2 Yrs ago I rode an APEX at the Yami demo. I was impressed and I'm ready to change brands now. I know that with the extra weight I will want a little something extra to get me where I usually ride and back. Most of my riding is boondocking. I've been riding a Polaris 800RMK that really runs well but I'm afraid that I'd need something up my sleeve with the extra weight of the Yamaha. I'm not into point and shoot hillclimbing so I don't think that boosted is the answer. Is NOS a good fit and how well does it work? I haven't heard much about it on the Apex's. How big of a tank should I consider? How hard or easy is it to tune? Is any box/brand better than the other? Any advise, experiences or opinions are greatly appreciated. Thanks, Curt
