Detailed MVT Digital Direct Ignition Installation How-To : TPR 86cc Build : Part 21

[@elizabethmcheffey8699]

Thank you this will be the definitive MVT installation how to guide on you tube or web excited to see pt 2 thank you for dumbing it down!

[@pitobread]

Great video. If you want an absolute TDC measurement I reccomend using the piston stop method and a degree wheel. Rotate till you hit the stop, roll it the other way hit the stop and split the difference in half. The dwell at TDC means you can easily have a few degrees of dead spot. All that said in my own video I use this method as well because I am lazy.

[@49ccscoot]

What good would that do when the spec is in mm? If it were in degrees from TDC, I get it. You'd want to know true TDC. It will be the same distance in mm from TDC if you're anywhere in that range where the piston dwells for a few degrees. It actually surprised me at first when I got into this and realized the margin for error. Just seems like they'd let you setup a degree wheel and tell you it's x degrees BTDC. Could run a calculator, but apparently they (and as I understand it) most other racing iggy manufacturers just tell you distance specs.

[@pitobread]

You could I guess in theory do the piston stop method, fix the crank, exchange the piston stop for a dial gauge, zero it and then set your mm.. I'm already tired writing that. Because the dwell still relates to crank degrees. So your tdc is not the "true" tdc. But for all intent it's probably close enough.

[@49ccscoot]

@@pitobread I was actually making another video in the garage just hours ago about finding true TDC with a dial indicator and checking that against a piston stop and just zeroing a dial indicator. What I can tell you from that, is that it's still the same distance from TDC with it zeroed with the indicator or using true TDC, because one is a measurement of distance from the top of the piston's travel and the other is the amount of degrees of crankshaft rotation from true TDC.

[@pitobread]

@@49ccscoot Like i said it's barely worth the effort, but it can be in some cases! It's going to depend on your rod stroke ratio. short stroke long rod motors could add up! Here is a neat calculator that can help with numbers to show exactly what I am describing. www.torqsoft.net/piston-position.html If you put in 44mm stroke, 80 mm rod, .35 angle and set it on piston position. Calculate it then change your rod length to 105. One has your piston juuuuust starting to move and the other one hasn't started yet. You can also use this to tell you exactly how much dwell you have at TDC. Remember it will be x2 whatever the angle is. This is what I mean by true TDC.. in the end it doesn't really matter, if you math it out and round it relates to about a degree of error. Not enough to worry about. Just figured I would mention it before someone tells you your piston is in backwards. ;)

[@gondolaservicepeschieradel4115]

Hy i'm not in agree, for your 86cc with 44mm crankshaft it's needed by Top performance schedule 20° BTDC. With 0,35mm of BTDC you have 1,43°. You can calculate with this formula X°= (180xYm)/ms . Where "Ym" will be the BTDC and "ms" will be motor stroke. For example, with 44 motor stroke, you'll need X°=(180x4.88)/44 X°=(578.4)/44 X°=19.96°. BTDC 1,43° it's not too much anticipate, and the motor can't ignite the gas properly.

[@49ccscoot]

TBH, the TPR spec of 20 degrees has never made total sense to me. They don't specify where. Locked out at 20 degrees isn't going to do the best. 20 degrees of base timing could mean all sorts of things with different CDIs. With the MVT as setup here, it has over 40 degrees of timing at low RPM and reaches 20 degrees around 11,000RPM. It continues to pull timing as RPM increases. kzbin.info/www/bejne/gKbImXp9mMh9nq8

[@gondolaservicepeschieradel4115]

@@49ccscoot I investigate, and i think on the MVT the line is not the pick up, but the charge to produce electricity, i translate the recommend on the manual of MVT and it'is: "before top dead center if the cylinder is 50cc, if the cylinder is greater than 50cc it must be set at 0.35mm before the top dead center, likewise the lighting must not exceed 55w" , i think to never go up 55w they say for 50cc motor keep it at 0mm, for upper motor keep it at 0,35mm, after the timing of the CDI will do the correct timing of 16° or 20° for the TPR 86cc engine. So my excuse for the precedent message ;)

Hi dude I hope you read this and get back to me 👍🏻 I really need to know if the taper on the Yamaha crankshaft is the same as the Chinese crankshaft?? I need to know this as I own a CPI mvt ignition but my new cylinder requires a 85mm rod which I can only find for the Yamaha. I hope and pray that the taper is the same or I may have to buy another mvt ignition 😒

[@49ccscoot]

The taper on the typical Yamaha crank is the same as some clone cranks. The clones have large and small taper versions. Large taper is very common on the CPI 1E40QMB. It's supposed to be pre 2003-2004 they would be small taper and post would be large. If you have the 12mm crank pin and larger splined section on the CVT side, then it's pretty safe to assume you have large taper.

@@49ccscoot is there anyway to do this? I mean I have large taper but i want inner rotor...

[@49ccscoot]

@@tamer27antepli It's not as simple as drilling a hole. You would need someone to bore it to the proper taper for your crank. Unless you can do it or have a friend with a lathe that owes you a favor, it would at least make sense to see if you can get a price on the rotor for the 16mm crank and perhaps make sure they can interchange (no difference in the stator).

[@49ccscoot]

If it's a DD06 with the included CDI, then it should be 0.40mm BTDC for the initial setting. Double check that. If it's not the DD06, check the specs for whatever model number you have. If you use an E-PROM CDI with the Digital Direct then they use different specs too. If it kind of kicks back at you, it's probably got a lot of advance... but that seems to be normal with mine.

I've had a failure where I think a bearing went first and it bent the crank and broke the ramp plate on the variator. At high RPM, a lot is possible. Regardless, high rev setups are much better with inner rotor ignitions. Aside from the difference in mass, they generally have a much better timing curve than standard CDIs or a lot of aftermarket CDIs.

[@49ccscoot]

This seems to be pretty common with the E-Prom from MVT. At least for Minarelli, they want 2.9mm BTDC, as opposed to their standard CDI that's around 0.35-0.45mm BTDC usually. If you've backed the timing off to half of what it was, I would first suggest double checking everything to be sure you haven't got anything off in the process. Even at 2.9mm with the E-Prom, most report intermittent reverse starting. For example, a friend said about once every 5 starts it may start backwards. Seems to be right on the edge if it's setup to spec.

After setting piston to the stroke timing, do i have to reset the timing marks again after advancing or retard the stator?

[@49ccscoot]

When the piston is placed at the desired distance from TDC, the marks should be made to align so you know it's set right. Recheck to be sure nothing moved after the rotor is installed. After that, you can move the slotted stator to change timing as you desire. If you want to put it back to the standard setting, then align the marks again by rotating the stator to it's original position. The marks won't align at the standard setting after you rotate the stator.

Hi there... Can it be that you forget you're woodruff key? I didn't see you set it back when you install the rotor. Or am I wrong?! Nice video! Greeting Mike

This uses no woodruff key. The rotor isn't machined for it. That's why you have to go through the timing procedure.

I really can’t advise on this since I never touched a gtx and they are not really minarelli engines. Chinese knock offs are so mix match of parts that I don’t know which part would fit and which won’t. I know it’s not the answer you want to hear but honestly in my opinion it’s not worth the time. For me to get into detail of the 101 variables on jog/minarelli engines will be too confusing and since it’s not something I work on I wouldn’t know where to start. My suggestion to all those that message me Chinese clone motors is to leave it stock of it runs. Any modification and you are opening a can of worms money pit. You are more then welcome to try but I can’t really be of help. Sorry Mahalo for the acknowledgement of me knowing minarellis but I have no clue when it comes to the qmb line of motors “Okay bro, I messaged the local expert on minarelli engines and the above was his answer. “

I don't see where they're al that different from the Yamaha Minarelli horizontals, like the Zuma. Yes, there are multiple differences, but most of the engine and CVT stuff generally fits. The Chinese engines do have different sizes of wrist pins, flywheel tapers, and variator splines. When you get to the gearbox, that's different than many Yamahas and there are multiple versions.

Hi, did you have problems that these ignitions get no spark or suddenly start missing and not reving?

[@49ccscoot]

I lost spark once (MVT troubleshooting video). CDI was bad. Since then, no issues. Using an MVT DD on my RC1 as well now.
