Fitted a tachometer into the 110 yesterday (had one in the rangie I'm breaking, and a convenient 52mm hole in the standard 110 dash), and was busy thinking it was underreading. Then I did the maths and it turns out the thing is geared tons higher than I expected. 24mph per 1000rpm in top going by my maths, so it looks like the tacho is reading about right... The more interesting point is that either my engine doesn't rev very well or I'm a big girl cos at the speed where I think I'm revving the nuts off it, it's only doing about 4000rpm. Now I know they aren't a revvy engine, but I wasn't expecting it to be -that- low, especially when people like RPi are making comments about their cams with "all this without ever passing 4800rpm" in them, which make it sound like 4800rpm is low...
