The bike had a modded intake, no cat, twin arrows with no baffles and a little tune work.
After I put the Daytona cams in it was over 111 to the wheel
The only thing I can figure about the afr at the beginning is due to the way he ran it up to fourth to about 8k and then let the off and let the engine "brake" with no throttle. Depending on when they turned on the logging in relation to getting on the throttle again is probably the difference...I don't know, but that's the only thing I can figure. At the end it's, of course, running in to the rev. limiter which apparently cuts fuel explaining the extreme lean condition I suppose.
Modifications so far:
Axxiom valve kit, Traxxion spring kit
CBR600RR shock, Tail Tidy, Triumph bar end mirrors
FP Racing levers, -1 front sprocket, Gel seat insert.
