hi Wilko, never thought of that although my mate does it with rearwheel sprockets, specially on his prewar Doughlas as he cannot get the parts, but where do you get the new teeth? explain please if you will
kind regards

I'm probably confused again-I "upped my" gearing by changing the GEARBOX sprocket-as engine sprockets are not available-or so I was told-pre alternator engines have a shock absorber cam- expensive to make- on the sprocket . I went over Hardnott and wrynose passes on me 350 A.J. in 1960-has it got any steeper since then??

Easy-peasy! I did both on the '29 Raleigh in 2008. (500 sidevalve-not a quick bike) Anything with a gearbox will do the trip if you remember to change down! Actually they may have made it less steep for H&S reasons and to guarantee the human rights of tour coach drivers.
Anyone here done it on a veteran/belt driver?

Industrial sprocket suppliers, just google.
