Emissions....
MOT Time again,
Cat fitted, mixture adjusted on the power commader and got the following results:
CO 0.01 - 0.05
HC 30-50
Lambda 1.07
I tried richening it up even 1 point on the power commander and the CO would go upto 0.8 ish and the HC upto 250-300.
2006 R1 with power commander, MNR exhaust, Piper cross air box with K&N enclosed cone.
Anyone any ideas? I thought lean to start with but the low HC suggests it isnt?
Thanks

Question is what RPM are you required to hold it at? Is the catalyst hot?
I'll be MoT'ing my R1 (2005 5VY) transplanted car soon, so I've got an interest here. The previous car (2002) I've MoT'd
has had GSXR750, 1000 and 1300 in it. The MoT 'performance' was a merry one, I had a Volvo 90 catalyst can welded to a Jetex catalyst can.
The MoT tester allowed a certain margin on revs, while I played with the fuel pressure regulator (drastic reduction) and PC fuelling. Engine just
about ran.
The 1000, in particular, had zones where emissions clearly were secondary to the noise issue. Very difficult to get it right for a given rev, better
to adjust the rev to get the emmission in the right ballpark.
My R1 transplanted thing has a 'Q' plate, so I'm hoping it'll be less demanding on emmissions (some say 'Q' is
helpful), however it probably won't be.
