Hey guys new to the site but wanted to give an update on a machine that has 2000 miles on it. Purchased in May, but have rode the crap out of it, nothing rough other than some good old Kentucky trail riding. Kept air filter clean, changed oil three times already, and greased every other ride. Diff oils changed and all looked good. I was a very happy with my purchase. This weekend at the end of my ride I was almost home running about 50mph. All the sudden the engine started knocking. I shut off immediately and towed home. Checked my overhead (valve adjustments, chains, rockers ect.). No problems. Still under warranty so taking to dealer in Tennessee near Brimestone ATV Park. I purchased from dealer in Louisville KY but they suck. Wish me luck guys hope it's not a rod knocking at 2000 miles!!!
