Thanks for that,

I think I ordered the AS3,RD125 kit,

But the stator doesn't match the mounting points, looking at the other kits, I think I should have the 1E7 kit,

See
 Pictures,

Does anyone know about the regulator/rectifier?

At present I have a rectifier  with a resistor under the battery box.

My kit came with a new rectifier/regulator unit, making the existing seperate ones superfluous. I fitted mine where the old rectifier was originally, although to do this, I needed to drill a new hole for one of the mounting bolts.

As your bike isn't quite the same, this location might not be possible for you.

My thoughts as well,

Fitting the coil is interesting,

I was going to fit under the frame tubes not far from the front tank mounting.

I initally put the coilpack where you say, but had a problem with the fuel tank balance pipe being an awkward fit, and the throttle cable being fouled.

In the end, I fit mine to the central tube, as far back as possible so it doesn't clash with the throttle cables going to the carbs. I used steel cable ties to fix the coilpack to the tube, with some some fabric harness tape to protect the frame and provide some cushioning, but you could make a bracket which I think would be better. Because of the need for an ground connection (I think), I attached a ground wire to one of the coilpack mounting holes and ran it to a fixing point elsewhere on the frame.

I had a look at mine today. I couldn't find the puller so couldn't take the rotor off.

These two photos show where my stator screws in:

101330-0

101332-1

This is one of your pictures. I've indicated where I needed to take off about 3mm x 3mm from the end of this part so the stator would fit:

101340-2

This is a photo of a 1E7 crankcase I got off the internet. The arrows show where the bolts go in:

101342-3

As none of your photos are taken side-on, it's not possible for me to see if your holes are in the same position, but hopefully you'll be able to tell yourself.

Check these,

The one shows the standard stator screws in place,
The other the standard set up

It's hard to be certain, but it looks to me like my (new) 1E7 stator would fit your bike. Can you post a pic of your new stator so I can see how much different the mounting points are?

I ordered the AS3,RD125 set
71039900 as reccomended by Spa motorcycles

I think I should have ordered the latter 1E7 kit

Although the bike has an AS3 prefix numbers

My three mounting points are about 120 deg apart, with the pickup at the top right (orientation isn't important, but any other way and the pickup won't fit at all). You stator looks like the only use of three holes approx 120 degrees apart would put the pickup at about 90 degrees where there's no space at all.

This is a portion of a AS3 parts list showing an AS3 crankcase:

101349-0

It's taken from here:

https://www.yamaparts.com/pdf_manuals/AS3_parts.pdf

The differences between an AS3 crankcase and a 1E7 one don't seem to be a lot.

Looking at the kit for an AS3 on Vape's website, it looks different from yours:

101351-1

There's a partially obscured hole on the one shown above, which I've indicated with an arrow. This hole is present on mine in that location (and is used as one of the three mounting points), but on the stator you have, this hole is in a different location - it's at the other end of the pickup, and partially obscured.

Did Vape ever get back to you? Maybe they packed the wrong stator, or sent you the wrong kit?

Edit - is there another hole underneath the pickup?

Yes, we are chatting, I am sending pictures etc

That is why I show the part label of the stator

They asked me to loosely assemble the stator,

So I checked the fit,

I marked the location of the mounting screws on the cases in green ink,

And were the holes should be in red.

Let's see what happens now,

I got the rotor off mine today. Here's a photo for comparison:

101401-0

Regarding the rectifier placement, this photo shows how I mounted mine:

101403-1

You may need to be careful that the rectifier fixings don't touch the the tank.

Edit - when I took the cover off the rotor housing, the bottom allen screw was sitting in the bottom off the case, and I'm sure I tightened everything. So I put medium threadlock on all the fixings.

Thanks for that,

At present, my kit is on its way back to Czech republic,

They are changing it for a different system, brand new,not on the website yet,

Code 810379900,


Also, my tank is held in place by the seat front,

I shall let you know what happens,

I should really send all the pics from the last 5years, and a narrative to Del for Well-ard.
