Hello and welcome from the adjoining west county to you
Left side is normally cooler as direct contact to the metal bars, the right side is on insulated plastic so less to drain the heat
Why are you using them now.........its not yet cool let alone cold
Pick mine up next month, hope the grips will be ok
Well, I guess that explains it. I have the same issue (left grip noticeably cooler then right). Took it back to the dealer who just confirmed that all is well without any explanation as why the right hand grip gets almost too hot while the left leaves a lot to be desired. I make it work by just adjusting the heat level once in a while but still a bit disappointed.
