i have a k6 gsxr 600 with around 7500 mi. Today when i was starting it i flipped on "on" switch and it seemed like the pump sounded really weak and the rpm needle was twitching out and the neutral light was dimming out. It seemed like it had a very weak battery, but it started just fine and then everything was normal. This is the only time it has happend. Any idea what the problem could be and should i be worried for future references???
