Could have been the corndog...anyway - stopped at the 76' station for fuel. They were out of 91 octane - had 87 & 89. Filled with the later. Uly don't like anything but 91 in this unusual 90* Oly weather. Started pinging just like my stomach. Got to thinking (not well, due to the corndog galling out my innards) isn't 89 just a blend of 87 & 91 ? If so, wouldn't they be out of 89 too?? I don't know the gas station business, so my assumption could be erroneous. |

Jphish- that's what I've read too. Stations only stock two grades of gas and blend them to get mid-grade. Maybe they were running low on 91 octane and disabled that selection on the pump so they could stretch their supply? |

That would be it. Usually I just pull the bag off the nozzle and pump what I want. I did have an attendant run out one time and tell me that "we are out of regular" (this was for a car, some stations will block off the regular nozzle in order to sell the more profitable "mid grade"). I just laughed and pointed out that I had just filled my car from their empty tank...I then pointed out that if they have mid grade they have to have regular. |

Rwven, I would have told them,"There is no way that I could owe you any money then". |

Like loves & fishes...gas from an empty tank. I guess miracles do happen...should be free of charge. Yeah Hugh, You only see 2 tankers on a semi load - so surmise that it's 87 & 91. (unless tankers are compartmentalized) Your theory of stretching supply could be right too. Either way... Uly don't like 89. I can get away with it in winter - but not summer. I'll check with the weights & measures folks & see if there are in fact only 2 grades - I'll post what i find. I think the corn dog was 110 AVGAS. j |

I have been using only the top grades..well, 91..think I was told to do that somewhere down the line, always did that for the roadking, no issues what so ever.. AS for pinging..can't hear the damned engine for wind noise, so no idea.. Ordered the Brackets for the windshield..will see if that helps.. |

I got the Palmer brackets with a 16" Parabellum. Works pretty well. Like the ZG+4 too - but the Para is about 4" wider and provides a little better bug protection for the insect season we're now in. Still gotta wear earplugs though...not for the bugs...for the noise. j |

All I ever use is 89 octane gasohol. Works for me. |

I accidentally put 4 gallons of basic Exxon gas into my '07 H-D Street Bob yesterday. They say it "demands" high-test, just like the Uly. I'll let you know if causes any problems. I guess it technically makes it 4 gallons of 87 and 1 gallon of 91. |

It all depends on many factors including your bikes timing, ambient temperature, and throttle, but my first 06 Uly hated 87, and my current 06 doesn't mind. |

Most fuel tankers have different compartments for the different fuels. They run 3 or 4 compartments, with dry bulkheads separating the different fuels. There are actually 2-3 inch spaces between the different compartments with nothing in them but a vent in the top and a drain in the bottom. If a compartment starts leaking on the end it will leak into that compartment and out the bottom. An inspector one time was under a tanker that had a leaking bulkhead. The inspector found a piece of debris blocking the drain hole, she poked at it with a pencil and the fuel that came out hit the bulb on the work light she was looking up into the drain hole with. The garage was a total loss. Water can get into fuel may different ways. Hopefully the filters are serviced regularly to prevent water and other contamination from getting to the nozzle. |

I haven't run super in years. My ULY,wife's XB12Scg,KX250,Banshee,cars and trucks.....I'm in Maine and deal with E-10. No preignition or detonation. My personal theory is in my area at least people dont buy much super so it sits in the tanks and gets "stale"on the other hand the regular rolls over much faster so its fresher. my .02 |
