I swore people have gotten clutch replacements under warranty!? You may want to research that a bit more. There are some dealers that are a pleasure to work with and some that are nightmares... might be good to research as well. If you need to take it further away for a free clutch it would obviously be well worth it! At least act on it if you are still within the 3 Years!
Dont like to link NAM threads over here, but I couldnt find anything better...
