That's what I figured. To the shop it goes then. I just don't have the patients to do much mechanical work. Does anyone know where to find the radiator cap on the '06 GW? This has been my only issue with this bike. Love the way everything is concealed but can't seem to get to anything to work on it. I like to have never got the cover back on that I had to take off to check the coolant. I think the floorboard and heal/toe shifter had a lot to do with that though.Hi Rainbow Island, I encountered that problem before. For me it is a booger to replace it.
