I installed the G2 and a set of OEM heated grips last weekend. The G2 makes a huge difference - smoothed the throttle right out. The only issue is that the heated grip is a bit longer than the the G2 tube so I cut a small section off of the plastic tube and inserted it after the G2 and just ahead of the bar end. Everything buckled up nice and the grips look and work great. I'll probably put my throttle rockers back on to help with long-distance fatigue. I'm thinking about a set of grip puppies as the final comfort mod for the grips.
