yes i do realize what im looking at and i realize the cams go across the motor. what i was referring to when i said the left side was the timing chain as a starting point as to which to label the cylinders in succession, 1-4. i misstated that, my fault yes im also aware of the need to have it tuned. a generic map, while not preferable, will allow me the leisure of time until i can have the bike dynoed and tuned accordingly. this thread also is not about me putting a pc on or a specific question about one. its about me trying to figure out why one cylinder is getting more gas than the others. it may or may not have anything to do with the pc. thanks for your input tho
