Heys guys the other day i was riding my bike normally, then i stopped and left it there for awhile, when i was ready to go, i turn it on normally and responded but when i tried to acceleratte i would not respond, any suggestions what this could be, i have not actually checked cause i needed to leave, but i think i have time today and if you guys have some suggestions what could it be or from where can i start lookin, it starts normal without any problems, throttle feels like its connected but engine does not respond to the twist
Is the battery low on voltage? Have you put a voltmeter on it to see that the voltage increases when the bike is running to indicate a healthy charging system. If the Charging system is failing, (stator, etc) and your battery is getting you by, it can get low and when you crack the throttle and it falls on it's face with not enough power fir the igntion.''
no, battery is brand new installed it two weeks before start riding it again, is there any electrical cable or chip that can affect this? because throttle did not felt loose, and bike starts just fine but it dont respond to the twist.
I'm pretty sure the 2009 R6 (actually 2006+ R6) use "fly by wire" throttle ("YCC-T = Yamaha Chip Controlled Throttle" in Yamaha speak). There is no direct mechanical connection between the throttle you twist and the butterfly's in the throttle bodies. The throttle cable merely turns the "Throttle position sensor (for throttle cable pulley)". That sensor provides input to the ECU, which then uses the "Throttle servo motor" to actually open the Throttle valves.
So my GUESS is that maybe a Throttle position sensor (for throttle cable pulley) issue. Or wires from TPS to CPU, or CPU to Servo Motor.
