I so need a rev counter. I'm in third on the high street...! No idea of revs - what will a '55 carb rev to comfortably?



Try it. Get the engine up to temp. first then just twist the throttle until the rev-limiter kicks in!!! Do this in 2nd and you should see the figures I quoted above. If it struggles to hit the limiter, you probably need to increase the size of the main jets. Prior to rejetting, I hit the rev-limiter once and I had to be brave with the throttle as the bike sounded like it was gonna blow. Based on Pat's thingymajigger, I put some 126's in and the difference (from 6k rpm +) was night and day.

The only problem with the OEM rev-counter is the location. You have to look down to see it. Personally, I'd prefer the 2 clocks (tacho/speedo) to be reverses in both location and size.
