Dinqua,
Many thanks for info, sounds promising.

....it's a snap with a bucket and a 2x4.
The bucket part I understand ... the 2x4 I'm afraid I don't, perhaps my English doesn't stretch that far (or arithmetic) 
The mileage you mentioned at those speeds seems pretty good, I take it's the ratio/lower RPM's that are responsible for the improvement?
Given that I also have the SM (865cc version) how does the belt feel compared to the standard 16 tooth sprocket?
I know you said it feels like an 18 tooth sprocket, but does it lose much in terms of initial acceleration from standing (I am sure it is an improvement at highway speeds)?
Again many thanks.
