I got less than 50 mpg today, always got 62+ before, up around 70 on a run,
maybe a plug or a coil has gone bad, or I got bad petrol somewhere, though I usually fill up at the same place,
my bike feels like it's not running well either, likes it's misfiring or something, or maybe it's all in my head,
I'll let her run this tank out,only a few bars left, refill with fresh petrol and check again,
brakes aren't dragging and trye pressure is all fine.
