904 dynos are getting common around here or what?

After driving 70km in thunder and rain today i finally got to dyno the bike after installing the Wiseco 904.

Max HP: 68,74 Max Torque: 71,95 Nm = 53 ft/lbs
The setup for the bike now is:
Pipes, modified stock
Carbs, stock 145 /42, TBS Needles
AirBox bottom cut, no snorkels int/ext, K&N air filter
Bike is running rich in the midrange and that seams to be a common problem around here

I had a good talk with the dynoguy and have some ideas for improvment but i really want your suggestions so fire away!
