I am used to riding old British bikes and am concerned that my riding style is causing me problems. North Yorkshire and very undulating roads are just across the river. I went for my first 50mile run the other day. After 5 miles I was riding down a road that felt basically flat, in 6th gear (I have a habit of moving through all the gears as soon as I can) doing about 40/45mph when the engine staled. A bit of a panic because I could not change into a lower gear before I stopped although the engine would rev between gears. This happened again a few moments later but then I had 45 miles of very pleasurable touring. My question then, is my riding style (too high a gear) causing the stall, could there have been a simple glitch in the fuel supply or something ales?
