I recently found that my swing arm at the bearing end damaged heavily by my chain. This is a first for me. In 47 years of riding I've never had this happen before. The chain had eaten through the top slider and into the swing arm itself and eventually into bearing race. This happened with a relatively new and good chain that had been adjusted (1" of slack top and bottom) before a two hundred mile ride. The damage occurred during that ride. The slider and swing arm were fine prior to the ride. The chain was also lubed. So, I know that bikes like the WR250R and CRF's require a tighter than spec chain to keep this from happening. Will I need to do something like that? Tighter than specs? Lets NOT get into chain quality and types or to lube or not to lube. Please just focus on chain tension please, let me know your thoughts, and what you think is the right way to do it. Do you tighten yours more? Less? and why?
