Just wanted to drop a line and let John know his kit works great and to thank him for working with me to get it dialed in with clutching and gearing. It was also spot on at elevation and sea level I really like the feel of the big bore. For everyone thinking of the big bore I would compare it to about a 30 hp shot of nitrous you sure ain't going to climb out the top of a nasty shoot but you will beat the tar out of the stockers don't care what flavor, and you don't have to mess with race gas or find or carry nos. Just a really fun ride. Thanks Bill R.

I just spent the day tweaking my SHR860 a little more, and because of that, I'm going to have to suck the limiter strap up so I can get OFF of the front bumper during climbs and move to the more natural position of standing BEHIND the bars
