Given the vast improvement in power and torque since tweaking the mixture back to where it should be, i'm pretty confident i've found the problem but obviously time will tell.

You are probably right Dave, perhaps it isn't that likely a cause. From a 2 stroke background it is one of the first checks one would do, often just to monitor the health of a motor. When we ran a Yamaha 702 jet-ski I probably checked the compression once per month, but then it only took 5 minutes. With a 2 stroke it gives a good indication of how healthy both the top end and bottom end are.
On 4 stroke bikes I find it handy as well - again it tends to be easy to apply - my bikes are all singles and twins and the plugs are generally easy to get at.
As you will remember with the RB, a compression test (plus the little gas sniffer) was instrumental in diagnosing the current malady.
I hope your latest tweak has fixed the problem and you get back to that very impressive 27 MPG Dave :-)
Stay safe.
