I am curious what those of you that have owned the 708 and the "new" 686 think of a comparison of the 2. I was wondering how power compares. Also curious if they fixed the leaky air filters. I am eventually wanting to get a new grizzly or kodiak 700 and am wondering if the new machine is much of an improvement over my old 2017. I was frustrated with the leaky air filter situation and the oil burning issues (I had mine rebuilt under warranty and got an aftermarket air filter and it wasn't fixed). Thanks for any thoughts you all might have.
