            Twitchy throttle control 
            
             Kev's latest mod. 
             As most of us know the XT660 is hard to control in traffic conditions, tight corners or traffic circles. So I have come up with the mod which can be applied to our XT's. This is a very clever mod & works well if you want more throttle control, I found the idea on the net. I lowered the cable by 1mm in the grip to try it out first, day 2 of testing I went a further 5mm around the throttle to 20mm, it now has so much better throttle control at low speeds.         My final depth is 2mm deap after testing.   I used a 2mm drill bit to cut the groove, I used the edge of the bit to do the cutting not the tip, I rolled the grip along the side face of the drill bit to keep the circular angel of the twist bit.             On day 2 of testing I have now cut the grove 20mm along the grip to give me a reduced diameter up to 30% throttle opening.
