Hi Guys,
Thanks for the link - I managed to find my way to that having posted the question the other day. Was a little frustrated by some of the photos being less than informative, but it was a freebie, so I'm not complaining.
So, all I needed to remove was the R/H cowl and Robert's your Auntie's live in lover! Interestingly I watched a video on how to remove the cowl, the guys last wors were "Dont let anyone tell you it's difficult" (or similar) which it absolutely wasn't. Getting it back on is a little more challenging! Lots of stuff to line up, tabs that have to slide into place precisely. Slackening the cables was a doddle, removing the original throttle tube and fitting the the G2 unit only took a couple of minutes. The new grips went on beautifully and feel an improvement just sat on the bike in the garage.
Looking forward to reporting on how effective the G2 UNIT IS.
Once again, thanks for your help and interest.
