      LOL , ya, mine is a Canadian Tire special, had it for a while, leaves puddles of hydraulic fluid on the ground She works fine mostly, unless you want it to hold something up for longer than 15 minutes
      I was able to actually find NGK D8EA non resistor plugs there today
      The bike shop said they couldnt get them

          Got it running tonight
          Sounds good, but it was late so I only ran it for a minute or two.
          Strange thing, when I put oil in it, I pulled the plugs and flipped it over for a while to maybe get oil circulating, oil light never went off, didnt want to drain the battery, so I threw the plugs in and fired it up, and the oil light went out, but now it wont turn on
          I pulled the oil gallery plug next to the ignitor cover and turned it over and oil came flying out, so it has oil pressure. Do these oil pressure switches sometimes get stuck? Maybe that rotten red crap they used got in there or something, or maybe just 24 years of sitting

            The oil pressure sensor is just a metal plunger with a spring pushing on it. When the engine is off the plunger caps off the main oil feed port thus completing an electrical ground path. When the oil pressure pushed the plunger out of the way the ground circuit is interupted and the light goes off. You can test the circuit by grounding the electrical wire going to the sensor - it it lights up the bulb, the circuit is working and something must be holding the sensor off the seat.

              I had a problem with mine on the like new ED motor I installed recently. It had not been run for awhile. I had to clean the spot on the cases where the contact is made with the sensor plunger with 200 grit sandpaper. A Ed said just take the wire that goes on the sensor and ground it to something. The light should come on.

                  Once you iron out the little "bugs" it will be a screamer!

                    I guess my first thing will be rebuilding the clutch hub

                        Did you check the clutch hub nut?

                          Get a gorilla nut, and a reinforced basket if you can.

                              I pulled the clutch right out, to inspect the parts and the plates, (and so I could see if the crank was welded) I noticed that the cush springs were loose. Strange, but the springs on that hub all had washers with the springs, factory like. The heavy ones were loose, the others were tight.
                              The noise isnt as bad now that I have the jetting closer, but still has to be addressed. When I can I will get the clutch upgrade parts from APE and have it welded locally. I cant really afford the complete Gorilla assembly, too pricey (more than what I paid for the parts bike).
                              I put in #130 mikuni mains as opposed to the #138 dj mains. I had to set the needle to the next from richest position for it to run properly. I am also going to have to go with 47.5 pilots as I have the mixture screws at 3 1/2 turns and it still pops on decel. I think I am going to put in 137.5 mains when I have the bowls off to replace the pilots, to be on the safe side.
                              EDIT: The gorilla upgrade is a not bad price, I was thinking of the billet one. I'd rather get the kit anyway instead of shipping my hub all the way down to them.

                                My buddy races for APE and I head over there all the time. I can pick one up for you if you'd like.
                                138 DJ and 130 Mikuni are about the same jet. Remember the needle and the main affect each other so dial in the main first and then the needle.
                                I'm running a 137.5 on my ED motor with pods and a pipe and it's perfect. The needle is 3 notches from the bottom.
