That's just under 80% charged, so there's some reason it's not at 100% (12.7+).

What is the issue currently?

Maybe because of too much cranking the other day, and didn't recharge, but anyway it should start with that voltage, or am I wrong? Grinding sound still present a little bit, and it's cranking kind of slow, unballanced so to say

Yes, it should still crank decently.

I charged my battery when I got my SV out of storage, but it was still hesitating before it started cranking even after a few rides. I put it back on the trickle charger for a few hours and it now cranks normally.

Still not sure about your grinding issue.

I'd still recommend digging into the starter clutch, bolts in back may very well be loose. Could be the bic pen springs fatigued too. Both/either will create that startup grind.

Ducatiman, is there a how-to for checking starter clutch here on forum?

read up, do your homework before digging in, a proper EX500 flywheel puller and clean, organized workspace are essential

Accumulate or have red loctite (or equivalent) to apply to bolts if loose, some form of sealant for the LH cc cover, and a torque wrench to tighten the flywheel bolt to spec.

An assistant or helper always good to have too.

As a flywheel puller I can use spark plug wrench?

^ Not a spark plug wrench. A spark plug thread chaser. Can get one at an auto supply. I forget the size off hand, but it would be the diameter of the threads on the spark plug we use.

Took the cover off, but couldn't get the bolt off. It's the lefthand, right, I should turn it clockwise to loosen it? Two pieces of magnet are missing. When I crank it, the clutch is Just turning left and right a little bit and the flywheel is spinning ok. Why?
When I turn clutch by hand it Will turn clockwise only, without flywheel , and when I try counterclockwise it's hard to move it and it spins with the flywheel only. If I solve the clutch, it would fire up even if part of magnet is missing, right?

Yes, you will need to turn the flywheel bolt clockwise to loosen it. You will also need to hold the flywheel from turning while doing this, or use an impact driver.

Edit: I assume you have a bike made before 1994, is this correct?

Yes, it's 89 model. Couldn't loose the Bolt, it's to tightened. I am holding the flywheel, but nothing. Will try again tommorow with New wrench. It will go off eventually. @bpe,what about other things I've mentioned?

^ Your starter clutch is working properly. That's not to say there aren't loose screws on it that will need to be addressed. But that will have to come off any way, you can inspect it then. The whole magnets-a-flying issue, not a good thing. That is what needs to be fixed. You could replace with another gen1 flywheel like you have, and run into the same issue again later, or do the more accepted gen2 flywheel mod. https://www.ex-500.com/37-how-s-fyi/...-bike-fog.html
As far as getting the flywheel bolt off, if your holding the flywheel, you should be able to break the bolt loose with a breaker bar.

Ok, thanks. But something is keeping the clutch from turning the whole way around to start the engine. It's Just moving a little bit left and right.

bits of magnet maybe just a thought. it may also not be helping the starting. it goes something like this magnets missing so the stator may not be sending the full voltage to the RR which in turn won't charge the battery fully only partly. a partly charge battery may have difficulty starting the engine. yes.

and you can check AC voltage output directly from the stator , disconnect its plug ...using voltmeter set to AC volts....running bike, checking pins 1-2 then 1-3 then 2-3 revving bike to 4000RPM should yield well over 60V AC from each leg (maybe someone can check service manual for actual book value)

Known as a "stator output test"....an assistant at the throttle will be helpful, you've then checked output on all 3 legs

With magnets flying, I believe you're gonna come out shy on this test, undervoltage at 1, 2 or 3. Ideally should be equal (book) value.

The only difference in your description and the FSM is output should be about 60v AC, as opposed to well over . And they call it an alternator voltage output test instead of stator output test. Which I know doesn't make a difference, just keeping the record straight .
