Sorry Kelvin,
I have been assured that the cap doesn't quite seal due to the taper of
the aluminum.

I hope you can clear up my confusion over the fuel cap problem.
I have the old 70mm cap and flange supplied with my XS kit around 2001
- not yet fitted.
As you stated it has the tapered edge to the cap measuring 70mm at the
max diameter and the receptacle flange has a similar taper.
Around 2005, I purchased a locking cap from Europa which is indeed
65mm max diameter due to the tapered edge having been machined square.
However, having measured almost every dimension on each cap with a
digital vernier, I can find no significant difference between the two
caps.
The O-rings are the same 57mm x 3mm size and the O-ring groove and
position on the cap result in identical O-ring position and dimension
when fitted.
The O-ring sits in exactly the same position on the receptacle flange
when the 65mm cap is fitted and when tested to 10psi there was no
leakage from either cap.
The only difference would appear to be the gap around the cap when
fitted to the old type receptacle caused by the square machined edge.
Am I missing something.
I know some are reporting leaking caps but could this be due to the
cam mechanism being incorrectly adjusted to obtain an effective seal of
the O-ring.
