Issue with K3 on the overrun
 

Hi,

my bike is a K3 with a CCC end can. Over the last 2 days, I've had a strange problem that is a little concerning!

Upon reaching, for example, 70mph in high revs and then backing off the throttle completely, when the bike is slowing I'm getting a strange 'bump bump bump bump..... as if the engine sgetting a small increade in revs. I can actually feel the bikes movement (slight vibrations) when this is happening.

At first, I though I had something stuck in the tyre. It happened again today. Always at higher speeds, throttle completely released. Any ideas what it could be? Should I be worried? I don;t think it should be doing it!

3200 miles done so far.
