No, I probably don't. I was thinking about it because I just about ran out of fuel yesterday. I leaned the bike over, sloshed some around and got it restarted and made it to a station. It seemed like there was gas in the tank that wasn't making it to the petcock, and a reserve petcock seemed like a highly desirable thing to have at that moment.
You are right, it would be a lot of work for not a lot of gain. I was just wondering if any of the experienced hands here had tried it.
Thanks.
Bill
