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.

If you clik on "Gray" you can see what I have done with my 2007 GS500. To date I have got 65mpg average and am working on getting too 87mpg next year. I have plans to run in the Lacey FE run in May 2011 and maybe the Vetter Challange in Carmell California a week after Lacey. The Vetter challange is the real test of what can be achieved. I will be using 17/33 final drive gearing which will have the GS500 at 4400rpm at 110 km/hr [70mph] which is 20% below stock at 5500rpm [16/39].
