Hello, I want to figure out where this rattle I have is coming from. It is a metal rattle that is random when climbing speed with half throttle. Its like a nut in a metal cup sound. Not consistent to anything and doesn't happen when parked and rev'ing the engine. my exhaust is tight and it doesn't have the stock headlight as some have said in searches I have done. I haven't replaced the chain on this one yet but it seems tight with about an 1" of play, so I am not thinking chain slap. If anyone has any ideas or has experienced this with theirs, any help would be appreciated.
