Electronic Ignition for xs650

Yes, those are the ones. As you can see, they can be found dirt cheap. I'd be buying those if I didn't have a couple extra already. For me, the single coil thing is about cost. You only need to buy one, not two like for the original points set-up (or this Tytronic).
 
I gotta little ways to go too.
Gary are those forks 38mm FZ?

Just found your build thread ,looking good. What are those forks fetching? what mm size are they?

I think they ARE rather fetching LOL, 41mm. Freeing those was loong story. No title, "under a tarp in the back yard" bike, partial trade for a shotgun. Fixed the issues that put it under a tarp, rode it a few hundred miles, then sold it to a guy that ripped it apart to put the engine in a quad, he brought me back the front end!
 
ok I going to make a shorter video tomarrow, Im about to pull my hair out trying to use you tube with my internet conection, I guees I wont be starting a you tube channel lol,

there are two of the updated versions with the onboard led timing lights left at the 75 dollar price
please pm me if interested
 
Yeah, and I think it was easier to start in 2nd. But here's a good time to ask. Has anyone ever towed a buddy's bike home with theirs?

these?
me and my buddy are lovin' those Honda MP08 coils we installed. I'd love to be able to use one with a cheap home brew ignition.

Yeah those. Honda used them on over 70 models. Great reputation. The two generations of Honda coils before them did not have such a good reputation, not lousy, but not good. I have a big box of the previous Honda coils that are marked with felt markers "bad". The MP08 is a 3ohm coil that works best with TCI ignitions. They can be used with points but only with a ballast resistor, or the points will fry. So, 3ohms plus the ohms of the resistor equals the ohm spec of the stock coil for points.

Hah, turns out I'd been using MP08 coils without knowing it. First set I got was off a wrecked CBR1000 which wasn't all that old at the time, and they've gone on for many miles totally faultlessy, being hooked up firstly to the 'Zuk electronic igniter, and when that died (as they do, eventually) they've spent the time since being connected to a Piranha system. They've probably done at least 100,000 miles.
What really caught my attention at the time was the ability to replace the HT leads, which the 'Zuk coils don't. For the past year they've been feeding some 8mm silicone leads and resistor plugs. The 8mm leads were a bit of a squeeze though, needing pared down a fraction.
 
Yeah, 2 NGK caps, a few feet of metal core 7mm silicone wire, one MP08 coil, about $20 total. Compare that to an Accel or Dynatek kit etc.

Curious, the MP08 coil, its a two wire single coils, fires both plugs simultaneously?

When I first built my bike back in late 70's I used auto coils with ballast resistors, the hot set up for the day.
Later owner ditched the "huge f'n auto coils" in favor of a couple molded yellow ones, kept the ballasts.

This new pointless rig will work with the single dual fire coil and I can ditch the ballasts along with condenser's?
 
Unfortunately no, the Tytronic ignition being discussed here is designed to retain and work with the original 2 coil set-up. We're just all wishing it was set up for a single coil is all. That Honda coil is stone ax reliable, dirt cheap, and you would only need one. The original coils aren't very powerful and if you wanted to upgrade to better aftermarket ones, you'd need two and it would be pretty expensive. As far as aftermarket coils go, there isn't much difference in price between one coil with a single output or one with a dual output.

If you mean the Tytronic ignition, no, the Tytronic manufacturers specify to use two stock coils or two single output coils with more than 3ohm primary. Confusing whether that is 3ohm or more (3ohm inclusive?).

I am going to use one dual output coil with the Tytronic to SEE if it works, it may not work or something could be damaged. Communication is hard with the manufacturer but the ignition looks promising.

I hope they come out with a E- advance.
if you go back a ways in this thread I was discussing making our own E advancer for use with the tytronic ignitions,
I got some mixed responces on the subject..
I have one tyronics electronic ignition left at 75.00 and 7.65 shipping
once that one is in someones hands we will have a total of 7 members trying these out, I have installed on a bike I rode a few days ago and was very happy with it,

so again Im calling on the pixie spark wranglers out there, you guys know who you are, I have one guy here in Portland but I think he is kinda a novice, there isn't that much to a E advancer, althou What I want to see is an e advancer that we can select our advance curve for things like gasoline quality, or higher compression, or whatever may require a costomised curve, AGAIN Im not trying to produce something to put anyone out of bussniess and since there isn't already one out there that does that customized curve, ALSO Im talking about doing this as a collaboration, and OPEN SOURSE , that means the plans are free to see and change if you think you can improve upon it.. I might even contact some guys on an electronics forum, if I knew what I was looking for lol
anyways WE can have it , if we stop waiting for someone else to make it and we do it ourselfs
 
An improved spark advance circuit for use in an electronic ignition system for an internal combustion engine in which pulses generated in a pickup synchronized with the engine crankshaft are fed to a circuit for generating a voltage proportional to the desired advance and to a phase locked loop which is adapted to generate, at its output, a ramp synchronized with the input pulses, with the ramp output and proportional voltage supplied to a comparator, the output of which generates firing pulses which are advanced as a function of engine operation for use in the electronic ignition system.
