I pulled the heads off my brothers 2001 996 to check the valve clearance and look at the rockers.... Bike had about 5000 miles on it at the time. Both of us have built engines and road raced for many years, but have never seen the following.
When I pulled the heads, on both cylinders the pistons were perfectly clean, I mean shiney clean. It looked like someone put new pistons in it the night before!!!!!!
In my race motors, running VP or Sunoco race fuel there was a light grey color on top of the pistons, but never perfectly clean pistons. Strangest thing we have ever seen.
Any similar experiences????
