Awesome video! I respect that you are going the troubleshooting way instead of replacing everything. CDI broke probably because of hard mount to frame (vibrations), you should use rubber mount instead.
I'm sure people will find this useful. Can't be many videos of troubleshooting this kind of ignition out there. 👍 Onward to the next problem. At least it's making good viewing for us. 😁
After removing the kill switch from the circuit, I start at the coil then work back. If there is good voltage at the coil input but no spark, the coil is the problem. No voltage at the coil means the cdi box, stator, or wiring is at fault. Often though, its easier to just start off by plugging in another cdi box and try again(if you have a known good spare) since the cdi box seems to fail more often. Good video like always.

I saved your electrical diagram as it may be useful in the future. It’s probably available on your website/forum. I would find it unlikely for two problems to simultaneously appear causing a breakdown but I’m sure as time goes by the issues will be videoed.
Don't know the diameter off the top of my head, but that's all easy enough if you have calipers or just a tape really. You may be able to press them out with sockets and a nut and bolt. Use one socket to catch on the larger side and one to push on the smaller as the nut/bolt are tightened. Heat may help.
I'd whip the inlet manifold off and have a quick check that the reed valves are ok. A broken petal can lead to poor compression and is easier to check than taking the cylinder off. Its strange that you have cdi failure and a possible low compression at the same time.....good luck
I had really dumb issue as well, I was driving and it just bogged out, Tried starting it but had no spark, my cilinder had 2bar compression. Changed cylinder and spark just magicly appeared :D Btw it's a aprilia sr mk2 with minarelli lc engine, was runing stage 6 sport pro mk2 cylinder but when my small end bearing failed The cylinder was ruined :(
Nothing wrong with hopping up a four-stroke. Most builds can be good as long as you have reasonable expectations. Short of some serious engineering feats, the 50cc GY6 isn't going to be a wheelie monster capable of 80MPH like a high end 2T. It can be a good bike to ride though and still fun to work on. Just a 72cc kit makes them much more enjoyable to ride while still capable of being reliable with good gas mileage. The big bore is the big gain and then you're paying much more or spending much more time for any improvement.
I really enjoy your videos man. Still wondering why T2 won't start. I hope everything is ok with your piston and cylinder and there's no compression issues.
@@williamhaskellhaskell3162 Yeah, but IMO just take the cylinder off and check it. I don't like to question measurements and what I'm feeling so the extra time is worth it to be sure I can tell what's happening.
Hi what's up gy6 guru? Have you tried the adjustable AC c.d.I. units? Yellow ones Some have. One Phillips adjuster. One has 3 dip switches. ! They may be the answer. Bill
I have a purple adjustable Kitaco CDI for the GY6. It basically just changed when the ignition ramped up, but wouldn't do anything for total advance. That's one of the problems with these things is you don't know what you're getting and descriptions aren't always/often accurate.
Ok thank you. What about mounting a reluctor extention. On the fly wheel . Steel or flex magnets. Solder or cements? What would the max safe advance be? 5 deg? Any offset keys for the gy6? And is the increase acceleration worth it for a 2 h.p. gy6?
@@williamhaskellhaskell3162 I wouldn't mess with that. Not worth the risk of throwing the flywheel and engine out of balance or having a magnet fly off. There used to be offset keys. Not sure if they are around anymore. Not something I hear about lately. Ignition advance can give nice gains. You could potentially advance the ignition quite a bit, but I wouldn't blindly add a lot of advance. You'd be better off to try a little at a time if you had a way to adjust it.
You can still check timing with a light. This thing didn't like any fancy lights. I had to use a basic $15 timing light. I had 4 lights and that's the only one that worked. The timing light is picking up pulses on the plug wire, so it doesn't really care how you're getting spark for the most part.
I’m having the same issue on my 1999 Prebug Zuma. It wants to run, but will not fire, and I noticed that the vacuum fuel petcock is not opening fully. It also has plenty of compression seemingly, could the reeds be damaged or not sealing if there’s low vacuum?
Check the ignition coil. Check the output of the exciter coil. If a weak spark is causing problems, sometimes a tight plug gap, like 0.010"-0.015" will clear it up and help you verify that weak spark is the issue.
Well it hasn’t been started for a long time, so first thing I checked is spark and in normal lighting it’s invisible only in dark u can see it, so I assume it’s a weak spark.
I have a mineralli 2 stroke zuma and they key don’t turn the engine on or off just the lights. But when I start the bike without the lights on it revs but when I switch the lights on it will idle but not rev, kinda like it has a rev limiter. I’ve tried different stators, different cdi. Idk what’s up with it.. I posted a video on Instagram.
Odd. I would check to see if there's any continuity to any of the headlight wiring to any ignition parts or the kill switch circuit. Maybe some sort of short or interference. Possibly related to the switch. Not sure if that will get you anywhere, but maybe worth a look. I know at least some Yamaha stuff is ground to run. If that's the case here, the CDI is getting a ground on that circuit from somewhere.
In conclusion, are these MVT ignitions reliable? I have heard so many cdis being broken so not sure. I have ordered mvt dds for am6 but not sure is it mistake. And thanks alot for the stator measurements(ohms) because i really need them. Thanks and great video!
I wouldn't say I have enough data to make any conclusion on reliability. 190mech from the forums said that he has had a lot of reliability issues with a number of aftermarket ignitions in the two-stroke world since way back.

I actually just had someone ask me about specs for the red/black wire when revved up so I have an answer. Roughly 100V at 2000RPM and increases as revs increase. My max was a little over 14,000RPM and it reached 305V.

I will say that the time that it took for a CDI to fail is not good. I have heard from others that this is life with racing ignitions. I do like the MVT though. Being able to have a racing ignition and maintain my battery while using DC lighting has been nice. It's not on par with what the stock stator could do, but the stock ignition system couldn't make the engine run like this.
If it's not making spark, then you probably found why. Definitely go over your checking process to be sure all is good there, but 1V from the exciter is not sufficient for the ignition to work. You'll probably need a new stator.

Hi again, i have commented on your other video about MVT, you have explained here that Red/black wire along with green/yellow is energizing coil, would it be possible to machine a plate that mounts to the existing rotor with little magnet at the red line spot that will spin near the original pickup with the right gap and tell the CDI when to energize the ignition coil ? I own Aprilia RS 125 and i would like to get inner rotor ignition with lighting, 55 W is enough for LED lights but since MVT DD 12 Igniton does not have pickup, i would like to make a custom ignition point with that plate and basically just use lighting coil from the stator.
@@MrArni765 I don't think you'd need a pickup if you can use MVT's CDI. I'm not sure how it works, but I have to guess that it uses the signal from the exciter to trigger the spark. I have no obvious pickup, but I have spark timed where it should be, so it's getting that info somehow.

But the only thing I'm not sure how to do is where on the plate do i have to place the magnet to keep the correct ignition. I can set offset in the CDI program but I have no idea who to ask.
The water pump drive really shouldn't damage the ignition. My main concern there was if it would cause the nut to loosen and potentially change timing. It could stress the crank and potentially cause clearances to change if it did. I don't think that is happening. I will verify the timing mark alignment though.
Mine sparks first time when I crank it after that it does nothing, sometimes it will work as normal, but it will eventually come back to getting spark first when I crank it
That's an unusual one. If it were heating up and then stopping spark, then it would likely be the stator failing when hot. If it's just turning over the engine and it doesn't spark after the first tries to start it, then I'm not too sure.

@@deathvader58 The video was intended to give some ignition info. The bike had other issues (shown in the next vid in the series).
@@49ccscoot Fine job! Very helpful. I have the same issue with a kinetic TFR. Have spark, new carb... Nothing, not even a pop on starting fluid. I did have to free the piston loose. Likely have a stuck ring too. But does have compression and should fire, especially on starting fluid. New CDI on the way, we'll see.
@@chrisricks6736 Good luck with it.
And since then how many cdi’s have you bought. Because I bought mvt ignition and want to know if they are reliable.
None so far.
@@49ccscoot so they are reliable
@@2strokemf I have hear that they are not the most reliable... but I'm out there riding on the street. I think with race oriented stuff like most people would use them on, they're not necessarily your biggest concern.
@@49ccscoot I am also going to use them on the street.
@@2strokemf It's not cheap, but if it's a big concern there's always the option to carry a spare CDI.
Hi will non resistor plugs and or caps hurt the c.d.I on my gy6? Bill
They should be fine. I've never noticed any gains from non-resistor stuff though, so I use resistor plugs and caps on all of my scoots.
