We have a 1997 Yamaha Waveraider . It starts great, idles great, and runs great, until I try to run it wide open. It will do about 35 kph when it should do about 55. I've had it looked at and was told that the compression in all 3 cylinders was good, but that the 3rd cylinder was not getting proper spark. Is there a coil for each cylinder on this thing? Any other thoughts?
