Re: SK5 - Query re top speed and restriction
Definitive way is to see if you have decent pulling power between 7k and 9k rpm. If its restricted the revs take longer to get there as at about 6k the rate of rev increase slows, where as full power lets it rev more freely.
Try and get to 10k rpm in 2nd or 3rd. If you can it is not restricted.
