Won't tell ya shit. The problem occurs in the TINY idle circuit passages and pilot jets passages where the TINY amount of fuel evaporates, the TINY amount of residue left behind is sufficient to plug the TINY passages. Or, in the case of FI bikes, to a much lesser extent, the injector tip gets residue. As for volatility, good luck with that, remember Richard Pryor
