replaced starter, no start

I replaced the starter with a new one and it is receiving 12.6 + volts. When I try and start the bike I can hear the jack shaft slamming into place. When I use the slam button all I get is a whine. The engine does not attempt to turn over at all. I can hear the compression releases kick in. I've exhausted my knowledge. Any help would be appreciated.

Make sure the main power wire is strongly secured to the battery post and the starter post. If all is tight Take the starter back out hook the power back up and hit the starter button to see if the jack shaft engages and starter spins freely. If so hook it all back up and try again. If not take the switch apart at the handle bars remove the board and clean both contacts with 1200 grit sandpaper and try again

Did you tighten it up square in the hole? Battery ground cable attached to the mounting bolt?

I took the starter back off and left it hooked up. The grounding cable is secure to the mounting bolt. When I hit the start switch the starter jack shaft extends and it appears to spin for just a split second. I tried this several times and it repeated itself consistently. It sounds exactly the same as when it was installed.

To be clear, this is a brand new starter. The jack shaft extends and the gear spins for a split second when the start button is pressed. I thought this was normal. My next step will be to take the primary cover off and take a look at what is exactly happening.

Please allow me to give a back story. My mechanical ability is fair, meaning I can research something and follow instructions lol. My starter would stay engaged and melted a battery down. I took it to a dealer who changed the solenoid and added a slam button. It worked for a week and did the same thing. I took it to a shop who cited a voltage drop and added a starter relay. Two weeks later the same thing happened.

I took apart the handle bar switch and it appeared fine, a little rubbing on the board but nothing bad. I tested the solenoid input voltage while engaging the start button and it was 12.6 + volts. I took the solenoid apart and there was pitting so it was replaced. I tested the voltage where the positive lead enters the starter as the start button was engaged. This read about 6 volts. The relay installed by a local shop tested fine. The starter was removed and hooked directly up to a battery. The gear spun without the jack shaft engaging. I ordered and installed a new starter. When I hit the start button the jack shaft engages with authority but the engine does not even attempt to turn over.

What has me curious here is you say ot spins for a split second -- it should spin till you release the start button.
If you are still holding the start button and it stopped spinning, there's you're issue.

Put a socket on the engine pulley and see if you can turn over engine by hand (with bike in neutral), you can pull the spark plugs to make it easier (release compression)

OK, thank you. When I hit the start button I can see the jack shaft move outward then spin for literally a split second. I am not sure it even spins but rather moves.

Let me walk through this to be as detailed as possible. I turn the ignition on and the bike lights up as usual. I press the run button followed by the start button. I can see the jack shaft extend and the gear move for a split second. see attached video at

Doesn't look like the starter is fully extending but I can't tell by the video if it's because it's hitting the inner primary?

But actually, if it's not bolted in your missing a ground connection! So it won't ever work. Ground hooks up the mounting Bolt.

It should stay extended until you release the start button. Take the starter out and activate it off the bike and take a video. A set of jumper cables + on stud and you can just clip the ground to the starter case Bolt hole and just a wire to touch solenoid

Agreed you need to remove the starter and make sure it is grounded to the bike and hit the button. It doesn’t look like it’s getting all the power it needs to fully engage it

I have seen this before and usually just putting the bike in gear and rocking it back and forth to get the flywheel to move may get it lined up and work. To me, it appears to be hitting something and not engaging like its supposed to. It is either not lined up and hitting the flywheel or something is wrong with the starter for being a new one. Try rocking the bike in gear and see if the teeth on the flywheel will line up with the starter drive.

I agree with others -- pull the starter and try it off the bike.
It looks like the solenoid is engaging to push it forward, but I see no spin and it shouldn't retract that fast if you are still holding the start button.

Pull it out again and test it.

Actually, it sounds like you have a wiring issue in the starter.

The start button activates the solenoid but starter does not spin.
The slam button sounds like its activating the starter, but not the solenoid.

Testing off bike is first step.

But before you pull it off, manually slide the starter drive forward and make sure it is not impacting anything and lines up with the gear on the clutch setup.

Where did you purchase the starter? After all you have done I would pull the primary to see what things look like, could be an alignment issue.
There were people selling starters on ebay that were having alignment problems a while back.

As the jack shaft goes out it does turn a little. It looks like the starter is not turning at all. I would test starter off the bike as stated before. Should pop out and spin as long as the start button is held.

I’ve never seen a good starter not spin or try to not be trying to spin with the start switch continuously pushed. It shouldn’t be only spinning for a split second. Either you don’t have a good ground connection (by good I mean clean with no corrosion and tight and no resistance). How do the attached wires look? Is there a corrosion buildup or maybe a breakdown when sending a high current through them? When you say this is a new starter, what about the connections to the battery? Are they the same as before? Are they clean metal to metal. If the slam button results in the same response, I would be looking at the actual starter wires themselves.

I purchased the starter from BDMs eBay store. The starter was removed from the bike and when hooked directly to the battery the starter spins. When I push the slam button the solenoid completes the circuit and also works as it should. When I attach everything to the bike and hit the start button the starter indeed does not spin but rather the jack shaft pops out. When this happens the headlight turns off and back on and the tach sweeps again, like the bike is turning off and back on.
