When you shut down the bike after bringing to operating temp, the fan will run for awhile. That was one of my clues that something was wrong with my bike. You can use ECM Droid to manually turn on the fan. You can also disable to the exhaust valve with ECM Droid as well. I think its called the IAV. Double checking and cleaning the grounds on these bikes is never a bad thing. You may want to run an auxilliary ground wire from the battery to the coil. Some people swear by it, I think I noticed a minor difference when I did it on my last one.
