[slo coach]

I have read on a bandit carburetter site a detailed account account of the different air/fuel ratios and cannot remember where i spotted it.HAS ANYBODY SPOTTED IT?.It talked about a 14/7 ratio for one set of riding conditions and 12/7 from memory for another type of conditions with posts from riders commenting on the different fuel economy offered by the different settings.i think from memory that to drag the bike to the max the ratios are way different to touring settings where economy is preffered.so has anybody seen the info?????
