I installed a set of Kawasaki OEM heated grips on my 2011 Versys. They are not working as expected. They provide barely adequate heat in the highest setting. My previous experience with heated grips is that they get uncomfortably warm in the highest setting. I verified that I followed the installation procedures to the letter. Has anyone had experience with the OEM heated grips? Is there a way I can test / verify that they are working properly?
