[img]i/expressions/face-icon-small-shocked.gif[/img] My sons eton 90r would not start sometimes and when it did it ran rough with no power,my nephews eton 50 was even faster! After three trips to the dealer and no atv for about 2-months total I decided to check everything myself.The problem was that the 2 wires that go to the coil were loose and were making a frying sound when I tried to start.I took a pair pliers and squeezed the terminals a little and slid them back on and it started right up and ran like it was new,that was a month ago and I have not had a problem since! I even had to turn the cdi down from 7 to 4 because if he gassed it hard leaning back it would lift the front tires a little and it still does on 4. I hope this helps. Let me know !
