A friend has cooling problems (overheating in traffic) with his 650 GS. Before he has to haul his bike a long distance away to a BMW Dealer, can you Single boys suggest a few home diagnostic checks so he can be better informed and knowledgeable when he shows up at the dealer. The fan does spin freely.
I'm trying to teach him to try and do as much for himself as he can. Most people, me included, are more than willing to help you if you are trying to help yourself first.
Thanks in advance.
