Default Problem with diagnostic mode, need help!

Hi everyone,
I am driving Fazer 1000 naked, 2007 and I need some help. I have noticed that the fule consuption is vary high. So I asked arround and it turned out that the previous owner tampered with values in diagnostic mode. Since I am new to this I don't even know what these values are. I will put the values here and ask anyone who konws something about that, and what the values should be.
When I eneter diag mode I can choose between two values, d01 and Co.
Here are the values for d01
01 15
02 100
03 100
05 42
06 83
07 0
08 0.6
09 12.4
20 off
21 off
30 00
31 00
32 00
33 00
36 00
37 00
38 00
39 00
48 00
50 00
51 00
52 00
53 0
56 0
60 00
61 30
62 1
63 00
70 0

and the values for Co

C:01 7
C:02 11
C:03 11
C:04 7

Please help me with this. Tell me what these values are and what should be the basic values as in factory settings.

THanks

The only values I see that indicate something unusual are the 61/30 and the 62/1. I find the manual difficult to follow but I think the 62/1 means there's one (1) history of a fault code and it looks like the 61/30 means the lean angle sensor went off. I don't think values can be changed in diagnostic mode..only the condition of the fuel/ignition/sensor system monitored.
The 01 is throttle position sensor and should read 15-18 with throttle closed...you're at 15.
02 & 03 are atmospheric and intake pressure readings.
05 is intake air temp, 06 is coolant temp.
07 is speed sensor, 08 is lean angle sensor and "upright" readings are 0.4-1.4
09 is battery voltage...12.4 is good.
The rest are various safety switches like "side stand" and "in neutral".

I have no idea what the C:01, 02, 03, 04 readings are but am guessing it's something about "cylinder 01,02,03,04"... maybe injector pulse settings of some sort?

Found this with a Google search (FZ1 CO diagnostic)... http://www.g-mac.net/fjr1300/gen_2_fjr1300_bjm.pdf
It's from a Yamaha FJR forum but enlightens as to what the CO readings are about. Basically, the higher the number the richer the cylinder is set to run. Looks like a very involved process changing the CO settings but it would be interesting to compare other FZ settings as the FJR and R1 groups mention a variety of configurations.

Very interesting that it also works on the FZ1,
My reading for each cylinder is,
C:1 -5
C:2 20
C:3 20
C:4 2

What are others set to across the world? lets compare.
It would also be interesting to know if the C: 01, C: 02 are firing orders or from left to right cylinders.

I'd have to check mine but I can tell you they've never been changed.

I'll be sure to post my findings next time I lift the tank. I wonder if using a Power Commander throws these settings out the window...or do the CO settings also alter the PCIII percentages?
