if you were wondering the price of a rebuild, i spent 250 in parts, then 30 for labor, you could do a rebuild based on parts any where from 150 to 200, i just wanted to do all new oem parts in the top nd, i bought: valve seals, rocker arms, new valves, every gasket/o ring in the topend, rings, allnew topend bolts/washers/and then i had the cylinder honed, a broken exhaust stud removed valves seated and rocker arms adjusted all ports cleaned out, the only thing i have to do now is cut my fenders, setup an oil cooler put my new rear bearings in, then depending on funds 14/40 gearing withh oring chain
