I may not have my Throttlemeister installed properly. When the temperature is below 80 degrees, it is almost useless. As it gets warmer it becomes effective, I assume this is due to expansion of the grip. I do not have a friction disc present so the twist is making direct contact with the rubber grip... I have had no response from Throttlemeister as to whether a friction disc was supposed to have been included for use on my '13 650. Any Throttlemeister users have an idea?
