Excuse my artistic disabilities, but here is one way of doing it using 2 relays. It does not take into account 190mech's point of a failed coil (RLY2) disabling the whole system. However you could add an emergency toggle switch to bypass the failed RLY2 coil. There is likely a simpler solution.  |

ERR,It seems we are talking about AC CDI(ground to kill) and DC CDI(open to kill),if thats so,then if an AC CDI system is installed on a DC CDI engine the best cure is install a proper switch and not a relay to do the work..Designing a relay system should be considered if what happens when the relay coil fails?Then the system should keep running..Thats the way we do it on aircraft anyway... The Zuma (and I guess other Yamahas) are ground to run (or open to kill) and AC CDI. The clones are AC CDI and ground to kill. I guess you could replace the kill circuit in the ign with a switch, but then the scoot can start and run without a key. The key would just allow power to lights and such. You could install a keyed switch, but no one really wants 2 keys to run. Finding an ignition that actually fits in place of a stock unit that has the proper kill switch function may not be easy. Thanks for the diagram Scott. I don't think it's so critical to have a fail-on kinda setup. Unless you're Luke Duke, the scoot shouldn't fall out of the sky if it shuts down. Prob easier to just carry a spare relay and make sure they aren't hard to get to. I was thinking there was something more simple. Kinda thought it was routine practice and someone that has done it would have chimed in already. |

I don’t recall anything special with my relay wiring. I always use my key to stop but I also have a domino switch for my kill. With the OEM it is reversed which is fine for kick starting but electric start if you still use it, it won’t work with the run switch in the off position (now run).
I also carry a spare relay with me.

Trials bikes have 2 killswitch types NC(closed) or NO(open) so if you have a NC kill you can use a single relay for simplicity. Put the kill on the trigger ground and boom you are set.
Piaggio typhoon uses a weird system that has a relay triggered by the key to energize stuff and iirc also controls the kill switch But I cant remember the specifics. However I have the service manual in one of my video descriptions.

"Get ready for insane rpms and upjetting a lot. mine took me from a 112 main to a 184 main jet. Only a good pipe now and 100 mph coming up"
That was a YT comment. I don't think I've gotta worry about 100MPH or upjetting 72 sizes, but have you guys had to do significant upjetting with your ignitions? I've heard some say they require jetting changes and I've seen either MVT or parts sites say to be careful with fueling and the new ignition. Normally my ignition changes are fine without much concern for the carb, aside from maybe trying to richen it up to avoid knock when advance is higher than it prob should be. I can imagine having to nearly drown it in fuel if the timing is crazy at part throttle, but it would seem smarter to back it down or just install that binary 0 or 1 throttle.
On a side note, I've got to say big props to the marketing departments out there. To listen to some of the comments, an ignition and exhaust will make this thing that's now allegedly a turd into a fire-breathing monster. I thought CDI salesmen for 4Ts were doing well, but this is next level stuff.

You better start the jetting about 200. Just to be on the safe side! It's going to smoke your T max.  |

Dont have a clue what the iggy curve is,but if its got a high initial then tapering,I'd say maybe richen up the midrange a bit and see how that is..

Hopefully I'm not way off here for a simple enough ground to run (N.C.) to ground to kill (N.O.) setup.  |

The ignition has been on the engine for a bit. Just been busy with editing.  Had a spacing issue with the pump drive. Took my washers out that are normally under the pump cover and it still looked like the pic below. Ended up putting 3mm worth of washers under each stud and hopefully it'll be alright now.  Just got done with wiring. Since I was full wave and the Trail Tech reg/rec also functioned as my headlight relay, I had to swap some stuff around and add a relay for the lights. Prob could run them from the ign switch with prob 50W worth of load total, but I feel better having a relay do the work. I thought about trying to use the charging or lighting signal from the stator as the switching signal for the relay, but thought that may be a bad idea in 2 ways. First, I don't know that the relay would like that input. Second, at least this way if the engine seizes at night, I still have lights.   Hopefully I can get some of that wiring tucked in a bit once the engine is in. Weatherpack connectors are huge, but I can add about 10-22AWG in the same connectors easily, which comes in handy. |

Very curious to see the video when you start dialing it in. Are you still trying to keep it a "streetable" tune or leaning more toward race?

Then engine is still on the bench so I'm not far off of being up to date with vids ATM. I want to be able to ride it. We'll just have to see if that happens. The most honest answer I can give you for now is that I'm just hoping it works and I don't kill it. "Will be nice to get advice how to do it without any tool if possible ..... on another Video for Beginner and 50cc stoke" I tried my damndest to make that a clear and detailed video, but missed the mark still I guess. I'm lost here. I told them if you are installing a $300 ignition, $15 in tools (cheap indicator and DIY holder) shouldn't be a deal breaker. Also told them you could install x degrees from TDC, but again tools would be required. If I'm missing something, lemme know. |

In the case of Youtube comments, I think we can assume that to be true. I'd like to find the YT video out there with the comments section that is actually sensible... I'm a YT addict and I've never seen that comments section. |
