Well I pulled the motor apart and I did not like what I seen. Head dead Jim so idk if this motors even rebuildable at this point I gotta pull the clutch and get the motor split to see but it looks like it was run with no oil and the rod let loose taking the cam and jug with it.

 

Oh dude it's done. You could rebuild it but it's gonna get to at least 1100 bucks at minimum. I would send it in and get a motor from GTM.

 

I cannot take credit for that master piece lol I figured it would would about 12 to 1700 for mt to rebuild it myself but I'm worried the bearing surfaces are all messed up I didn't get the motor out to inspect it yet. I have no problem rebuilding it myself if it's salvageable but I don't think it is lol. I'll look into gtm I was looking at rev6 motors since they finance the motors and have a year warranty. Unless I happen to find a used motor somewhere.

 

GTM has a great warranty. I believe it's 2300 for a ready to drop in. That's what I'd do to. I bet it was the pressure relief dowel that fried the motor.

 

Looks similar to mine when I rebuilt. I ended up replacing pretty much everything internal.
Pay attention to that PRV dowel.

I put 2 5/16 ball bearings in there. It's been perfect. Pressures are at the book specs. I'll never put that dowel back in. My buddies just stick recently and fried the top end. That thing

 

I'll definitely inspect it well before I decide on fixing this one it may be a core lol

 

I did the small block Chevy head alignment dowel.

 

I don't trust any dowel after how bad my buddies and mine stuck in there. Bearings won't stick ever. It runs perfect I'm leaving it alone. Blew my buddies top end I got lucky and caught it in time.

 

From what I was told he was out riding it started knocking then stopped now judging by the 3 cases of empty twisted tea in the floor I assume that played a major roll in why it's dead lol. Plus when I checked the dip stick there's no oil in it. The ends of the balancer shaft from what I can see are blued from getting hot so it was lack of oil and maintenance they killed it. Atleast the head looks good lol.

 

I bet what killed it is the dowel stuck popped oil filter seal and drained all oil out and they sent it till it locked up. You'll never know if your oil filter seal blows and it's leaking oil then boom.

 

What is the prv dowel??? Sorry I'm super new to the rzrs

 

It's the Pressure relief dowel. It's the bolt above oil filter. Inside is a spring and dowel. It controls oil pressure to motor. Known to stick on the 800. It can burn up your motor. Many threads on it. Happened to me and my Buddy.

 

Oh thats good info thank you I'll look up what do to with it. I don't abuse my atvs so it will last me a long time but I'll definitely look into a mod for that. How do you tell if it's bad I assume you can't pull it out if it's siezed

 

When it's bad and sticks it will either starve your motor and burn it up or it will stick open and flood your lifters and shut it down. Never know what it will do and like i said it burned up my buddies and almost my motor. Put the 2 5/16 ball bearings in tested pressures for a month and took off gauge and sending it now with piece of mind. It's a crappy design flaw. Wait till you find out about the pinion nut. I just got done doing that and mine was one ride away from blowing up. Many threads on that as well. Worked out for me and was a little labor but not hard.

 

Well I pulled that plug quick to see if it was stuck and well its either not in there or stuck that bad that my 500lb magnet can't get it out I tried poking with a screw driver and using the magnet and nothing but the spring came out. So it's gone or super stuck my magnet is one of those 500lb magnet fishing magnets which I assumed should have pulled that sucker right out. So maybe that's why I blew up.

 

Yep if the magnet sticks to something in there than its that dowel. It's stuck. It's a bad flaw in the engine. The ball bearings work perfect. Screw that dowel. It could happen again on your rebuild or new engine. It's a flaw. Watch D Ray's shop pressure relief dowel on you tube. Great video. He saved my motor.

 

Remove plug & spring, hold rag over hole, and start engine, dowel may pop out.
May need to soak with carb cleaner or solvent.
BE READY TO STOP ENGINE AS SOON AS DOWEL POPS OUT, OR YOU WILL HAVE OIL EVERY WHERE.

I need help!!

I have a 2013 Polaris rzr 800s with around 2800 miles. My problem is when it gets to about 170 degrees it sounds like it runs on one cylinder. I have replaced the coil and spark plugs and still no difference. I have replaced the coil, plugs, and fuel pump so far. I need some help with what might...

His motor doesn't run dude

 

I knew that, but forgot. At this point, you can push it out from below, when the motor is torn apart.

 

Correct but still a pain.

 

That's probably what happened because there's no oil in the motor before I pulled it apart so that probably stuck and it pushed all the oil out the filter the dipstick was bone dry so im going to assume thats what happened. As far as using my magnet to get the dowel out my magnet didn't stick to anything there it only pulled the spring out I tried a small pocket screw driver with a magnet on it and nothing so its either stuck good or not there lol.

 

Crazy. Maybe they ran it without one. Will still starve motor of oil and burn it up but would not blow oil seal. Crazy man. Dude I bought a used one as well and holy crap I had to rebuild the whole freaking bike. People don't do simple maintenance on these things and cause a lot of issues. Make sure to clean throttle body real good as well.if the magnet doesn't stick then it's not there. Some people have punched them through into the motor trying to unstick them. Hard to say man.

 

I even snorkeled mine due to the shitty stock location of air breather. Its under the bed sucking nothing but dust all the time. Welcome to having an 800. Great powerful machine but a lot of bugs to work out.

 

I was thinking of running a snorkel just due to the location of it. For 1000 bucks even if I put 2k into it im still happy it has brand new super atv 5 inch lift rhino 2.0 axles all around it has a ton of money put into it so it will be an amazing machine wants its running again.

 

Oh hell yea you'll love it. Damn I wish mine had some rhinos on it so I could lift it that high. It's a solid machine.

 

From what I seen there's about 3 to 4k in parts the exhaust wheels and tires the lift and axles alone. So I'm happy I got it so cheap and the orange paint sold me I have a orange blast srt4 so it's perfect lol. I recently got a 99 scrambler 500 4x4 for 300 bucks and I love it the. I seen this and couldn't pass it up. I'm gonna go buy 2 ball bearings for when I get a new motor or rebuild this one.

 

Great deal. Good luck getting it going. It's got duel exhausts? Why? Is it turbo?

 

No turbo it's hmf but no idea what kit but I like it lmao no idea what it sounds like yet but I'll find a motor soon. I'm super excited to get it going gonna do alot of research on what should be done to it. I do have all new diff and trans fluid for it and all new brakes that came with it. Oh I found the exhaust that's on it im pretty sure this is it. HMF Performance Exhaust Pipe Dual Slip On Polaris RZR800 RZR 08 09 10 | eBay

Those aftermarket are super loud. Some like it but it is silly loud. Still awesome machine.

 

I'll see how it is when I get her going I'll probably swap it out. I'm only 30 but I don't really care for super loud exhaust on my offroad toys. Although I have a big block impala with 3 inch side pipes lmao

 

Lol

 

I also noticed it has a power commander installed on it as well I keep finding more toys on it lol even has a 500 watt blue tooth stereo. And yeah I just dropped a 396 big block into my 1970 impala now that projects finished up I can move onto the rzr that's my pride and joy. But I have like 3 other cars to lmao im a mechanic for a living and have a problem buying cars

 

Awesome man. Only a thousand bucks wow! Guy could have parted it out and made a killing.

 

Well ill probably keep this thing forever I still have my very first quad i bought when I was 16 lol a 97 warrior I still ride it from time to time. My brother rides it now when we go out riding so I can't wait to get this things going. I bought it more for my mom anyway she had a bad atv accident last year broke 9 ribs collapse lung broken collar bone she was pretty banged up so when I found this and for the price I couldn't say no ill definitely enjoy it and atleast she can drive it as well when we go out. I have plenty to ride lol rm250 400ex bored 440 with stage 2 hot cam the 97 warrior and a scrambler 500 4x4.

 

Sweet dude.

 

I would make some kind of heat shields if you keep those aftermarkets on there. RZR 800s are known to have fires and had recalls that they put heat shields on to remedy. Just a heads up.

 

I'm looking into options for the rzr If the cases are OK I found a kit with cam and high compression wiesco pistons for 1800 so not sure what I wanna do a remand with a warranty would be nice for sure

 

Sky's the limit man. If you want to get bigger pistons and jug go for it. It all depends on how heavy of tires you want to run and how you want to ride. Then you'll have to do clutch upgrades etc. If it were me i would get a drop in motor. On a burned up rebuild like that God only knows what you'll have to replace in it and when you fire it back up will it run. A place like GTM with warranty is the way to go in my opinion. It's not like it was just a crank bearing or a top end. That is a locked up God knows what's wrong nightmare. I've read of too many people's rebuilds costing a thousand dollars more than a complete refurbished one with warranty.

 

True that right now it has an upgraded clutch kit as well running 27 11 r14s on it now I'll most likely stick with this size tire. I'd love to rebuild it myself but if the internals are all burned up I'd rather get a motor with a warranty

 

Dude i would of driven across country for that deal. Up here in Illinois I paid 8k for mine last year but sold 2 quads so really i only paid 2k for mine but up here they hold their value. I got ripped of as well cause it was beat the hell up. I would have to drive to southern Tennessee or farther to get a good deal. Yours is decked out. Unreal how someone puts so much money into it and basically gives it away cause they blew the motor. Wow. Mine runs and rides tits now but I way overpaid.

 

Yeah it has a ton of aftermarket parts I even got the clean title with it. I'm trying to find a place that would maybe finance a motor for it. I keep searching but nothing local. I'm hoping when I get my clutch tool tomorrow and I pull the motor out and apart that it's rebuildable I don't mind building it I'm my own warranty lol I'm determined and impatient lol I wanna get it running as soon as I can.

 

Oh I feel you man. I don't care if I had to take out a loan a new motor would already be on the way. Welcome to the money pit addiction lol.

 

Lmfao I'm working on a loan or something I wanna get it done

 

I feel ya man. I'm taking her out tomorrow. Snorkels to the roof and ready to send it.

 

Maybe it's just your crank and bearings on the bottom end. Top end is only 275 bucks with new jug,pistons,rings,seals etc. You would have to buy new rods but they should come with a crank kit. Like I said 1200 bucks at minimum.

 

I'm worried about the case because how bad the rod was broken it snapped the cam on 4 places and it was run low on oil so I need to thoroughly inspect the case and cam bearings and everything to make sure I'm able to build it. I have no problem building myself and would honestly feel more comfortable knowing I built it lol. If it's salvageable I'll find out tomorrow this is the kit I found I feel this is everything I need to build my motor if the case isn't wrecked. What do you guys think of this kit???
