Hi guys I am new to the form and looking for some help. Recently bought a 2013 outlander 650 xmr with around 1400 miles. Ok, so now to the problem, only when I am in high gear the quad makes an extremely loud whirring/ squealing noise. It does not make it when in low. It also only makes the noise while I am accelerating. If I let off the gas it goes away. I took the tranny apart and found black goopy grease in it, replaced all bearings and seals as well as the pinion bearing and the high gear itself. After going through all of this the noise is still the same. Considering taking it to the dealer at this point but they want to charge $90 to even look at it. Any help is greatly appreciated. I will try to upload a video soon
Thanks again
