Have one of these fuel caps on my Beta 500RS, got a 24 Beta 300RR Race and the cap leaked like a siv. Recieved this one in two days after ordering, put it on and no more gas leaking out around the top of the tank like the stock cap.
Slow shipping and the o-rings were all in one bag. It would have been nice if they were separated by part numbers to help identify instead of guessing or measuring. Other than that I got what I ordered and needed.
