Broken brake discs

Hi. I have a 2010 Sportsman 500 ho, with 2500 miles of use.
Checking the condition of the brakes, I found that the brake discs (rotors) were completely damaged.

The rear disc is the one that had the worst damage

Anyone know what could be the reason for this?

2014 trx420fm wont start

ok so this atv cranks but will not start.
It starts with starting fluid, and is getting fuel to the injector. I have power at the injector but will not spray any fuel, it is a new injector as well.
not sure what else to check.
someone please help.

I also put jumper wires to the injector from battery and it sprayed fuel, but not with it connected right.

2015 rubicon wont restart

I got a 2015 rubicon with a hmf performer pipe and tuner that eliminates the o2 senser. the quad will start and run fine but won’t restart once turned off by the key but did restart when using kill switch. Quad will start after it sits for a bit. It gets gas and spark Just won’t run. Quad did have a run in with some water but it ran fine that day and the next day but a week later I have this problem

400ex clutch issue

So I resolved the smoking issue with the Honda dealer. 500$ later there’s no smoke but now my clutch is broken?

I’m including a video but basically it feels like the clutch is always engaged (as if the lever isn’t pulled)

When I adjusted it as much as I could (including barrel extenders from asv)

It still won’t "disengage", and was extremely difficult to pull in.

In a fit I just removed the cable from the lever down by the tranny and found that the lever isn’t where is used to be. Now it swivels to a 90 degree with the tranny. As if it won’t catch on to disengage the clutch.

Including video.
