The F4 vs F4i dynos:

The F4i are more consistant in their hp ( go figure with the fuel injection ), but only seem to be a few hp more than the F4 (and only because I've seen some poor F4 dynos...).

I've seen a F4 dyno at 101 hp (hindle pipe), simular torque numbers as mentioned.

As said - as long as you're having fun on the bike the dyno means nothing although certainly handy for tuning.
