The hot grips on my ST4s have started to play up. Admittedly they are quite old.
For some reason when they are turned on they sit at the coldest setting as they are supposed for a couple of seconds then switch themselves to the hottest setting.
Easiest answer is buy a new set and be done with it. I read somewhere that poor wiring connections could cause issues but everything seems ok.
Just putting it out there in case there is a fix that doesn't require stumping up $180 for a new set.
