As to conversion to a 350, is there any real benefit? isnt it just a case of slow bike or even slower bike?
As the previous owner of a VB and the present owner of a 350; that is not true.
The 350 is slightly quicker on the acceleration and they are about the same top end wise. The VB does better on hills.
I used to race my mate (me on the VB and him on a 350 BSA) and he could get ahead pulling away. Out of interest, my ariel 350 is better than his BSA 350 (but that could easily be down to me on new rings and resurfaced cam etc)
I also own a 500 single.
The 500's are harsher, vibrate more, less flexible in starting than a 350cc.
They are however quicker away, have around 10mph more usable cruise (and flat out) and, most importantly, are way better up hills.
If you are pottering around A and B roads at 50mph, then a 350 or VB is fine
