I wanted to ask those who have streetable YZ's, what's the longest seat time on the street in any one sitting anybody has? Reason I'm asking is that I'm definitely going to end up in situations where I might have to either ride 15-20 miles at highway speeds to or from some riding areas or end up using the trailer. Since I'd rather ride I was concerned with stuff like cooling problems or anything anyone may have to suggest might go wrong that I could pre-plan for. I'm on the up side of reassembly and am looking for problems to solve before they happen. I've already read about the gearing and tire choice. Anything else?
