Ok I'm absolutley stumped and I'm in need of some ideas or assistance. Im working on a fourwheeler for a buddy. It's a 2016 Honda Rancher 420. The problem is the bike will not start. When you hit the start button you can hear gears turning over on the back side of the engine. First thought (since he already replaced the starter) the one way starter clutch. I tore the bike down and got to the reduction gear and the starter clutch. The clutch free spins one way, then it locks the other way as it should. I took a flat head screw driver and wedged it to put pressure on the gear to see if it would slip, and it didn't! I doubled checked the reduction gear and the starter output shaft and everything looks great! Could it still be he starter clutch? Or could he have ordered the wrong starter? Maybe new starter is bad? I'm stumped!
Help!!!

I would pull the starter and verify everything is working properly, ie., starter solenoid, etc.
Everything works as it should when you hit the start switch. Just not turning the bike over, very weird gringing/ slipping noise. The starter is turning clockwise the way it's suppose too. Also the bike has never been torn down so the starter clutch is in the correct way.

Need a pic to verify its reassembled correctly. Also did you verify the timing chain is ok when you had the front cover off? If timing chain is ok and there is a grinding noise then remove the back cover and inspect the starter gear against the fly wheel.
You should be able to stick your finger in the hole and turn the starter gear to the right not the left.

and which way did the old starter turn ?. you can do what was said to check which way the starter transfer gears are suppose to turn to lock the flywheel by putting your finger just inside where the starter goes in, spin the gear, see which way it free spins ?, and then go the other way, and see if it locks the flywheel ?, odds are, the starter is not turning the correct way would be my guess.
Cover is off and the starter clutch is working properly. I wedged a screwdriver to lock the starter gear and turned the crankshaft to see if I could get the one way starter gear to slip. It didn't budge. Turned the gear counter clockwise and spins freely. So it seems to me the one way starter clutch is ok.

Go to where you reply, then drag the files over to the box that says "drag files here to attach" if your doing it on a phone I have no idea.

which ever way your flywheel locks ?, your starter has to spin the other way.

The starter gear works like this. The gear should easily turn clockwise (right) but not to the left unless you have a REALY strong finger lol

The engine runs clockwise once it's started correct? You have 3 gears, starter gear, reduction gear, then flywheel starter clutch which is behind the flywheel. The starter itself when powered with 12v turns clockwise. Which then turns the reduction gear counter clock wise, then that means the flywheel starter clutch turns clockwise. If I turn the starter clutch gear counter clock wise it free spins. If I try to turn it clockwise it grabs the crankshaft and turns the engine over. This is why I don't think the start clutch is failing.

it doesn't make much noise even if it were turning backwards. We need to know where the noise is coming from.
Is it coming from the starter or can you turn the starter gear with your finger and it makes noise? Or can you move the starter gear with your at all?
