hi, i know this sounds weird but only being the proud owner of a 1980 cb650 honda for a week and no manual. can anyone tell me why on the speedo dial in the right lower corner there is a red light that keeps coming on/ what is it? the shop told me it was oil pressure another told me it meant my filters needed changing etc. it has a oil light between the speedo and rev counter so not sure. thanks if any one can help a real novice
