Reluctantly took my bike to get a dyno done this weekend to see how many horses I had lost, but to my surprise I hadn't, I say this because as far as I'm aware my bikes to a degree stock, bar a scorpion slip on can and a ignitech, my results are as follows from the rear wheel

64.1bhp
28.5ft-lb of torque

Mean fueling was around 13.3

Am I right in saying a stock from the factory nc30 is 59bhp at the crank?

yes that sounds really good.
some dyno operators use "correction" to make the figures seem better sometimes but that sounds good anyway

Dynojet dyno?

good numbers though but dynos are best use to see a change in the bikes performance against any changes you have made. I tend to be more interested in the smoothness of the graph than the actually output.

I have had any where between 68 and 58 from mine but all on differing dynos's.

Yeah it was a dyno jet dyno
