Hi Scott,
Murphy's Law; Rule 638A: "All Motorcycles Will Fall Over, Usually At The Worst Possible Moment!"
True. I do a lot of touring with a group of long time friends and helping some one upright their overloaded, friggen HEAVY dresser is a routine event. Some good natured ribbing, a quick visual inspection, and we are on our way again.
I wholeheartedly agree with the other members, from your description of the dent, if it's not leaking now, it's not going to leak. The tank's sheetmetal is heavy gauge and can take a fair amount of abuse. My advise is to do an up close inspection of that side of the bike and double check for any other damage, load her up on the trailer, and go enjoy the ride.Trust me, you will regret it if you don't. Me and the above mentioned group spent a week in that area last month and had a great time. The Blue Ridge Parkway, Smoky MTS., Appalachians, will completely clear your head, and if you are still thinking about the dent, a little trip on Rt 129 in Deal's Gap will solve that!!
Do your trip, enjoy this still great country and deal with repairs when you get back.
Best Wishes & Have a safe ride.
Tom P.
