I have a 99 yamaha warrior and the start will spin and spin free and then after a little you can hear the starter slow down then it turns the motor and starts. this has been getting worse and worse I have no idea what can make it do this please help!

 

Check the starter gears for missing teeth, but the most likely cause is the one way starter clutch failing. It will be behind the flywheel, which will have to come off to fit a new one.

 

I wouldn't think it the gears because the start will just free sspin then slowly start grabing and then turns the motor thank you for the help

 

I would also check the battery voltage.

 

It's a brand new battery and even with batter charger on start engine it does it

 

When hooking jumper cables you to it it still does it I'm going to look for a short somewhere

 

I've had worn starter clutches slip and grab like this also.

 

I found some wires broken but it still ran and started so fixed them but still did it took the side cover off and see you have to have some kinda tool to the the fly wheel off but I should only be able to turn it clock wise right? All the gears are fine but I can turn the gears both ways

 

Then it is the starter clutch, and yes you need a puller for the flywheel.

 

Okay so I replaced the starter clutch and one way bearning helped but still spins for a little before spinning and when I took the old one off the bearning was locked up and stuck on the gear
