Is this dyno normal for a stock bike?

There's something up with that one line. It's all over the place. I found one of my dyno charts from 09 on my bike and just with the cams timed and a pair of Graves slip-ons, I managed 122hp and 66ftlbs of torque but it was a nicely rising chart with no dips or lulls. That was with a stock ECU and no fueling enhancers.

agreed. power curve looks fine, but your torque curve is totally out.

yeah that's exactly what i'm talking about. the torque curve doesn't make any sense right?? to be honest that's how it feels too haha, while riding...

probably need someone with some serious knowledge to weigh in on that torque curve.

out of curiousity, do you have access to any other 848 maps from the same dyno?

yeah Unfortunately I have minimal knowledge the shop that did it said i should get a full exhaust and a custom dyno tune (guess what! they do custom dyno tuning lol so i was naturally skeptical)

But that is indeed how the bike rides. Surges through the lower rpms, its almost unrideable in that area due to the weight transfer lol. if i ever accelerate hard it has to be ~5k rpm + or else it throws my weight forward when the power dips
