I Run a stock 850 so far, so what changes are you seeing for tracks speed, we seen 50 mph track speed in 4 feet of fresh this week, pulling 8000 rpm now with 4 grams a arm added to pivot bolt on pdrive.. 8 percent Breakin left as well?? Would think you would of added a lot more weight than that?

My belt on the 174 is right up at the top less than 1/2 inch from the primary, it will need a gearing change soon, thinking you might have down this already, with that BB?

Neet to see some helmet cam vids of it pulling a few hills.. How is skid handling extra power, because it needed a few changes in stock power already..
