My 2012 S10 was recently in the shop for clacking engine noise. The good news is that it appears to be resolved and the bike sounds normal. The bad news is that I'm at a complete loss to understand how an engine oil change could have fixed the clacking.
My S10 sounded exactly like Belaflek's in this video: https://www.youtube.com/watch?v=qW_b8RJCddM
History: Bike was running fine in early May when I rode it up to Romney and back. Afterwards, the bike sat unused for 2 months. A few weeks ago, I tried to fire up the bike and it would not start at all. After repeated cranking, the bike finally got started up, but there was loud clacking and the bike sounded like it wasn't running properly. Both cylinders were firing as the exhaust pipes were hot, but then the clacking settled down to what sounded like normal idle. A small turn of the throttle to get the revs up and then the clacking would start again like in the video.
Mountain Motorsports of Roswell GA took the bike in. They confirmed they could also hear the clacking. They did an initial oil change and told me the oil looked like it had some water in it and was low, but no metal at all. I was riding in the rain at Romney, but no water crossings or anything I could think of that would get water into the engine. They changed the oil and filter again and found nothing in the oil. Afterwards the bike was running and sounded fine. Oh and while they had the bike for 2 weeks, the battery got completely drained and wouldn't hold a charge. So I have a running bike that seemed to ride and run fine on the ride back from the dealership, but I'm a bit pissed about being down $545 for 2 oil changes, diagnostic fees, and a new battery in the 2 weeks they had the bike (even though the bike is under extended warranty until mid 2018).
I still don't know what caused the initial clacking, but I don't see how an oil change would have fixed it. This bike does consume a bit of oil, but the low oil level light was not on. Any thoughts or ideas from the group would be appreciated here. Thanks.
