Every area of use was improved. The first thing I noticed was how incredible the off-idle performance was, and then when jetted correctly, the over rev is brilliant. It could be a bit more peaky, maybe I'll get it ported one day, but to be honest I'd never out ride it off-road, just when twatting it in a straight line!
Seriously, you'd make you money back in fuel after 6 or 7 tanks
, couldn't believe how little I'd used on the last ride!
