Folks- I would appreciate your insight here. The best way I could think of to easily post my reports is from this link; http://www.lakeerieislands.com/k1200gt.html * I am the second owner of this bike, obtaining it at around 3,200 miles- I have no idea how it was broken in. * I change the oil religiously at 3,000 miles using BMW, then recommended Castrol oils. * This bike has a wet clutch, with a seperate reservoir and sump. * I usually change the oil be warming it up in the garage until the electric fan comes on, ~ 15 minutes. * I then using a marine oil sump vacuum for the reservoir, and then draining the sump. Questions- 1. Why do aluminum and iron remoan so high now at 18,000 miles? 2. I understand my method of warming the bike up for the oil change may be attributing to high fuel content in the sample- true? 3. Even if my method of warming up my bike is skewing the fuel reading, that wouldn't effect the aluminum and iron readings- true? 4. With readings consistantly high with aluminum and iron at 18,000 miles, should I be worried or could it still tame down? 5. What, overall, can I do to settle this bike in? Thanks! B.
