lots of rants and no help to the OP.! snorex I would try some clutch work { helix, springs, weights} try carls or indy dan both are knowledgeable and happy to help meet your needs!! you would be surprised what it will do for you. and for the gear down well that's your pref. I love the powder and next to never go in a strait line so I have no need to be geared over 85 or 90 and I like to be geared down {hade a 700 geared at 78 mph and loved it} truth is when im on the trails I rarely crack 60mph most of the time im going 35-50mph any way if you aren't willing to do the 660 kit try it.
good luck on your venture
