It only does it under load! It revs perfectly smooth when stationary. I haven't done any work on it at all, is there an easy fix for the fuelling issue? Thanks!

https://www.youtube.com/watch?v=hgTSGsTsBJI Hi Guys! I've had this bike just less than a year now and I was out riding when all of a sudden it started doing this! I can't get any higher than 15mph and I can't work out if it is something I may have knocked or if it's not as simple as that!? Any help would be gratefully received! Matt
