Ok .......It IS official. Over the last day or 2 I pulled my speedo off of my Schinn 3spd and modified it a little to fit my 4HUN. I was going slightly up hill and the speedo indicated 44mph. (It had already gone around 2 times and nearly 3 when it read 44mph!) That thing is just like new, so I know that it is exactly right. I would love to try it DOWNHILL!
