I own a 2016 VFII Redline in Manual. It's been virtually trouble free for the two years I have owned her. This Christmas I had my Uncle start the car in my garage and the sound upon startup was a loud mechanical clanking noise which lasted a couple seconds and then went to normal idling sound. I let the car idle for about 30 seconds, turned it off and restarted her but the second time round the sound did not occur. I left the car in the garage and started it the next day and the same clanking sound happened again and then went to a normal idle within seconds. This time I took the car for a short drive and everything seemed normal. Since then I have used the car and the sound has not returned however it has left me quite concerned as I have no idea what it was and if it caused and damage. One possibility that may have caused the original sound is that my uncle may not have pressed the clutch in all the way in or released it too soon upon starting the car. He is a bit shorter than me and didn't adjust the seat when he got in. Any thoughts??
