I use heated grips on my bike, it's handy especially on long rides, so I take the throttle under them too. Found some info on this recently, was looking for best speaker upgrade for street glide and found how to choose the throttle.
I remember a conversation with a friend who used to ride back in the 60s. His comment about all the "goodies" we have on our bikes today... "you guys are spoiled". My answer, "Yes. We enjoy all the goodies because nowadays we ride FURTHER AND MORE OFTEN"!
