs up what I have heard others say, allow the clutch to lock up before booting it in order to get the best performance and clutch longevity. It is only varying the speed the throttle is rolled at, not a big noticeable pause.
- I find the best riding position is to have my feet right out in front of me rather than on the floor in a "sitting at a desk" position. It took a few rides to get used to it and it also has the advantage that you can lock yourself between the seat back and foot rests if things start to go bad. But on a long ride I use all the various foot positions to help with numb- bums and back fatigue
On my first "spirited" ride with the 400 I kept wondering why the hell the bike in front of me kept pulling away from me and then lifting off for no reason, it took me a while to remember he was having to change gear
