I just picked up a new 2017 m8000 153 sno Pro. Haven’t been out yet but thinking im going next weekend. The bars seem to be really far back and low for me. I am 6 3 and always did a 3 inch riser on my old m series and loved it. I want to do something like that but I heard there is a forward post block not sure what that is. Also how tall of a riser can you go before having to change cables. I really don’t want to change lines or cables. I guess what I really need to know is what’s the most I can go up and stay stock wires and line? What is the forward block? Thanks
