Well my F8 is going into the shop with only 2500 miles on it. The stalling is progressively getting worse so I called my local dealer that I purchased it from and they said they have seen the exact symptoms I am experiencing on a few other F8's and it is one of two things. 1. the computer needs updating or 2. there is a fuel sensor that can become faulty so when it heats up, the bike quits. They are going to update my computer and relpace the sensor. Hopefull this resolves the issue.
Other than this issue, it is an amazing bike!
