injected R1 co vol' adjustment
Just been looking through the R1 workshop manual and found that you can adjust the co vol' via the clocks/diagnostics. Its done cylinder by
cylinder. So is this the same as adjusting the co% and how do you know how much to adjust each cylinder? Can't see how it would work! Any
ideas?

Buy a power commander, it will save you lots of hassle.
If you want to tune the car yourself, also fit a wide band lambda sensor and gauge and you can alter the settings yourself.
I will be using the PC and an Innovate gauge on mine.

Yeah, I'm going to use a power commander. I was just getting to know the system when I saw this and was curious. This would adjust across the
whole rev/power band anyway. Just can't figure how you can adjust each cyl' when you can't read the gas for each cyl
individually?

i think the original front pipes may have ports in each header to measure the co for each cylinder. they are bunged with small allen bolts, i think.
i have seen this on quite a few different bikes

Adrian, yep you're right there is a mixture adjustment that you can access via the diagnostics, but its a very simple system of numbers denoting
how much the map gets enriched on each cylinder and I think it is indeed a blanket setting across the rev range so not really useable for anything
other than crude enrichment if you put on a free-er flowing air filter for example.
If you decide to play around with it (I wouldnt bother), at least make a note of your engine's set of numbers so you can return it back again,
and adjust them the same all the way across (ie add 2 to each figure). Don't even them up to equal the same number though as they are usually
intentionally different to compensate for hotter temperatures on the inner cylinders etc.
BTW Rich, I think you're thinking of the AIS valves / ports for allowing air into the exhaust to affect overall emissions, but I dont think
you'll see any engine with 4 individual Lambda sensors to actually measure CO from each cylinder.

Cheers Chris, thats what I thought. Didn't intend to adjust it but as a mechanic was just curious how it could work.

the front pipes i have seen just have allen key bungs in them blocking threaded bosses which i pressume the factorys use for initial set up and then
block with the allen bolts.
