Brother Reuben

i've only had this bike for about 2 months, so i still don't know alot about it. seems when i drive uphill the oil light comes on. this could just be a poorly placed sensor. [same thing happened on a chevy truck i had, fuel gauge read empty eveytime i drove downhill] i recently changed the oil and filter; the oil level is good, and there are no leaks. something i have to live with? or sign of a problem.
