I agree with the you.

That richness in the mid to upper rev range is killing you.

The cam seems to lose torque early on in the rev range, shouldn't it stay on longer?

You need to find a dyno tuner that knows what he's doing. You are running super rich and will probably be fouling out plugs like crazy.

You want your AFR to be around 13.2-13.5, almost like a straight line right across.

Yup! I may not know what I'm doing, but I know I wouldn't pay for that tune!

 

I would find another place to go to.

WOW he let you leave with the AFR looking like that!!!

Where the AFR line for the run on 4/24/04 and why is that run on there? Is that yours also?

 

I agree with all of you. The tech said that if he changed the jet again that the bike would be running really lean. Yes the 03 run is from my bike. They were having an open house and were doing free dyno runs. No tunning, no afr's, just runs. Here are my runs from 03 and 04. Again no tunning.

carb or EFi , no bike would leave our shop with an AFR line like that! You can no doubt have abetter AFR and find a gain in HP/TQ with some additional tuning.

Not trying to bash you or anything but if you look at you first run the blue line it was making more HP before you put the cams in at about 4100 RPM. JMO but you need to take it back to the dealer that did the dyno and tell them to get it right, Or find somebody else you are leaving a lot on the table there.
