Maintenance-wise the shee is fine, ive replaces chain recently, sprocket, suspension, brakes all seem to be performing fine. I'd say I'm somewhat mechanically savvy and maintenance hasnt been a problem. When i stated parts where on their deathbed, i meant in terms of aesthetics. I ride in the desert and the occasional dune so ive considered cutting the fenders. i have a k&n filter already, but haven't wanted to remove box yet cuz i want to get pipes before i rejet. I dont understand what you mean by flywheel puller and small rat tail file. Can you leave some instructions on how to do some of this stuff please?
