The small print in the law says it's ok to pump your own if you are on a motorcycle or if it's diesel. 
Hey, you're right. I didn't know they had a motorcycle exemption. I thought only diesel was exempt at a retail gas station.
From here, as of 2011 :
http://www.leg.state.or.us/ors/480.html480.330 Operation of gasoline dispensing device by public prohibited; aviation fuel exception. An owner, operator or employee of a filling station, service station, garage or other dispensary where Class 1 flammable liquids, except aviation fuels, are dispensed at retail may not permit any person other than the owner, operator or employee to use or manipulate any pump, hose, pipe or other device for dispensing the liquids into the fuel tank of a motor vehicle or other retail container. [Amended by 2001 c.285 §1]
And a few lines down is the motorcycle exemption :
480.349 Use of gasoline dispensing device by motorcycle operator.
(1) As used in this section, “motorcycle” has the meaning given that term in ORS 801.365.
(2) Notwithstanding ORS 480.330 and 480.340:
(a) Upon the request of an operator of a motorcycle, the owner, operator or employee of a filling station, service station, garage or other dispensary where Class 1 flammable liquids are dispensed at retail shall set the fuel dispensing device and hand the discharge nozzle to the operator of the motorcycle.
(b) An operator of a motorcycle who is handed a discharge nozzle under paragraph (a) of this subsection:
(A) May dispense Class 1 flammable liquids into the operator’s motorcycle.
(B) Shall, after dispensing the liquids, return the discharge nozzle to the owner, operator or employee.
(3) The owner, operator or employee who is handed the discharge nozzle shall return the nozzle to the pump or take any other actions necessary to ensure safe completion of the fueling operation. [2001 c.344 §2]
Note: 480.349 was added to and made a part of 480.315 to 480.385 by legislative action but was not added to any smaller series therein. See Preface to Oregon Revised Statutes for further explanation.I looked into it awhile back, and even completed the "training course" to be certified to pump gas at card lock stations (just a list of common sense things), and I didn't see any exemptions to pumping gasoline into anything at that time - Thanks Tom!
I have encountered one station where the owner insisted I move my bike away from the pump, and tried to insist he would pump my gas. I told him that would never happen, and to give me the nozzle before he offended me. He did relent, but complained about it. I haven't been back to that station since, which is a shame, because it's the only station in the PDX metro area with non-ethanol 91 fuel.
