I just bought my (new) Bike and the guy that had it before me installed frame sliders. He told me that the one on the right had "fallen off". Now I know that that is an engine mount, and this can crack the frame. I went to local dealership, and he told me to go to the hardware store and find one that fits. This may be ok for a lawn mower, but not my R1! it only has 2300 miles and the sliders were installed between 1500-2000 miles. I need this Bolt! Any and all suggestions are welcome.
