OK, this isn't exactly 'vintage' track. But I'm thinking of riding at the St George clubday in a couple of weeks and wondered what gearing Nepean requires. I'll be on a modern YZF250 (though might take the 1980 RM250 as well).
Is Nepean similar to Canberra, or a bit longer/faster? I'm running 14/50 for Canberra which works OK for the longtrack configuration there, that's about 2 teeth taller at the rear than stock.
Any ideas?
