top end rebuild between 6-700 to do it right.
need bore, pistons, gaskets at minimum.
I do reeds, pipe o rings, copper washers if you have a cool head, plugs, plug caps, anti freeze, and a few more odds and ends if you start to really get into it. like throttle cable, clutch cable, air filter, re pack the silencers. All the "excess" stuff is maintenance that is always over looked. I don't think ive ever gotten a bike in with good exhaust packing. ever.
