[QUOTE="RossKean, post: 1444922, member: 19880"] I was referring to charcoal canisters generally present in many vehicles including most cars - not specifically the California version of FJR. There are good reasons for NOT running winter blends in warm weather - not the least of which are volatile losses and fugitive hydrocarbon emissions. Vapor lock can be a real issue and problems with saturated charcoal canisters (on FJRs) are documented (even with regular fuel blends). Problems with fuel "boiling" in the tank are far more likely with winter fuels. (I seem to remember some cases of fuel "fountains" with Gen I bikes with hot engines parked in direct sunlight.) As I mentioned, I don't know how the summer/winter blends affect CO/O3/HC/NOx emissions but raw hydrocarbons making it to the atmosphere will be higher for winter blends in warm weather. Interesting side note - I bought by '07 slightly used from a guy in Connecticut (he bought it new from a local dealer). Despite its east coast origin, it was a California model and I experienced saturated canister related starting problems a couple of times (parked in direct sunlight on a hot day) before I elected to bypass the canister.
