    I didn't say H style. It's from a SL70 or another model 4 speed that has the condenser elsewhere on the bike. BUT you can wire a condenser in that stator and it will be like a H would have. The stator has the indent for the condenser, it's just not wired in. A neutral wire goes from the main harness plug to the stator plug end to the neutral switch. It's not supposed to be wired IN the stator. No neutral switch bikes are 3 wires and bikes with the switch are 4 wire plugs.

    Notice the green neutral wire pointing up that is part of the mess of wires? Thaink of that as the 4 wire plug. That goes right to the neutral switch. It's not wired in the stator.

    allenp is the stator rebuilder here that I would trust to test/customize/rebuild your stator for your needs, He has done several for me already.

    Hi Beretta . I would double check the amount of crank with have sticking out.

    Honestly, I am struggling to accept you have 4 speed crank and what appears to be a 3 sp flywheel. Based on your first pic, it appears the flywheel snugged right up. If this turns out to the case, I want your old flywheel -:)

    Take a look at these pics and you can clearly see both ends on the ruler.

    Just to add to OLDCT's post, CDI sure is nice, but understand if you don't go that route if you're trying to get back close to how the bike was born.

    I was wondering why the 3 speed flywheel is hugging the stator also, just didn't word it in text. It should have noticeable gap and not line up with the coils, that screams I a wrong for the bike.. This sure is a head scratcher bike, no doubt.

    The light bulb just went off, the h stator plate on a 3 spd crank is giving a different measurement VS my reading of a 3 speed stator plate with a 3 speed crank.!!! Thanks, allen!

    All that bike needs is to put on a 3 speed stator plate, and swap those coils to it and add a condenser. The neutral wire may already be still in the harness. Look at the plug. Then add the short wire to the stator side. Very easy to do.

    Even easier would be buy the cdi conversion 4 wire for a 3 speed Hitachi flywheel. Never mess with points/condensers again and is totally hidden, plug and play. This seller is very thorough and wants you to send pics. Just don't send a pic of that stator you have, it will mess him up. Lol. Say it's a 4 wire and show the 3 speed flywheel and the 4 wire stator plug.

    Just Like Pic 2 !
    Yes there are other ways to get it run including a new CDI --I just want it Pure Stock as it was built in Japan-- Just Me ! I guess - All of my Bikes are original as they were produced at the Factory, I don't paint them- I repair them to original condition.

    How often are you guy's actually messing with your points??? I never touched my 50's points until the early 90's when I did the top end. Bought my '74 TL as a non runner in '95. Never have touched the points.Changed the CT's when I rebuilt the H motor in 05. My MR bought in 05, never touched. Now my 48 Ford 8n tractor different story- every year at first startup need to clean them. Only difference I can figure out is that the Hondas are all oem. Ford is what ever I can get.

    I don't have any K0 or K1 stators at the moment and just took a look on e-bay - ouch. A bit pricey ones is all I saw. However, I do have a K0 stator plate and some good used coils. If you're not in hurry, I can put one together for you within a week or so? Or I can send you the stator plate and new condenser and you can removed the old parts from the stator you have. However just a FYI, an SL70 lighting coil is an odd duck - not the same as a XL70, CT70H, K0, ST70, or anything else for that matter. You may be better off to replace that puppy as well if you're going back to the factor DNA.
