I changed it to a 56 tooth & that works great!! 48 was a little high & the engine was losing power before hitting top speed. I also got a hub adapter to hold the sprocket on from Pirate Cycles. Justin ships fast. only took 2 days to get it.Hi Jay, seems to me that when I shipped your Manual, it had a 48 rear, with a 9 tooth front? I know that ratio does not work well on Q-Maqtic, you changed out the rear sprocket I guess?
