I have a 2016 570 EFI that isn't starting correctly. Over time it has gotten where it wouldn't engage and start. Sometimes it would start and other times it wouldn't. I have taken the starter off and the gears look OK. I have watched You Tube on how to change this so I then went inside and checked the gears on the inside and they all look good. No signs of gear damage or shavings. I have also replaced the battery. I'm thinking the starter is not staying locked in while starting the engine. Can anyone give me experienced info on this matter.
Thanks

Most likely the starter solenoid is not "kicking out" to engage the flywheel. When it does not start does the starter spin? if so good time to invest in a new starter or, if you can pull it apart you might be able to see what the hang up is. Possibly bad / worn out bushing or bearing, gummed up internal solenoid lever linkage or sliding gear.

Anatomy of a starter

These engines don't have a starter with a bendix like a car starter, they are just a motor with a gear that spins a gear set connected to the flywheel with a one-way bearing on the flywheel. The starter gets it spinning and then when the engine fires and takes off it overdrives the one-way bearing allowing the starter gears to disengage.

OP, you're going to have to be more detailed in what the starting issue is. I can't tell by your description if you need to be looking at the one-way bearing (mechanical issue) or the starter motor/system (electrical issue).

Thanks for the information this helps. The starter will spin but will not stay engaged. Sounds like the old starter bendix of past not staying engaged and having striped gears. I had about decided it was the starter or starter solenoid. Question where do most of you buy your parts?

Call dealer to get price, then check SuperATV, Amazon, eBay, Google search for aftermarket or OEM.

That definitely sounds like a one-way bearing failure. It's behind the flywheel so you'll need a flywheel puller, as well as oil and filter change and coolant. I'd probably start with a service manual so you can see what's involved and go from there.

For OEM I usually look it up on RMATV for the part number and then do a search. Also usually call the local dealer to see if they have it in stock or can match pricing (this is also a great way to find discontinued parts sometimes).
