I am with David Anderson that the optimum engine sprocket for the VH is 22T. Mine is currently 23T but the (1937) bike will happily cruise at 60mph if I want it to. Son Rob has found me a 22T sprocket (to replace my old one which has ended up on his bike) and I will fit this next time I have the primary side down. In the 1970s I ran a VH on 22T which had higher top speed than when I went to 23T, just as David says. The other advantage of 22T is better acceleration and a more nimble bike on local lanes.
