Agree with basadia. I've just fitted an NEP, ( thanks Mal ) and works a treat although some mods were necessary. As basadia did, I cut the 'flange' off of the inner side of the grip. As Mitch mentioned, it hits the tank on a righthand lock, so I pulled it apart and assembled it so the lever is up now and not down. The lever is in a similar position to Brocks photos above, although mine is a 1300, so, mine is in it's 'off' positioning in a similar position to Brocks 'On" position and visa versa.
