2004 Yamaha Grizzly 660 Clean

Disconnected the plow yesterday on my 2004 Yamaha Grizzly 660 and am getting ready to do some riding yesterday and the battery went weak, Starter cranked a few times but week. Put my trickle charger on that I bought and went to the garage today to start it up, but the starter is just spinning and not engaging. The solenoid is clicking. The pull start sucks and is hard to pull (never use it and need to look into that). Quick video of the starter spinning. Could it be the starter or  the starter clutch one-way bearing? I guess I need to take the cover off to see what's going on.

Hi,
Have a 2005 grizzly 660. Just recently started backfiring and showing incorrect speed. Lifted seat and messed with wire going to starter relay, it stops for a bit but seems to come back.
I ended up pulling all the pins out of the connector for the relay and added new pin/connectors for all 4 wires. fixed it for a little bit but came back shortly after. This was a new starter relay i installed a few months ago. Anyone know if a bad starter relay would do this? 

Here are my 2004 Yamaha Grizzly photo albums if anyone is interested in checking out. 😎
 

Hi can someone please give me some sort of idea I have a Yamaha 600 grizzly four-wheel-drive I have put a new coil and a new stater and Pulse stater on it with new plug and steel can’t get any fire

not sure where to post this but,
 
I have a 2016 yamaha grizzly 700 with a blown up transmission (again).
 
I was wondering if a 2015 Yamaha grizzly 700 Main drive transmission shaft and gears shift drum will fit on my 2016?
