Brockett,
It is the fact that more power is available I find interesting.Like the 650/1000/1050 it points to the 800 being understressed as std,which should be good for long term reliability.
It also means a tuner has some wiggle room to play about without LOOSING power on a std bike.
A good dyno operator/tuner can do what the rider wants,be it more bhp or more mpg .Or filling in holes in the torque curve making it more rideable.Even on an otherwise std bike there are usually gains to be had in throttle control and rideability.
Track Electronics ( my local bloke ,and a bloody clever one, Hello John ) charge £350 for a custom reflash with as many dyno runs as needed .Not too bad if it gets rid of the vibes (time will tell, but the vibes coming in at the same time as the torque starts to build may point to an answer)
Of course the manufacturers warranty is void if reflashed, so it may be a while before we see many 800s reflashed.
One of the reasons for me not wanting an 800 was lack of back up in the accessory / suspension market yet.
But it is a good bike so I am sure that will come in time.
