69 Years old, Long Distant motorcycle rider - Pump driven-Present pump 508 in the process of up-grading now to the new pump and monitoring system. I have been pumping lots of U-100 so I changed to U-500 last week. So far so good, I have been using approx 16 units of the U-500 / day compared to 200 units of U-100. It looks like I will have better control with the U-500.
I love photography, History, Mexico and Video -
