Starter motor won't turn the engine.

Hi, all.
I was riding with friends a while ago and after a pit stop, my bike wouldn't start. I bump started it and rode home.

The starter motor spins but doesn't turn the motor. I opened the left cover today. (You DO have to tqake of the clutch slave cylinder!)
Everything looks OK:
The one-way clutch spins freely clockwise.
The gears don't have any missing teeth.
Everything seems to be meshing, all washers, spacers, etc are good.
The starter motor spins both ways by hand.
What could be the problem? Maybe the torque limiter is bad? Or the one-way clutch doesn't lock up CCW?

I tried to run the starter by itsel, to verify that it was turning the correct direction.but with the cover off, it wouldn't run.

Since I had the cover off, I checked the magnets. Crap! One of the magnets has slipped! I guess that I should purchase some JB Weld!

Also, I cleaned off the grunge on the clutch push rod and noticed that the rod has a direct access to the drive sprocket and chain. Why wouldn't a moving part like that be protected from the oil & dirt flung from the chain?

What does your battery voltage look like under load?

Well, I don't know. The starter motor spun "vigorously". It sounded like the motor had juice, but wasn't connected.

If your battery is good, this is an interesting thread to check out: https://www.sv-portal.com/forums/4-s...onnection.html

If you take out the sparkplugs, put it in gear and push it backwards you should see the one-way clutch working (if it is). If you can push backwards without it spinning the starter motor....the one-way clutch has a problem. Not a real common problem...but has happened here and there. You didn't just happen to change the oil....did you? The clutches rely on friction and too slick an oil can cause them issues.

Thanks. Ill try it.
I haven't changed the oil yet. It was just changed before I bought it, and looked it.
This will be the first time I've looked at the plugs, also. I'm getting to see different parts of the shop manual! (And the bike, also!)

The clutch push rod has a seal on it at the sprocket end as it enters the case....
Giving it a clean is a good idea anyway......

Not yet. Life got in the way. I put a cover over it and am waiting for the right minute. One problem is that I have another bike, a 14 Ninja 300. It's a pleasure to ride. The SV is not as easy to ride and, w more power, a little scary. (But SO fun!)
I've had two accidents since I got the Ninja in late 2016, BOTH on my bicycle!

...soooo....your Ninja has been riding your bicycle?

As far as power, the SV will only bite if you dont pat it and brush it regularly.....
