Best gear ratio, not as beaten a topic as best oil at least. Im getting 3650 at 70mph (indicated). This is fine out on the main line and 3100 at 60mph for A and B roads not bad either. But on the green lanes and around town it is less than ideal. First is going to be less than 2000 a lot of the time. One thoughts wander to the cam. I guess Ill have to face facts and pull the primary again and go down one tooth on the gearbox. Perhaps will stay with what I have and see if I get used to it. Comments?
