I spent quite a bit of time....and cash getting mine to run right, although it has to be said even as it was when I got it it wasn't terrible or unride-able or that.
At present mines sits like this:
1. Power commander V
2. 14t sprocket......soon to be +3 at the back
3. Servo valve delete
4. MWR Race air filters plus power up filters
5. Stock exhausts and catalytic converter delete
6. Dyno'd and dyno setup for more power and correct A/F ratios
It runs well, I can let drop to 10/15mph in third without any hunting issues if I want. I dont really do that tho, going through a village at 30 mph in second doesn't need the clutch slipped or anything. In fact I hardly notice it anymore and i'd probably get a shock if I went back to stock bike.
Only down side for me is that a fair bit of the engine braking has been dialed out. which I do actually miss if i'm scratching, I now need to apply the brakes occassionally
