I have an 09 800GS. The original owner, a stand-up guy who is a regular on this forum, fixed a leak in the lower case with JB Weld that has lasted almost two years. It started to leak again 2 months ago, so I wire wheeled the paint and some, but not all, of the JB off and replastered it with more JB. I was ecstatic that I stopped the leak. But, alas, the leak is back. Smarter folks than I tell me I should find a welder who can weld aluminum, as apparently that is somewhat of a specialized art. The original leak came about when the bike crashed on its left side. There are two connection points for the crash bars on the lower case. The impact caused a small tear in the case right where the crash bars connect, and thus the leak. Any of youse guys have any thoughts on the matter?
