Hello. I’m as new as they come to this forum but have been a Polaris fan for years, owning snowmobiles and a couple different atv’s. My most recent purchase is a 2015 sunset red 570 sp. I gotta tell ya, I love this bike. The ride is increddible and I love the power steering. The engine braking is a bit much at low speeds but I’m getting used to it. The only issue I have is a bang type noise when starting off from a start, either forward or reverse. I first heard the noise when loading my new bike at the dealer. I just wrote it off as clutch noise but I think it’s getting worst. I spoke to the dealer and he tells me it is normal drive chain noise that will go away or greatly diminish after break-in. He says that the chain in the case is on an auto tensioner and when the chain stretches through normal break-in it will eventually allow the auto tensioner to move to the next notch and take up the slack. Anyone ever heard of this? The noise is quite loud on heavy take off and almost gone on slow take off. I can make it happen on demand. I do notice that sometimes when it bangs going forward, I have to drive in reverse before it will ban again. I think I also hear it on decell at times as well. It is quite loud and Im afraid something is going to break. The bike has just under 100 miles. Your thoughts and experiences are greatly appreciated.
