2018 Sportsman 450 HO Won’t Start

I have a 2018 Sportsman 450 HO. It has less than 15 hours on it. I was plowing snow yesterday and it died on me. It restarted and ran for about 10 seconds and died and sounded like it backfired. I waited a couple of minutes and restarted it. It ran for about 3 minutes roughly and shut off. I pushed it back into the basement and pushed it out this morning to try to start it again. It ran for about 2 minutes roughly and shut off. It would not restart (engine turned). I pushed it back into the basement and checked the spark. The plug (Autolite) looked good and had spark when I grounded it to the engine casing and turned the key. I am using 87 octane gas with Ethanol. Should I drain the gas and try non ethanol or take it back to the dealer since it is still under warranty.

Rear diff noise & Excessive play on yoke

Hey guys . Noticed a rear Diff noise in my 2016 outty xmr 650. It has 500 miles. Drained it, and the fluid looked horrible- thick black full of fine metal shavings. Lots of play in the yoke and axles. Then after doing some research come to find that they are notorious of this. Have yet to pull it apart and inspect. But I’m wondering what the best fix is. Should I Rebuild the stock diff, buy aftermarket, get a xmr 850 diff etc. I’m assuming the drive shaft is outta phase as well causeing this whole problem. And wondering about where to buy a new shaft or getting mine reworked etc. I’m so pissed off that can a.m. would manufacture such garage. I bought this thing because I felt like the quality is so much better but am really starting to wonder. Also it has that can a.m. clunk coming from the clutch is there anyway to fix that ? It’s pretty embarrassing, and does it every time you goose the throttle.

Another new guy with an old Trail Boss 400 4X4

Hi folks .. from London, Ontario.

Playing with my new (to me) 1994 Trail Boss 400 4x4.
I had issues with reverse but fab'd up a helper leaver to my reverse linkage on top of the tranny. Bit of a nuisance but works.
Then started to do the wiring fix for faulty front wheel drive but checked the hubs first and keys on both axles were sheered ($6 for a bar of the stuff.. fixed).

Now... I don't want to ride it until I identify the centre light being on all the time (idiot light bezel missing), just in case it has something to do with the oiling system.


Does anyone have the same machine that can help a guy out? (see pic)
I've marked the two lights I know just by shifting.

Thanks in advance. I'll have a proper manual before too long, but was hoping to solve this sooner.

Cheers All..

Primary spring retainer cup stuck?

So I replaced the slider pads in my primary the other day, and that went well, no real problems there, quieted down real nice, a whole lotta "clackalackalacka" I had been tolerating.

But I've apparently noticed something that may or may not be cause for concern, wanted to throw it out and see:

When I pulled the outer sheave off, there was no "spring-loaded tension" to watch out for, as it appears my retainer cup was stuck/seized in the barrel there, the outer sheave came off in literally "one" piece.

TBH, I didn't even know at the time that there was anything "wrong", I've only started to pickup on it now that I've been youtube-ing clutch kits and spring swaps. All those vids show the outer sheave on the primary being "pushed" out by the spring force, upon disassembly.

I've (un)fortunately already reassembled everything with the new belt, so I'm not in any hurry to tear back into it, and as far as I can think, I don't reeeeeaaaally need to, right? I mean, once the clutch bolt is torqued back down, that retainer cup is going to bottom against the one-way anyway, and the spring would behave like it should, I'd imagine.

Anyone got any insight to the contrary? There's no retainer clip or anything, in the partsbook, that would explain why my cup came off with the outer, it must've just rusted/seized in there from over the years.

LED bulb

Hi everyone! I’m thinking about switching to LED headlight bulbs and I’m looking for some reviews from you all on brands. I have a ‘09 and I think they are H4 bulbs. Do any of you have trouble with the cooling fans on the bulbs getting mudded up? I like Nineo brand on Amazon. They have great reviews.

Sportsman 700 Troubles

My problem is complicated so please bear with me. My 2004 Sportsman 700 was leaking fuel out of the carburetor overflow tube every time the throttle was pressed. There was no tube off the carburetor so it was dripping right onto the engine. Eventually it ignited and caused a small fire that was quickly put out. Once it cooled off, it started right back up and ran fine the rest of the day.

I only had to replace the choke cable after the fire. Everything else seemed fine. Next two times I took it out, it would run fine for 100 yards then it would die out with throttle and backfire. Taking your thumb off the throttle, it would go back to idle without stalling out. I limped along like that for about 20 minutes. Let it sit for about 15 minuets. It started back up and ran fine the rest of the day.

Something else must be damaged, but I don’t know where to start. Any advice appreciated.
