Went to Orlando from Tyler, TX (1056mi) on a ~70,000mi GS500E w/drag bars and a Vance and Hines exhaust. That SUCKED. Top speed was about 65 because any faster and it would just shut down after 5 minutes. Swore I would never ride that thing that far again..... Four months later I headed back on that same old POS Suzuki. New cylinder head, but that was the only change. I know four months is a bit longer than you were asking for, but it felt like a week to me, and is so distant a memory now that it seems like it was all a dream.....
