Which 12v Stator plate ? 64 LIS150

[johnny LIS150]

looking to upgrade my magneto to 12v but I'm not sure if there are any differences between the various stator plates out there except the prices lol.

With a battery-less 1964 Li150 Special do I just change the stator and bulbs ?....is that it ?
Where is the best source and price for a suitable 12v Stator ?

would any of these do ?

No, you an entire kit... electronic stator, electronic flywheel (to suit your crank!), CDI, regulator, bulbs, and associated wiring/junction boxes... and ideally horn. You also need the correct tools for the job (flywheel holding tool, flywheel extractor... and strobe). You also need to be able to find TDC, find your required firing point (to suit your motor and today's fuel) and to be able to check and adjust using the strobe mentioned above.

Pretty sure that's all you need.

Best of luck.

Do note, however, that there are various other options to go 12V and/or to get better lights. The stators that you posted links to are electronic stators that cannot work with your points flywheel. There is lots of info already on this site, which you should be able to search for. There is even info on the 'simple 12V conversion' that uses a 12V Vespa regulator to turn your existing 6V into 12V.

Lots of options but you need to decide what you want to spend, what work you can do with the tools available, evaluation your existing system and considering if you can get around any current issues, etc.

why do I need a regulator Adam ? I'm not running a battery so I don't need to convert the AC to DC and I'm not using the charging section just the coils that provide a spark and AC voltage to the bulbs .

well thats what I am asking advice about I don't know what the various options are nor what might be best for my particular application. Thats what I am asking advice about really .

[Adam_Winstone]

A regulator stops surges on a non-battery (AC) system and stops bulbs from blowing, which is not the same function as a rectifier, which changes AC to DC for a battery system.

Yep, I get that and am simply pointing out that you don't want to buy anything until you figure out exactly what you want to end up with and how much you want to spend to achieve it. You can very easily buy the wrong thing on-line (e.g. many of the Indian electronic flywheels are aftermarket and have the wrong points flywheel boss in them, meaning that you cannot set the ignition timing correctly until you modify your new purchase ).

You've come to the right place to ask the question and I hope that others will give you their opinions of what is a good option and/or what to avoid.

you're quite right Adam but I don't know enough about magnetos yet so I need to do a bit of reading so that I understand the topic better and can ask some sensible questions lol

I saw a couple of 12v Stators going really cheap and so I thought I'd bid on one and see if I could use the coils to adapt my 6v stator . For £5.00 it seemed worth a punt.

Thanks for your advice and suggestions.

No problem.

Many people look to change to 12V electronic kits to improve on unreliable ignition. Others change to 12V electronic kits because the lights are so crap on their 6V system... but the ignition might be fine. Others have such old and knackered 6V systems that they change to 12V electronic kits to avoid both ignition and lighting problems!

However, that's not to say that you must go 12V electronic. Many 6V systems have poor lights because the flywheel has lost some of its magnetism but this can be remagnetized by a number of dealers that have the original workshop tool specifically for that job. With a remagnetized flywheel some people then better understand that the original 6V system (in good condition) isn't actually all that bad.

However, the 6V systems are not as good as 12V for lights... but, if your ignition is working well then you can look into the 'simple 12V conversion' that I mentioned earlier, which keeps your points ignition as it is but uses a Vespa regulator to convert your 6V lighting to 12V lighting. This system can work very well, however, if your flywheel needed remagnetizing before then this hasn't addressed the issue and output will still be pretty poor. You will also find that wattage on this system is low and that the headlight will dim when you put your foot on the brake and the brake light takes power away from the headlight, etc. Again, there is already quite a bit of info already posted about this conversion and ways of improving it (e.g. LED rear light bulbs).

Then you've got the full 12V lighting + electronic ignition systems that I've already touched on... but these do need to be swapped out as a kit, rather than one or 2 parts. You cannot mix and match items between points systems and electronic systems. There are lots of ways of upgrading to this spec and many people opt for ripping out the entire loom and starting over, however, there are also a number of ways to keep your loom and just change junction boxes, etc.

There really are many ways to go about such conversions/upgrades... BUT ... that also means that there is not one simple answer that anyone can give you that answers your question. If you give people a better understanding of what your system is, what problems you have with it and what you want it to do, the people can tailor their response to better suit your needs.

Best of luck.

thank you Adam for such a detailed and informative reply.

I'll hold off on doing anything for the time being until I can run and assess the existing 6v system. I am trying to read up on the subject and have found a couple of informative articles .
I haven't found any articles on here yet but I haven't really done a thorough search yet.
thanks for all your help its much appreciated

The other thing to do is to make contact with scooter clubs local to you and to see if anyone can spare the time to have a look or help as/when they can.

Cool... good luck with it and keep asking questions as there are lots of people on here that might be able to help.
