Purchased 1 of these for my bike. Leaked like a pig. Ordered a 2nd one and the threads on the nut were junk. Used the nut from the first one and got one good valve out of two. Two rides later the 2nd valve leaks like a pig. Buy the genuine Honda one if you can. Not a rookie here, been running M/C shops for 30 years.

This part was guaranteed to fit my tank, but it turns out the threads do not match and I could not use it at all. Disappointing to receive a part that did not match it's description.

Looked everywhere on the internet and found this one, all others where much more costly and does the same time, turns your fuel on/off.
I can buy three more for the price of one.
