I used this “cap only” to rebuild a 18 year old cap on my F1 Rocket. The old cap over center feel was getting a bit numb. The new parts fit beautifully and now my caps work like new. A 5 minute job, should have done this sooner.

I like this fuel cap. It sits flush, is adjustable (for the tension of the latch) and seals well, Still, I was hesitating between 3 or 4 stars. Spare parts (O-rings) are available but the weakest part is the small pin that keeps the mechanism in place. This part alone is not available. Without it, nothing holds together. I had one failing while I was at a remote airport, Fortunately, i fou d someone over there willing to help and he sacrified a 1/16 drill bit that we broke to make a temporary pin and allow me to get back home. The pin should be offered as a spare part.
