like you all, if you have them why not use them, it just another layer to prevent something from happening, I did hear something about a slight concern of taking up a little of the vent used to cool the engine.
Why wouldn't you use them? TBH though the props haven't moved a bit from when tightened up. On that note, I notice the black ones screw down quite well to about half way then become quite tight to turn on. The silver ones spin all the way down. Is this the same for everybody else?
It's a bit special, I moved to another country between getting my I1 and the locks being available, so that I never got the ones my dealer has likely sent to my old address.
Didn't find any locally yet, and couldn't be bothered to order some overseas, I'd rather get the new locking props when available...
