Excellent result. What else did you do? I see an uncharacteristic "wobble" as the powervalves open, but I expect that could be down to the MC18 porting.

Here's one of our very first NSR-WORLD "SP" motors (blue trace) compared to an HRC SP kitted MC28. (The MC28 had standard SP barrels.)



As you can see, you could quite possibly be able to clean up the little dip around 7000rpm. We've often found getting them very clean there has even pushed the peak a tiny bit higher, so if you're lucky, you may even crack 66hp*.

*66hp on your particular dyno. Obviously we can't compare specific numbers between different dynos, so our 65.89 could read anything from 60hp to 70hp on your dyno!
