The first storm of the season hit here yesterday, 9 inches in about 24 hours, which for central California is almost apocalyptic. As the rain poured down, so did the occasional hill side, onto the roads. When the wind picked up it blew down trees, into the power lines. I like to say that we have 360 days of good riding weather here and 5 days of great adventure riding weather. This kind of good blow seemed like an excellent test for the new F800 GS. They say this is the bike built to ride the world, any time, any place, any terrain or weather. With no power, no internet and limited heat it was time to displace down out of the mountains and impose my self on my better equipped relations. Layering up, the GF in her car, me on the beast we set out. Blocked road and detours, made it an adventure, narrow twisty mountain lanes covered in wet pine needles and mini slides put a giant grin on my face. Then it happened. Down in the flat land, in 3rd gear and at 40mph the bike died, just stopped firing. It seemed like water in the air box. I grabbed the clutch and stabbed the start button. The bike restarted. I down shifted and kept her at higher RPM (around 4k) and carried on. Three more times, all at low rpm and low gear the bike died. So the question is: Why? I have a few possibilities. 1. Poor design in the air box, water is getting into the cylinders. 2. My bike was made on a Monday after a long weekend (this would explain why the license plate light fell off after 500 miles and had to be lock nutted back on) 3. The 8 hours in the rain prior to running, when combined with the rain I was riding in wetted down the air filter and was restricting airflow. 4. There is some strange unknown electrical or mechanical flaw that I have not thought of. I did go down to the mechanics and they plugged it into a GS 911 tool. No faults on the system. Thoughts? This bike should not have an issue with rain like this.
