R80 GS running hot
I installed one of the thermometer dip sticks before a 3500 mile trip. I noticed that doing 70mph for more than 20mins would lead to a temp of 125°. I cross checked with a friend's thermometer (different manufacturer) and I get similar readings. The pipes are blue to the first bend. I tried changing the fuel mix in the carbs but with no success. It's back at the manual recommended 3/4 turn out. The only other unusual thing about the bike is the exhaust is loud. It's a Keihan stainless which was added less than 3 years ago. I suspect the previous owner ran a rod through it.
It get good compression from both cylinders. The bike pulls fine. It needed roughly 1L of oil in the 3500 miles.
Anyone had a similar problem? Ideas appreciated.
