Rider weight significantly above the 10 1/2 stone / 70kg / 150lbs sort of average that would have been found in the 1940s.
engine down on power - yes
hilly terrain - yes
I'm more like 220 lbs
I know I need a top end overhaul. In the meantime, I might try going down to 17t to see how that goes. Its not like I'm going to go on any highway trips - I have plenty other motorcycle options for that.
I remember the first time I rode my WM20 it revved it nuts off at 45mph it was fitted with a 17 tooth engine sprocket, I have now changed this to a 21 tooth bike will now cruise easily at 55mph with a nice relaxed ride I have seen 65 mph with this sprocket fitted but then its revving hard.Only the steepest on inclines will slow it down enough to warrant change down to 3rd.I wouldnt go back to std WD gearing...Dave
