Hello Chiro58
I have Barkbusters with the Storm Guards on my bike. I also have Oxford Grip Heaters installed. I have absolutely no complaints about the Barkbusters, or the grips.
Oxford makes different styles of grip. They are not all the same length. I installed the Adventure style. I think, though I am not sure, that the Adventure grips are the longest of the three.
The grips were easy to install. Follow the instructions and you will have no problems. The original throttle grip is made of thin rubber so it tears easily. This makes it a bit hard to remove.
The Barkbusters were already installed when I put on the heated grips. I found that the right hand grip was a bit too long and rubbed on the aluminum Barkbuster frame. It rubbed enough to stop the throttle grip from returning to its at rest position. Fortunately, Oxford grips are designed to be trimmable. I had to trim about three millimetres from the end to allow unhindered movement of the grip.
Three millimetres is about the width of the flange on the end of the grip. I actually trimmed about ten millimetres from the end of the grip. I then trimmed the flange from the ten millimetre off cut. Then, I super glued the flange onto the end of the grip. Of course there is no need to glue the flange back onto the grip, it just makes the grip look like it has not been trimmed.
