Don’t Know what happened

Hi everyone I am new to the atv world. I bought a 2014 sportsman 570 eps the other day. It was used in winter to plow and stored the rest of the year. It had 45 miles and 2 hours. I was riding around the block as I heard a few loud pops and stalled, and then it wouldn’t start back up? Any idea on what the problem could be. Yes it had gas and oil. Thank you I’m advance.

My Polaris Sportsman 500 Big Boss nearly killed me this morning.

Throttle stuck wide open. Label on throttle control states ". . . this machine equipped with ETC, Electronic Throttle control, to PREVENT stuck throttle situations"

Uh, yeah, right! Wiped out my wife's flower bed and hit a tree at full throttle 30 minutes ago with brakes on full and wheel sideways trying to avoid. . . had to turn off key switch to stop. Now it is running WOT at IDLE even. What a . . . expletive removed but there were lots!

Some symptoms:
-- lately it has acted up a bit by going to high throttle and then self-reducing back to normal so I have opened up the throttle control and see nothing wrong, spring and cable seem to be working normally. This has happened at random and only a bout 5% of time in use.
-- noticed smoke coming from a white wire up front on left where a bundle of wires enter a little black box behind radiator, out in open fastened to a bracket holding the back of radiator. Smoked stopped quickly. Seems like the timing may correlate with start of these problems or soon thereafter.

WHAT is that little black box? about 4x3" x 3/4" thick. see photo.

Why would a wire be SMOKING? Aren't there fuses to prevent stuff like that?

Dealer not open yet today but I would appreciate some input on this. Could it be the ETC system is that black box and is that the thing actually causing the problem, ironically, since it is supposed to actually PREVENT this?! Unreal.

Tube valve stem type

Hi
First time posting...


I've searched what I think are the correct forums for over an hour looking for an answer, but have come up empty.


I have a 2008 Outlander Max 650. Today I put a hole in the sidewall of my rear tire (tire found a partial power saw file) ..... I patched it but am not confident that it'll hold so I'm looking to put a tube to ensure no leaks.


Tire size 26 x 10 x 12


Does anyone know what type of valve stem is required?
It'll be either a TR6 (straight stem) or a JS2 (right angled stem) or ..........?


And, if anyone has a link to an online retailer with the appropriate tube noted, I'd appreciate the response.
I live in the boondocks so mail order or UPS/FedEx is my only option.


Thanks in advance for any thoughts/comments anyone has to offer.


Cheers, Chuck

Need to grease wheel bearings?

I am replacing my front wheel bearings on my 2008 Polaris Sportsman 300, They look like sealed bearings
that don't get greased. Am I wrong, is their a way to add grease? Thanks in advance for the input.
