Does anyone have the performance stator sold by Partsforscooters? I'm curious to see if they experienced any performance gains due to the flywheel possibly being lighter or? Also, did it help improve charging system capability? What exactly makes it a performance stator?

I did not look under alternator. looks like an 8 pole stator, hard to say much else. if there are more windings you may get another amp or 2. PFS in general deals in high quality parts and backs what they sell. if you post in the thread I linked, you will get a real answer. no BS sales hype. the posts are open for all the forum to read and they know that. most 8 pole stators are 1/2 wave single phase and have low 12 V DC output at low rpms. 8 pole 1/2 wave basically "wastes" 1/2 of the stator output.( modified 2aug11) if you need/want better electrical output, consider an 11 pole conversion. 11 pole is 3 phase and full wave with better low rpm output. in general an 11 pole will almost double the usable 12V DC output over an 8 pole. here is a link to a post I wrote sometime ago when I was looking to upgrade. scooterrebels.proboards.com/index.cgi?board=general&action=display&thread=1581 |

shadowwalker - You might find this disappointing, but I'm not really a "marketing speak company rep" kinda guy. Most of the people here on this forum I think would agree that I shoot pretty straight on behalf of PartsForScooters.com.
This being said, the only real performance gain that this stator has is what you've already stated. It is quite a bit lighter and smaller than the stock stator with similar output to the stock part. This allows the engine to spool up faster. We used it on our drag racing scooter and it does make a noticeable difference, but isn't the best "bang for the buck" option to get more performance.
It is a good option if you've already performed most of the other bolt on scooter upgrades.

Have you found an 11-pole for a 50cc engine? I ask because all I find for 11 pole is for GY6-150, and if we're talking 150's, the statement about all 8 poles being half wave is incorrect; there are full wave floating ground stators. You'd need a multi-meter to tell them apart from the half wave types.

have I found 1 ? no .
I have checked quite a few on ebay looking carefully at photos for mounting hole spacing, etc since there is little information other than the wire colors and over all size. I do continue to look
I have found several threads from yrs ago (08 or so ) where people say they have an 11 pole stator on 50cc engines & I assumed (we know where that gets you, at times) that there are some out there that fit.
Dcat, as usual you are correct in that some of the 150 8 poles are full wave.
probably the simplest way to get more 12 V DC is go to an 8 pole modified stator and use the TrailTech regulator rectifier.
I do not do much night riding at present ( long summer days) so have not pursued making this modification, yet.
as the days get shorter (Oct or so) I will go ahead with this conversion on my 50.

ill say the same thing i told the other guy stators are not car alternators and you have a tiny battery. the only real way to get the max from your power supply is to use like a led headlight to draw less power for the same brightness.

led headlights do not work. they do not project enough light to see the road.
plus & this is a big plus.... stock headlight circuits are AC from the stator.
to use LED or HID lights you need 12V DC.
this is the reason for the conversion---- to get the 12 V DC

then you got a crappy led. gotta watch that i have seen those things bright enough to blind you. but i also seen crap ones that are not true white etc. they come in ac as well. but for a good led your gonna drop some cash probably in the 100$ range last time i looked for a good one that is bright. and can cover enough distance..

I meant no disrespect at all I just wondered if anyone had any real world performance feedback. Stating you used it on your drag bike with favorable results gives me confidence that when I order it it will work well. I appreciate everyones input on this. I have performed pretty much all the bolt ons and am still in pursuit of more power. |

For that kind of money you can do much better and actually get some performance from your 139.
Sorry but being lighter is not enough to make it noticeable, put up the lbs the stock one weighs and this so called performance stator system. Also that fan does nothing over the stock fan. If your looking for more power or top speed it will not do squat. You will be wasting your money if your looking for more speed and or power.

shadowwalker - Oh, none taken.  With the amount of corporate speak that goes on I completely understand your stance. edfr - I'll stand by my earlier statement. We did see improvement on how fast the engine spools with the lightweight stator kit, but is by no means the best bang for the buck. I'll post weights when I find the time to dig up the stock parts from our drag bike. It has been a year + and a company move since I have seen that particular box of parts. The flywheel is one of the heaviest moving parts of a scooter engine and any weight reduction and moving the weight closer to the center of rotation will have an effect. This part does both. Matt |
