Dropped my bike for the first time and this little rubber piece came out... can’t seem to find out where it goes... it has 41 labeled on it but I can’t seem to find it.
Yes it should be there. It prevents the tank from coming in contact with metal, which will eventually damage the tank with all the vibrations. They just pop in/out. It happens from time to time. Could have gotten partially popped out last time the tank was up. Just remove the nut at the top of the tank right behind the top triple clamp, and the tank will pivot up. These bikes come with a little prop rod to hold the tank and with its age, it is likely missing. Find something to prop the tank open with and wiggle the plug back into place.
