going under the knife! Got the parts in. All sealed up and waiting to cure so I can pressure test.

Got a squish of .69 before adding Honda bond. I’ll take it 😎

[gutiwarrior]

Pressure tested good! Time for MVT install. Still waiting on my timing tool.....errrr lol 

Look who’s in YouTube!

It's getting closer. 👍

Shortened the mvt wires and added the factory wiring. 








So my plans are to utilize the factory wires and locations of the stock components. The the mvt wired into the factory harness, you will get your charging and lights wire to the rectifier and the signal and ground will go to the factory cdi location. I’m going to unplug and de-pin the factory cdi and make a plug to plug into the new mvt cdi. 

The new cdi will get the signal wire, shared ground from the ignition and cdi, the coil wire, and the kill wire. 


A little problem I’m seeing on my bike is it’s grounded to run as the mvt needs ground to kill. Being a perfectionist and wanting to factory switch to display correctly, I’d like to fix this so it works as displayed. My thoughts are just to open the switch and swap the wires. I’m thinking this will work? If not I know you can do a relay of some sort to fix this.

I’m missing out by not hanging out in this folder. Looking good.

got the cdi wired in. Also made a block off plate that sits next to the mag cover. Didn’t have aluminum so steel and some bed liner it was 🤪

[gutiwarrior]

So I timed to .37btdc. Why? Idk. Lol oops. Needs to be .35 but I don’t think it will make a huge difference.

My next issue I noticed was although the kill switch was backwords (no big deal) the key did not kill the bike. Meaning with the bike running I could take the key out abs it would kill the bike. SO. I’m going to add a grounding relay.



85 switched positive from ignition. (Already a wire there from the old cdi)
86 grounded to frame
30 mvt ground
87 kill switch wire
87a grounded to frame


When the bike isn’t on, mvt will always be grounded. (30 to 87a).
When ignition is switched on, 87a will switch to the kill switch.
Kill switch will now control the mvt.


I’m pretty sure this will work. I’m no relay expert. In fact, never really got into them.
Any input is appreciated! Every bike is different so this is on my Yamaha vino.

I've already mentioned this stuff in PMs, but you can check against my relay info in the vid that I linked you to.

0.02mm (0.37-0.35) is roughly 0.2-0.3 degrees of ignition timing. Makes hardly any difference and likely many of us are off by that much just from viewing angle error when setting up.

time to wire!

nice relay install! Went as described as above. Key works as it should as well as kill switch.

Very nice work!

I’m getting around 13.5v with my led headlight through the mvt. Without battery I’m not getting much at all. Mvt I guess :/. The only thing I’m. Noticing is it doesn’t produce enough power to kick the relay on without a battery. Sucks as it works as it should but if my battery ever goes bad I need to u plug the relay. No big deal....I need to rethink the ignition wiring and see if I can pull ground from the ignition rather then switched power....

Cleaned up some stuff. Added a nkg spark cable. Nice addition to wrap up the mvt kit. Also added a quick disconnect to my fuel and got rid of the petcock. (A potential failing point) 







did some tuning as well! Currently with the new Athena evo kit I’m at a base line of 42 pilot 96 main. For now the bike is responsive and has a few rich points that I’ll take care of in the spring time when weather warms up. 

it purrs and jumps and yells! A few of you have seen it running and it’s going to give some people a run for it’s money. Hoping to break my 70mph run soon!
