Hello everyone...this is my first post. I recently purchased a 1998 Concours. It has 30,000 miles on it and runs great and was very well maintained. It looks mostly stock except for a few minor add on's. My question is I don't want to have the "hydrolock" problem. The petcock looks original and I don't think there are overflow tubes installed.How would I go about having them overflow tubes installed? Please advise, thank you, Bob from Appleton,Wi.
