Electrex, Horse Power Ignition Stator Review

Electrex, Horse Power Ignition Stator Review

Stator failures are probably the #1 early Husaberg issue (1989-2003)

This is a review of the electrex and also a Horse Power Ignition stator for a 1995 fe 501.

Because I ride tight single track ( mostly 1st and 2nd gear) I am convinced that I am simply not getting enough airflow through the rad to provide adequate cooling. I have to add coolant regularly and I think that a fan is really needed for the way I ride. I think as others have said that high temperature is killing the stators.

I have tried several used SEM stators ( some purchased used and some from my own collection of vintage husqvarna's ) and all have failed, the longest survivor was maybe 2 months.

2 years ago I purchased a stator from Electrex in England, it arrived in about 2 weeks. 180 pounds including shipping plus 40 duty = $375 Canadian
They look really well made
All connecters and wire length perfectly plug in as stock. Claim 200 watts lighting if using a rectifier which is above the stock SEM of 140 watts.
The bike started right up, bike ran perfectly for about 2 years then the usual problem - ran rough when engine got really hot, and very difficult to start hot. Testing with ohmeter is normal when cold, Did not test hot.

I just purchased another stator this time from Horse Power Ignition. Belgium
These appear the same exact stators as electrex and the 2 websites claim the other as “Dealers”
This one is quite a bit cheaper. I paid 195 euro including shipping plus 18 duty = $283 Canadian
I ordered and paid on Wednesday, it shipped on Monday and arrived Tuesday (from Belgium to west coast Canada in one day!) Pretty hard to beat that. Bike starts right up and currently running perfect.

Summary : electrex and hpi stators work just as well as SEM, and from my experience last longer than original SEM, but ultimately they seem to not be able to handle high temperatures same as SEM. I would think that a cooler running engine would likely extend stator lifespan. Lighting power is claimed to be better. I had no issues with damaging the stock SEM cdi, and electrex websites claim - “This unit features built in protection to prevent damage to the original SEM CDI/HT coil. “

I have considered sending a failed SEM stator for rewinding a few times, but the cost of paying for shipping 2 ways is expensive plus there is a long turnaround time involved. I do not know if a rewound stator would last longer or shorter in my application.

normally these go because of the damp? not the heat? in my experience the electrex go just as often as the SEM units but again it is the damp.

finally, why are you blaming the ignition for rough warm running when in my experience it has been the carb? you haven't mentioned what you've done to your carb?

I've bought electrex for my older husaberg.
I don't agree about the quality in my opinion they look very cheap BUT the
price is good. Some ignition coils weren't well covered with factory isolation so i put a nail varnish (it could be anything else wire is very thin so they need proper isolation). I regularly check if there is no water under the cover and spray WD40
and i have no problem with this stator at all ( like 100 mth) for the price good product .

Confused? I am.
So many points of views & varied experiences. I have three (3) Bergs that are dead at the moment, purely as a result of dead SEM stators. One is a beautifully restored 98-FC600 (without the lighting coil), one is a 98-FE400E and the other a 2000-FE501E. The two FE’s have both had re-wound/re-built stators from reputable repair locations and have lasted less than 24 months, this with me sealing the covers to prevent moisture ingress (&) taking the stator cover off after each ride and letting the stator air out with a very light spray of water dispersing agent like WD40 or the like. Both rebuilt stators show no signs of rust/corrosion on the outer laminations but they do show signs of slight cracking. As we all know the biggest headache with the way these SEM stators fail is that for the most part there is no warning. You’re in the middle of the bush miles from nowhere and without warning you can’t start the bike. A few weekend's back this resulted in an 8 hour recovery to get me and the 00-FE501E out of the bush. To be honest if I had a lighter I would have burnt the thing to the ground and walked straight into Kawasaki dealer and bought a new KLX450R.

After settling down I now look to getting my beloved Berg back on the trails, albeit probably by myself as my fellow riding partners have said that I’m not welcome on the Berg anymore.

So I travel around the inter-web looking at options and it boils down to two (2) options, rebuild the original stator or fit an ELECTREX replacement stator.

I go to the ELECTREX web site and they say that;
• This stator has a controlled output which regulates voltage to prevent damage to the original SEM cdi/HT coil.
• Far superior compared to 'rewound' original SEM stators which are generally inconsistent quality and only repeat design defects inherent in the original stator design

Husaberg FE400 450 501 600 680 1999 2003 Ignition Lighting Stator NEW ST5410L | eBay

At a well-known (to all of us) web site it references.
“The SEM unit has regulated Voltage and will not damage the ignition module (known as ‘the coil’) whereas the well-known rival unit will. A new coil is 250 or 350 each. If you have a broken coil with the 'other' stator, we can now get them repaired to withstand their set-up. The answer is this rewind, and with a 100% reliability record it's got a great pedigree”

A quick run around the interweb and these guys come up but it just send you back to ELECTREX by default as they all appear to be resellers.

STATOR MOTOR

So who or what are we to believe?
For me it’s simple, I want to ride my SEM equipped Husaberg with a stator of some design or brand that won’t fail and let me down. I rode any amount of much older bikes (like my 79 PE250) for years & years and never had an issue. I’ve still got that same PE250 and drag it out for Vintage Enduro’s and it still goes every time I kick it.


How hard can it be?

Hi

I should state before this:
SEM stator and CDI repair - NEW - Nice prices

But don't think for this that I don't want ELECTREX/HPI stators to work well.
I just want a good solution for older BERGS that I also ride.

There has been reports of stators burning CDI's, but I've never seen one ELECTREX/HPI stator.

One thing that worries me is that for the 99-03 generation, you don't have a timing mark to set up the ignition advance, so how do you do it ? Probably you must have to try to make a new mark ?? will it be correct ??

Also, as far as I've seen the best way to protect your stator is the spray enamel, as kli suggested

2003 FE501 rebuild

I don't use the same brand, but it's a similar one.

I've had problems, specially with rewinds, from all (I think I've tried them all ) when I was using WD40 or similar ones.

I used to spray my stator every time I rode the bike, and had problems with the stator rewind new covers.

Now I've made a paper gasket for the cover and insulated everything (wires coming in) with silicone, and also used the enamel spray.

I don't remember now to take the cover out, and still without any problem

Hi Bahnsy I reckon there are 2 options ?

1 carry a spare stator

2 convert to kokusan

SEM KOKUSAN Conversion

Bushie,
I'd go the Kokusan in a heartbeat if there was an off the shelf option. Other than the work that you've done, are you aware of anyone that is doing a retail offer on such a conversion?

Im still running my 2000 FE501-E as a trailbike but i have the option of buying a real cheap 2003 FE501-E with all the 2004 updates (including the Keihen Carb) but obviously with the SEM ignition. With the SEM ignition on the 2003 model i dont think that i'm getting anything better than for what i need with the 2000 model, but that would be a differnt story with a Kokusan conversion.

not as far as I know Rod,

for a re seller type outlet to make a profit just the OEM parts required are about 1200 AU (stator, flywheel, ign, ign coil) plus the cover at say $300 and add any machining needed on the flywheel to fit the old cranks

if i get some spare time ill consider making the covers for about 200-250 but that leaves a lot of work still to be done up to the end user

since kokusan stators do sometimes fail you could argue though that an SEM bike that forces you to carry a spare stator in your pack is cheaper and actually more reliable

Bushie, 100% agree.

On a good day a 2nd hand flywheel, stator, pick-up, coil, CDI & wiring from a 04 to 07 model is $500. Add to that a (proposed $300) billet stator housing & another couple of hundred for machine work and youve got 3 x ELECTREX stators.

No issue for carrying a spare stator on a 99/03 model, but pre 99 you'd have to carry a flywheel puller as well.
