I am under the understanding that the most accurate way to test is to drill the headers on the vertical part to accomodate sensors as the balance pipe makes it difficult to differentiate between left and right cylinders.

I am not brave enough to do this so my mate who owns a dyno adjusted the settings by ear and the dyno now shows 1bhp improvement but, more importantly, the revs top out 1 second quicker in top gear. No more stuttering on pullaway too .

This is with the air box mod and the CO settings were reduced by 10 on both sides. Don't know what the actual CO percentages are.

Jez,

you said they were reduced by 10, so what are they now ?

C1 is 9, C2 is 10.

Notes from previous owner suggest orginal settings C1-18 and C2-19. He then tried 30 and 25, and 20 and 20. Obviously going richer was not the way in this case but, as someone here said, each bike is different.

Thanks to previous owners for keeping all this paperwork in tact . You know who you are.
