1998 FC400 with bad stator black/green 165ohms, Black/red 200 ohms. Can I swap in a 2001 FX470E stator? Do I need the flywheel as well? thanks
 
Hi

Those stator are diferent.
You can not interchange them.. sorry :cry:

Zaga, I realize the 470 has a lighting and E-start and my FC 400 does not. R U saying it won't work because of the lighting coil/e-start I thought I read before the To switch from FC to FE just plug and play
 
No, they are diferent, they have diferent values.

I have both models one from a 98 bike and another from a 02 bike, and they have diferent values !

Go to the owners docs and check it.

You have 3 simple options: buy a new OEM (here in Portugal you can only buy it complete with flywheel), send yours to sparks to fix it, or buy one from HPI or electrex (its the same).

The first option is the more expensive and you have no guarantee that it will last longer, you have the advantage of having a new flywheel (they also loose their gamnetic power, then less spark)

The second worked fine for some time but it didn't last as I would expect, don't know if its my foul or ot ??

The third option I haven't tryed yet, but want to, using that stator some say it makes peaks of power that can burn the CDI, so you should fit a extra protection (let me know if you go this way I send you a drawing of what to do)

Now just think about it, and prepare your wallet.. :mrgreen:

Forgot that there are more complicated options like the transformer mod of OYK and other things that I'm reading but for now I think you shoud keep with the simple solutions.

a 98 stator is behind the flywheel and is not an electronic advance. an '01 is mounted on the cover, uses electronic advance, rotates the other way, needs a different coil, etc. if you are looking for a replacement, look '98 down.
 
The stator is mounted on the cover. As I understand a good stator measures red/black 3k ohms and black/green 170 ohms. My black/green is good at 165 ohms but of course the red/black is about 205ohms. This is why I thought the 01 stator would work because what I've read in previous posts is all 1998-2003 stators have the same ohm readings.
 
HI

But in the 98 the stator is mounted on the engine !

Pay attention to the years of the bikes, because in 99 the stator was mounted on the cover.

What year is you FC ??? 98 or 99 ??? It is important because it was the year of the change. Its 99-03

I don't have a title for the bike but the head is stamped 1998. I've had the cover off and the stator is definately mounted to the cover. The bike could be late in the production yr and could be a 99 model.. Am I correct for the stators all being the same going forward to 2003? Getting back to my original ? Do I need the flywheel from the 01FX470 to use the stator?
 
Hi

If the stator is on the cover it's a 99 bike.
The cover is aluminum not plastic so it's a 99 period.

So your stator is the same until 03, the other question is if they look the same? because your fc stator can be the thin and the one from the fx can be the fat one. One makes power to the batt and the other don't, it's half stator..

Usually when you have the half stator you have a spacer inside, don't know on the 98 bike. I know one 470 fx 01, with the small stator and the spacer.

Please check how they look

Zaga , Now we are clear it is a 99FC400. The stator from the 470 that I'd like to switch in for lights is fatter. My question is if i installed the stator into the 400 and used the matching stator cover would the bike run with my flywheel? Also, I assume I'd have to change the flywheel as well if I wanted to get lights. There is a spacer on the cover for the 400 but is cast and not removable to fit the fat 470 stator.

Maybe someone out there has a stator for a 1999 FC400 and at least get up and running.
 
HI

The cover has what you call a spacer but thats for every bike, its the mount of the stator and its part of the cover, to use the thin one you need to add another spacer that is removable, so the stator is completly iside the flywheel.

The thing is, if you have the thin one without the removable spacer, you don't have good spark, maybe thats your problem !!!

The other question is, to put the large stator with the FC flywheel, it could be possible, you just had to make sure the flywheel dosen't toutch the stator, but for sure you won't have lights, because there are no magnets for that part of the stator.

In every case the stator has to be completly inside the flywheel for that part of the stator to work.

Don't know if it I answered you questions, but let me know.

Hi

Just for you to know what I'm talking about, I've took some pics:

This is the ignition cover with the "spacer", that is part of the cover, not removable:

The spacer that I'm talking about, the removal one, you can check on the owners docs, under electrical. So I don't have to take a stator out :) to make a picture.

And here it is the flywheel large (FE) and small (FC):

Hope this helps to clear things.

Zaga, I'll remove the stator again to check for the spacer. Either way the black/red is only around 200 ohms. If the spacer is not there I guess I have to find a FE stator to get the firing portion of the coil in the proper position in the flywheel. Am I correct?
 
HI

With that value, the stator is not ok, spacer or not. So you change it with the FX, or try one of the solution that I've told you earlier.

If you try the solution FX you don't kneed any spacer because its the fat one, I just never tryed it with the FC flywheel. It should work the ignition, but no lights. Please be carefull, put the stator and turn the engine slowly to see if anything touch, then check if you have spark.

If you go to one FC stator solution let me know so I measure the spacer and send you.

Good luck JIM ! (SEM stators are somehow like misson impossible) :mrgreen:
