Gearing change?

[size=150]Has anyone tried different sprockets.
The mannic excelleration is great and I don’t want to loose that. But when doing 80mph revs are at 6000rpm. When doing a long trip this seems quite high to me. I am thinking of going up on the front from 15 tooth to 16 tooth OR going down two teeth on the back sprocket.

I was wondering if anyone has tried it, and what the out come is.[/size]
