When conserving fuel, I find as long as I up shift at 5,000rpm and at lower speeds keep her at about 4,000rpm I get really good economy without labouring the engine.

I increased my front gearing from 16 teeth to a 17 tooth sprocket, and this has resulted in about a 300rpm decrease which has made doing highway speeds more economical.
I am presently working on a pair of aluminium Cargo boxes that will fit close behind the riders legs above which I will mount a long tapered cargo bag right behind the riders back, in the hope that I can get to 87mpg. I have also bought a new rear tire [Dunlop D404, 130/90 - 17] that is 7% larger than the stock tire and will bring the rpm at 110 km/hr [70mph] down to 4100rpm. If this all works as planed then it will be worth going to Carmel California [2500km from here] and the Vetter challange!
