Barry,

To chip in another two penn'orth into the fray...

A quote from Avon's Motorcycle Product Manager:

Empirically, I continue to run 36/42 on track without problems. Why should I
change?

What I would definitely recommend is that you write to the manufacturer and
ask them. They're usually only too happy to advise. Then it's (usually) a
matter of deciding whether to follow advice or fashion!
