Ducati next, and that has had shitty CA gas in it....boo.
A friend fucked up his 748 by leaving petrol in it, although that was for years as opposed to months. It was an early yellow biposto (P reg he bought new) and eventually it must have sat for nearly a decade with little if any use (a series of divorces, failed relationships and general not having a fixed abode!!!). He said the pump in the tank just got gummed up and completely fubar’ed.
New E10 fuel kills carbs in under a month, and thats with decent quality parts inside, viton o rings etc. Unless your bike is in near daily use, at least weekly you have to drain carbs out as best poss, but even then fuel line still decays quicker than usual.
