Hello. When a 1985 VF500F reaches it's top speed, is it: 1) Not geared high enough? (RPM maxed in 6th) 2) Out of horsepower? (Thrust is equal to drag) Just wondering since they seem to offer a bunch of rear sprocket gearing options for this bike. That & I don't want to have the motor turning too high at highway speed. I don't know because I am still waiting on the guy to get the new title so I can buy his bike. Thanks. PUNISHERGTO
