I have a 2007 polaris sportsman 800 stealth edition and took it riding for the weekend for the first time since i bought it. The bike is in excellent shape very low hours and miles. 30 min into the ride i went over some small bumps(really slow) got back on the trail started riding and started to hear a sqeaking noise everytime i started to accelerate? I could not pin point exactly where the noise was comming from nor could i see anything wrong under the bike. I washed it immediatley after i rode and started it up to pull it on the trailer and no squeaking noise?? Could anybody tell me what possibly is the issue?
