Re: RE: Re: Replace the SEM no more!

Hi,

Regarding the disscuion on the KTM SEM stator fitting on the Husaberg, anything pre 1999 will work as the KTM stator had the same resistances, but from 1999 to 2003 The resistance changed to 3000 Ohms source and 165 Ohms trigger.

Sparks.
 
RE: Re: RE: Re: Replace the SEM no more!

Once and for all we need to know if the old LC4 SEM stator can fit the -03 Bergs, yes or no, and if yes, with which modifications, if any.

Then we should be able to bury this recurrent running gag of a topic into Taffy's Wiki (*)

Thank you very much for the collective effort.






(*) I hope this does not sound too kinky.
 
RE: Re: RE: Re: Replace the SEM no more!

For the values I measured for a new LC4 stator, part number listed in this thread, go the the "questions about ignition coil" thread.....
 
In case someone finds this thread and reads it without reading the other threads on SEM's, here is an update to correct things. This thread was in reference as to whether a KTM LC4 stator will work in a 99-03 Husaberg, but it ended up fitting the pre 99 bikes. Sparks made it clear that the LC4 stator is mounted in the ignition cover like a 99-03 Berg but has the lower resistance values (and lower voltages) like that of a pre 99 stator. He also made it known that Pre 99 coils must be used with pre 99 stators and 99 up coils must be used with 99 up stators. Was some question if the KTM stator would work when mounted in a pre 99 Husaberg as it will now be attached in the case rather than in the ignition cover. The answer was yes it will work ok when flipped to the case mounting position. KTM LC4 stator Won't work in a 99-03, but Sparks can rewind them for around $200. Hope this helps.

RE: Re: Replace the SEM no more!

I tried the link to other forum threads above and coudn't access them. I think it would be expensive to ship a stator overseas for repairs and get it returned. So I am interested in any option. Last posts seem to advise KTM is not suitable for my 99 600FE is I need to replace. Optimistically waiting for someone to refute this :)
 
AussieForce,

As DSDucati says, "KTM LC4 stator Won't work in a 99-03" They do work, with achange of connectors in pre 99s. I can personnally verify this. Small Coil Rewinds in Geelong can probably help you out.

I myself have been trying to get the LC4 stator to work on an 03 Berg for a few months. I can get spark, but it's very weak and not nearly enough to start the bike. This is just my experience so far.
 
Re: RE: Re: Replace the SEM no more!

Hi Aussieforce,

Sparks here I do the rewinds on the SEM ignition stators and people send them to me from all over the world I've been rewinding them for 15 years with exerlent reliability.
I will rewind your stator for 190 Euros including return post which works our to $314.
Check out JoeUSA's report on one of my rewound stators it's under the heading SEM stators.

Regards

Sparks.
 
Got the two ignitions by post today back from Sparks.
Went to my mate and fitted it on the 501 straight away.
It is cold out here and the battery is dead, however, three kicks and it ran.
Will fit the other one on my own 400 tomorrow.
This weekend we go out riding, so will let everybody know how it went.

Regards,
Arjen (Also a cheesehead...)
 
i'm sure sparks would agree that good jetting will help the bikes start easily. good to have a good ignition but don't blame this for all your woes. i can make my SEM bike start 2nd kick after a week off. getting the choke jet right is critical to good starting.

the choke jet of choice on the dell orto's is usually a 45 for the K51 needle or can be a 40 in warmer climes and if you don't run a K51.

for those that fitted FCR's which is quite a lot of you - the choke jet needs to be a #75 or an #80. if the third needle letter in the code is M, N, P it'll be a #75 and if it's a Q, R, S, T then an #80 would be better.

follow this jetting thread to pages 3-4 for more detail here

regards

Taffy
 
Today i fitted the other " Sparks" SEM repaired ignition to my 400 and it also runs fine. Nice bright spark and no problems starting the engine. Great work so far Sparks!

PS, the Spanish post is much quicker than the Dutch one!
 
Hi Sparks,

Thanks for the interest, the engine (2003FE400E) runs fine. Strong spark but the starting is still so so. Must say that it never started of the E-start from cold but it now starts second kick every time. Re-start when hot is OK. I am still sorting the starting out and planned to pay attention to it with the aid of the download on this forum. My mates 501 starts just as before with your rewound SEM, so perfect (even without choke). It makes me jealous, because the 501 allways started better. My engine now feels reborn! I think that it also has to do with the fact that although my SEM was broken, it still ran (when i could get it started) but with a very weak spark. So at high revs it ran, but not very nice. Now the power is back 100%! I am very sattisfied. Just another question. should the button be on Hi or LO for starting? Should it make any difference. (my button is broken)

Arjen
 
The button should be on "HI" when starting the bike. I just installed a stator rewound by sparks as well. My bike has been sitting for over a month and it starting 3 or 4 kicks. I won't be able to ride it for some time as I'm doing my winter maintenance. The stator was in transit for about a week, not bad for a Spain to Michigan shipment!
 
Hey guys,

A few days ago, I had ordered the KTM 58031002050 stator. The stator comes in and I picked it up. Well, one sticker on the box it has the above part number. Another sticker, which has the bar code has 50339004200. Is this a superceded number? It must not be the same as what you guys have gotten. Cause it sure doesn't fit. I guess I will have to call my KTM guy tomorrow.

Just to prepare myself, does this 58031002050 stator that you guys have put in the early Bergs look like the SEM stator that came out of the Berg?
 
Hi,

What is the year of your bike?, if it is pre 1999 then the KTM LC4 stator will go straight on and work ok. If it is 99 to 03 then there isn't a direct replacement but I can rewind it for you.

Regards

Sparks.
 
Hey Sparks,

The bike is a 1998 FE501e. I went down to the KTM dealer today and presented him with the stator I purchased a few days before. I had explained the situation. I had him look up a stator for a 96 KTM LC4 and then he was convinced that I did infact receive the wrong stator. I left the wrong stator there and he is calling the distributor tomorrow to pull a new one and visually verify that it is the 58031002050 stator.
I do have a 99 FE400 ---luckily, it runs like a champ.

thanks,
 
Hi Kzoo,

Sorry this is a bit late, it doesn't matter which position the switch is in there is no advance on either HI or LOW until around 3500 to 3750 rpm.

Regards

Sparks.
 
I just installed one of Sparks rewound stators.....it works great!! Thanks Steve!! Just one more satisfied customer :D

Sorry to reopen an old thread, but the difference between stators up to 1998 from those from 1999 to 2003 has been hinted on by Sparks, but I can't find anywhere that the differences are made obvious. The resistances above refer only to the '99-03 stator. As best I can tell, The Doc quotes these only and may mislead people with earlier bikes.

Apologies if it has already been covered & I just can't find it....

Last night I was replying to dz1 about his stator in this thread and compared the service manuals for the '98 and '99 models.

Resistances quoted for the 1998 model are:
Red-to-Black = 1.7 k ohms
Green-to-Black = 27 ohms
Both readings are + or - 10%

These resistances are and most likely the same for them all back to 1989.

NOTE THIS IS QUITE DIFFERENT TO THAT FOR THE 1999 TO 2003 MODEL ABOVE!

There was a significant change in the ignition between these two years. The '98 stator bolts to the crankcase, the '99 bolts to the outer side cover. I guess the gizzards of the stators must be completely different as well.
