[QUOTE="PA1195, post: 562384, member: 2660"] You're likely experiencing heat related fuel vaporization in the tank and fuel injection system. Your Cal spec bike collects any tank fumes in a canister and recycles them through the engine intake. It's a product of Green legislation we don't have to deal with. That may temporarily lead to too much fuel vapor for the engine to burn. It also has some other plumbing the other 49 States don't. One thing to try is crack the fuel cap before firing up to briefly let off tank pressure if you think there's a chance of vapor formation. Extinguish all smoking materials and watch for any static source before opening the filler cap. Might not make much difference. But do try carefully opening the throttle some when starting to purge any vapors and add some more air. See it that helps clear out the fumes. Watch the idle rpms until it settles down. Also, your fuel should be formulated for a different vapor pressure than that sold in lower/cooler climates. If not, it can cause problems. Can't remember when I last saw 110 deg - never in Alaska except in a sauna or hot springs pool. Gary in Fairbanks [/QUOTE]
