do it on the right side. i hit a patch of gravel in a right turn last night (we get a couple of inches of snow here, and there's gravel on the road until april...), and laid my bike down pretty hard. i got up, rubbing my right hip, and ran over to hit the kill switch. oil on the ground scared me (fell out the breather tube?), but after returning the bike to it's upright position, i couldn't find anything wrong with it. i walked around it, confused, and then fired it up and rode the two more blocks home...with the rear brake pedal a couple of inches too high.
this morning upon better inspection, it appears i got away with a barely scraped right handle, scuffed up outside header pipe, lightly scraped brake pedal, and...a bent brake stop (the tab on the frame), from when the brake pedal took almost all of the impact. you have to look hard to notice any damage.
i've got a pretty decent hipper (thanks to the rivets on my jeans and my leather jacket, no lost skin) and i'll have to heat and bend that brake stay back in, but it could have been much worse. .the left side doesn't have much to protect the serious stuff...
