today i installed a Battery tender pigtail on my 2011 rts, what i found is disturbing!!! the nut and bolt that holds the ground to the frame was a jury rig at best. there is a threaded boss on the frame but the thread size accommodates a bolt larger than the holes in the ground lugs, so they used a nut and bolt a couple of sizes smaller, a spacer, and placed it through the frame. so when i finally got the bolt out the nut fell out to never never land. the proper way to attach the ground would be to put the proper lugs on the ground straps and the right size bolt. i have seen other posts from riders that said they could not tighten the ground. may be this is not from the factory, but the size of the ground lugs would say it was.
