Hi all, just trying to work out how to fit the VMC stator. There's no instructions so it's difficult to say which way is up. In this picture I've placed it so the wiring exits close by, because it seems to make sense - and Henri had mentioned 1 o'clock on facebook. So is this correct?
Actually now that I'm looking at the photo it's nowhere near 1 o'clock... but that cutout seems to be in the right place more or less.
The other thing I'm wondering about is which wires do what? I have (for those with black-and-white computer screens) yellow, blue, white and black with a red trace. As far as I can tell it's got different colours to the other similar ignitions.
I read about the fairly low output of these ignitions and thought I'd add a battery and regulator like the BGM one. This should give me enough DC to run blinkers and LED panel lights for the tail and brake.

Managed to get a diagram from the guy at Avotecnica (the manufacturer?) which is great and I understand most of it but the bit down the bottom has me wondering... is it a switch? A headlight? Even my Italian speaking mate doesn't know what he means by that first word in the box. Semola? Scamola?  |

from the wires going to it i think its the light switch , an he's just not bothered to draw all contacts on it to keep it simple . i cant make out the 1st word ,an google translates mangles the rest .H

Da telaio translates as from frame ?

The other bit looks like Semolina & Fig :-)

He replied and said
not "SEMOLA"....but "SCATOLA".....BOX...
and then showed a picture of a junction box. Doesn't explain the headlight business though. Unless if the headlight is basically connected to the regulator then it's not connected to the stator?
Apart from that does anyone have an idea about the orientation of the stator? Is that right or do I have it upside down or something?

Looks like a vespatronic stator so would suggest starting with the normal position for that and then adjust timing from there. I should have a pic somewhere but I’m sure you can find one on google

Good idea Nick. Found this post when looking for pictures -  You have got it bang on there Mark, I thought the same when fitting mine but after a lot of research I found that it was correct. The important thing is to get the cut out at the bottom lined up with your casing. In your pic you have a crosshead screw/bolt holding your stator on. Take the screw/bolt and washer off and ensure that the cutout lines up with the casing exactly. Thats the perfect starting point before tweeking the timing for a vespatronic  I also saw this which kind of makes sense - I've built an engine for someone and it was like that didn't like the way it put pressure on the wires but i think thats the way its meant to go because the cutout lines up at the bottom, but i also worked on a engine Charlie Edmond's built and it was 180 degrees round and as it sparks twice this works as well. both engines ran well with no problems i either position I tried turning it around so that the black coil is in the opposite position and the wires definitely foul the case... that's apart from the cutout being in the wrong spot. So if the Vespatronic will run at 180 degrees rotated then perhaps that's the way this is meant to be. Once I assemble the whole thing then I can check with a timing light and no spark plug to be certain but at the moment think that might be ok.  |

I asked Avotecnica about the correct rotation of the stator. He sent me this picture which he says shows it set to 24 degrees btdc. |

It seems that Vmc dont bother whot instructions. I got the 177cc kit i while ago and no instructions what so ever

You get 2 sparks per rev so fit it any way you like
From memory the 2 stripey wires are ignition
Just connect them to the cdi. If the timing is miles out reverse them
I did my scoot 12v dc and made my own loom so I can’t help with the lighting side

Even my Italian speaking mate doesn't know what he means by that first word in the box. Semola? Scamola? Scatola fili dal telaio which translate to wires from the frame to junction box. |

Looking at the colours I think that's how he connects the engine kill switch

I have my stator in the same position. As yours,
I don't think he is the manufacture I think they come from a Chinese rev and go scoots

I believe they do originate from a 50cc motor Steve, of course the back plate, taper and flywheel still need to be manufactured.

Hi Guys, I am fitting a VMC soon and I wanted to check with you if this is the way to position it! |

Very happy  Thank you! |

mine is like that ( i think )
if its upside down it makes no odds as its 2 sparks per rev
if you turn it 90 Degrees you just swap the two ignition wires from the stator

Thank you!
