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.
