Tach Troubles, electric boogaloo. After doing lots of careful research, I have learned 2004 Kymco Super 9's are famous for having their tachometers go bad, so after alot of trouble shooting (such as using the same as stock spark plug) or looking for pinched wires, I found this. and just fyi if you ask if its trying to return to 0, if I return the needle to 0, it goes back to where it was. Any thoughts on this guru's of Kymco Forum. Has a solution been found? and yes Im using the original spark plug, here's a video of the tach here:
I tried returning the needle to 0, but it always returns to where it is, and jumps around. I'm leaning towards bad signal or coil touching. Thanks for any advice guys!
