There have been several reports of people having an oil soaked airfilter, some as low as 10 hours, others well past that. Reports are of oil sitting in the intake area under the throttle bodies, and oil soaking the filter element itself, restricting airflow, reducing top speed and RPMS into the 9000's.
New air filters are $120+, and not many have succeded in getting it covered under warranty from Yamaha (although I know of a couple who did recently).
Two things seem to be common in these cases so far, althought they *may* not be related.
First, several owners have reported elevated oil levels, either from the factory, or by overfilling from an oil change, both by themselves and from the dealership service.
Second, the 4 pressure lines at the intake and at the pressure sensor have come a bit loose. These appear to me, to be vaccuum lines, and I honestly don't know where the oil system comes into play on the inside of the intake in relationship with these lines. But several owners have reported the oil leaks at these lines, specifically where they fit the intake and pressure sensor.
It it highly reccomended that owners take off the air filter cover, and inspect for any oil, both on the filter, and pooling in the intake itself. Adding small zipties to all the lines in this area wouldn't be a bad idea either, to try to fix the leak. Unfortunately it is such a small fitting that even small zip ties won't secure them 100%, if they are under any kind of high pressure - however it may help.
