I'm currently running Mobil 1 synth with a K&N filter. I'm planning on switching to Rotella on the next change.

When switching to synth, the only thing you have to worry about is switching too soon.

The issue has to do with the clutch plates, not the gears or engine. If the clutch plates are not worn in enough when you switch to synth, then the plates won't catch when you release the clutch. This happens because the molecules in synth oil are more "uniform and slippery"... If you're on a dry clutch bike, then I'd switch at the first change. My 250 got switched at about 3500 miles.
