I was asked about what I did to the engine: I’ve pulled the oil pump and rebuilt it along with new seals o-ring and springs. The inside of the oil pump looked like a Jewell box it was all new and shiny before I rebuilt it. I have had the valve cover off the cam was perfect and adjusted the valves. I don’t think a shop could yank the engine inspect the top-end set the valves for less than a couple grand. I went ahead and put in new points plugs along with a couple condenser’s, set a new clutch in-place and adjusted it. I replace every nut and bolt on the engine. Put in a new pressure oil sensor and seal along with a new cable and boot. I installed a new neutral sensor and cable. Then I add a new stator harness. I replace all shaft seals with new Japanese seals, gear box, shift lever, kick start and clutch seal. Tossed in a new set of oil lines and what would the total bill be? That’s just the engine. Then I re-chromed the Kick start lever, the brake lever, the stater motor cover the clutch cover and replaced the points cover with a factory new cover. Had the valve cover, stator cover, gear box cover, sprocket cover and clutch covers all buffed and polished.
