Hey everyone, I bought an 08 XR650L last April. It's been a great bike and haven't had any problems with it until this weekend. I noticed a ticking noise while riding and decided to head back to camp. When I gave the bike some throttle, it sputtered and died. I let the bike cool a bit and was able to make it back to camp where I discovered it was burning oil. I had oil in the air box and spitting out of the exhaust. The only thing I've done to the bike recently was removed the smog gear and changed the stock front sprocket with a 13 tooth sprocket. I've easily put on 150 miles since those changes and was very pleased at how well the bike was running. My plan is to take it to the dealer and hope that it's some kind of factory defect. Unfortunately, the bike is out of warranty by 2 months, but the main reason why I bought a Honda was because everyone told me how reliable they are. I met a guy at camp that had a long history of good luck with all of his Hondas, in fact, he's owned 3 XR650's. He told me he was shocked to see this happening, especially since the bike doesn't even have 4000 miles on it yet. I'm not a mechanic by any means and I'm not trying to find a solution on how to fix this problem, but I would like to hear about what possibly could be wrong and what I can expect it to cost me. Also, is it possible that this was caused by me removing the smog equipment from the bike? Thanks for your help and input.
