An older Valeo. I have a Bosch on the shelf though ...
never seen the inside of a Valeo before. Those are the infamous failed magnets?
Ditch the can and bolt up a weedwacker engine?
any chance that this was caused by a Bendix not disengaging and turning the starter into a generator ? At least for a little while
Yep. And spectacularly failed as well.
Don't tempt me. Those Honda small engines are bullet proof.
It's a possibility. During the analysis I was suspecting my 2 year old Odyssey Battery ... when I looked at the voltage it was reading 11.2. I thought I had blown a cell. Switched the battery with a charged one ... it didn't even turn over the engine. I had the Odyssey on a drip charger for two days and it was finally charged ... constant 12.8. Then I began to suspect the relay, then the starter. I took out the starter and found this ...
So now, we'll get her running and see if the charging system is working properly.
If the rest of the starter motor is still good, then you can just replace that portion of the starter. The replacement has clips to stop that sort of thing happening again. $35.00 isn't a bad cost. The Bosch is a much slower wind over, & pulls much greater amps to do so. The new magnets fix the Valeos greatest weakness.
I had good luck with this company and the price was really good. It spins the starter much faster than the older Valeo and uses less amps.
Yep...my oilhead had been defaulting the ABS almost every time at the end of the year last year. That's a sign of low voltage. A friend had an oilhead that would barely start his bike. He replaced his with a new valeo starter and gave me his to pull apart. I pulled it apart and it looked just like your magnets. I began to think maybe my starter was having problems. I then pulled mine apart and replaced it with an updated case following Anton's sight. I only used the bike twice before putting it away for the winter and I had no defaults. The rebuilt starter spins much easier. It took about one hour: pretty easy.
Ooooo ... SNAP!
Very strange, a couple of days after reading this thread I experienced the same problem.
We were lucky to get a really sunny weather through the Easter holidays and I thought I'd take advantage of it. I rode out to my friends on Sunday morning planning to take a ride through the Fraser Canyon. I parked the bike briefly as my friend got his shit together and as we were set to leave, I got the same " Click, Click, Click " followed by a WTF.
Not wanting to waste the riding opportunity we bumped the bike and headed out for the day. I was careful the whole day not to stall and always stopped on a downslope, which worked out great, and a fun day was had by all.
Fast forward to this morning and I thought I'd do some problem solving. I took off the tank, followed by the air box and then removed the starter to find.
Look familiar ?
I'm hoping that it is just the magnets, and will go the EME route with the $35 replacement cap.
How can I test the Armature to make sure it is still in good shape?
Sorry to say ... but YES. Good that it didn't leave you stranded.
Me too. I ordered the new replacement cap, and we'll see. I figured it's worth the gamble.
As for testing the armature, I am taking a $35 dollar gamble with the new part. I'll bet there is a way to test, but I don't know how ... anyone out there have a clue? I'm guessing that the only thing you can really test is powere through-put to the brushes ...
Start with a visual inspection and verify that the brush contact surface is smooth and level. If the grooves between the segments are level with the segments take an old hacksaw blade, grind it to the same with as the groove and run it between the segments until the grooves are at least half a millimeter deep.
Now check continuity between the segments with an ohm meter set to the 1 ohm scale. Make sure you don't have any dead ones, resistance should be less than a couple of ohms between segments. You should not have continuity between the segments and ground, i.e. the core.
If it checks out, polish the armature with some fine sand paper, clean the dust out of the grooves you just cleaned and reassemble.
After you put the starter back together make sure that you get the same resistance through the brushes.
I've got a Valeo where the magnets are good, the armature is questionable. The gear housing at the end of the armature came apart. Are you interested in it?? Would have been cheaper than $35 too a lot cheaper.....oh well.
OOOP to late you already bought one,
Came off a 2004 R1150RS, I thought the battery was dying, then replaced the battery and the same problem didn't have a clue FINALLY looked at the starter to find the gear reduction housing had come appart and was either binding or shorting out the armature.
I've used Discount Starter and Alternator for a number of purchases, customer service and products have been awesome!!
Won't work for an airhead. The polarity of the magnet is reversed so that they rotate the other way...
thks. had me thinking
always a bad thing.
Wow!!!!!!! Great info!
On closer inspection the armature is also badly damaged. The loose broken magnets seem to have taken quite a few chunks out of the communicator bars.
I may bite the bullet and buy a complete starter. EME have them on sale $189, compared to our local independent Airhead repair shop who want $420 for the exact same part.
on E-bay. Sounds too good to be true, but even if it only lasts a year..............

Statistically speaking probably worth a risk.
