I've been filling my tank, topping it off until there is fuel above the vent hole for three years. Please tell me how this is damaging my motorcycle. I'm sure this will be good conversation, quite frankly the craziest thing I've heard in a while, fuel volume affects ECM, hmmmm ....... must have been a good crop of green in southern

I can't recall where I read it but I'll try to find it. I do know several people have reported on this site that after over filling their tanks on late model fuel injected bikes they went into limp mode. It may have something to do with a clogged overflow or fuel blocking the vent when topped off.
Ya gota love these forums! Where else can people come with problems only to have the clueless insult those who try to help? Let's see what was the failure mode and what a coincidence that it happened after refueling? Hmm brand new bike no problems then he refueled it and it went into limp mode...I suppose the experts are going with the "Gee I guess your connectors corroded on your new bike while you were getting gas " mode. After all it's three weeks old now and they don't last forever you know. And because they have never heard of a problem with overfilling (not overflowing for you slower readers ) that can't possibly happen because they know every possible failure mode with Harley / Delphi electronics. That's like saying the world isn't flat, I mean that's just crazy.

as crazy as it sounds, it can be the gas cap. if it isn't venting properly, it can throw a code.
friend has an hd trike. she fills up at the gas station. upon riding off, check engine light comes on. she's in a hurry to get to a function so she ignores it. rides over 30 miles to the function. stops. comes back out, light is still on. i ask her when it started, she tells me right after she got fuel. i loosen the cap, put it back on. she restarts the engine. no cel.
i'd heard that before but never really believed it. but having seen it with my own eyes. okay, i'll give it a shot. after all, its not like it is hard to remove and replace the friggen gas cap..... (okay, maybe for some of you it is
)
