Keeping to 30 mph speed limits

[Spitfire]

Hi guys,
           I know I need to synch my carbs but trying to keep the old F1 under the 30 speed limit is not easy, it likes passing through 30 as I accelerate and change gears but certainly does not like cruising there, I'm up and down the gears with my nose on the speedo.
I remember having the same problem in the olden days but there are so many more 30 limits now, anyone else have the same problem with their bike ?

Cheers

Use a lower gear. Sounds nice too!

I also use a lower gear for 30mph driving, my 400 is not happy in top at 30

The Advanced Motorcyclists train you to select a lower gear and to use the engine note as an indicator of speed. This saves having to check the speedo every 10 seconds!

I use 3rd for 30, 4th for 40 and fifth for 50 (on the Triumph)
