I have a 2005 Suzuki DRZ 125L. It has been running great all summer and now it decides it does not want to cooperate. I can start it but when it idles it idles really high. Also, when I put it in gear and give it some gas it will go but as soon as I go more than half throttle it dies off. The only thing I have tried is replacing the spark plug. Please help me.
Thanks,
J
