Besides coming up with that fantastic joke we managed to get the Bar Ends on and the Oury grips along with the front disc and caliper. The grips work really well with the tyres, and because the bars are not as wide as standard tracker bars adding the bar ends means we don't need a "wide load coming through" sticker .
Ended up using pit bike brake and clutch controls as the stock yamaha controls were too large. Also they had the mirror stem which we wouldn't be using anymore because of the new mirrors
