CT70H stator flywheel mystery

I like that combo... man I really hate to split the case on this thing, but maybe I should while I have it out of the bike.

I prolly should create a thread for the K1 to separate my projects as I await allenp42's coil prescription.

Is the 6V harness different than the 12V harness?

No and very few changes are needed. As of now, I'm at 1 change. I tend to err on the side of making the changes outside of the standard harness. You will need to make up a short adapter harness to get the wiring from the CDI kit to the existing stator plug, and add a few connections from the Rectifier/Regulator to supply the DC to the battery and everything else.

The only change that comes to mind is getting DC to the "yellow" wire, also know as the AC circuit. My thoughts are to break the connection at the stator plug and connect it to fused side of the 12v battery (red wire). That way your ignition switch will be able to turn off the lights.

After reading your last post and seeing the Trans Am, you can handle this with ease. This is a cakewalk compared to what you've already accomplished.

It's all about priorities & goals. I put out a lot of info, most of which I expect will not be used, so that folks have an idea of what's possible and be able make informed decisions. My suggestion is to begin by setting an overall goal...and your top 3 priorities. That will largely dictate the rest of the project.

On the one hand, I too would hate to completely teardown an engine that is running & shifting like new. On the other, if it's showing signs of fatigue (low compression, reduced power, not shifting as it should, smoking, etc) then it likely needs rebuilding anyway...and building anything with no more than a 52mm bore is not very different from doing a stock rebuild. It's just a few more parts to order.

The CT70, especially K1-later, can be turned into a reasonably competent 50-60mph machine with very few changes to the stock rolling chassis. Oil-tune the fork, swap-in some better shocks (suitable for adult weight) and the rest just needs to be in good operating condition. The stock brakes are fine up to ~55mph, Trailwing tires are J-rated...62mph.

That TA was 5 years of blood, sweat, and beers. I told my wife at one point "I'm half finished", she says "how do you know?" "Because there's nothing left to take off. It's a shell." :( If you have a place for off-topic builds on the forum I can share it sometime. It brought home some trophies.

I believe our perspectives are totally in alignment. I can start it on the first kick off TDC 99.9% of the time, and it literally runs and shifts like new with no smoke at all. It will pull 38 mph with me (165 lbs) on flat ground. I think I'll do the warmover like I discussed above, then if I come back to it I'll do the stroker/4-speed swap. There are a few more variables involved but I'll save those for the K1 thread. You guys have rehooked me.
