'21 but mine feels like its running Leigh

Waynes 18 was flying at LLandow.
I didn`t get to ride it unfortunately, but it was comparable to the 300, as I said though, the 300 had 210 mains & I didn`t adjust needles, etc.

Your 21 was quicker / more powerful than my bike though. I thought it would rev higher & be more peaky, guess I`m more used to 4 stroke 600`s & 1000`s these days.

It felt like a slightly more tourqey version of my 300.
