The idler for sure caused it. I saw photos. Mark knows what he's talking about and BRP covered all the damage.
Mine seemed okay but I decided to upgrade to Docs as it is better quality.
WackyDan's was chirping, a sure sign a bearing going. Bearing fail, with the bouncing this one does it's no shock they fail within 10,000 miles.
It's not that difficult to look at something and tell if it's cheaply made or not. The Smooth Spyder ones are very beefy and well made. Docs seems well made as well. The BRP and Airwing one.... not so much.
Not sure why you're being so defense of this $50 idler. I liked it too when it came out and thought it was great, but opinions change based on the experience you have and what you see happen to others. You might get 50,000 miles from your idler with no problems or it might fail tomorrow. As much as I ride I don't care to take the chance and have it tear up a belt like it did to Mark.
Don't do an upgrade if you don't want, but I would keep an eye and ear on it.
I'm not being defensive of my BRP Idler. I'm searching for the best out there to enhance my ride. I beat up BajaRon pretty bad on his sway bar and I lost, he was right. I'm doing the same now to both those adding their own 2nd bearing or Docs. I'm a perfectionist, I'm trying to understand why two vs one bearing is better....or worse. Does two bearings make the belt vibrate less and last longer? If that was the case I would buy Docs when I'm up at SpyderQuest....if he'll talk to me, lol
