Rough Idle or backfire on your Polaris Sportsman 600/700 ? Find out WHY!

[@BD-qq4fn]

Great intro! Thanks for another “problem solved” video….good info!

[@nbball44]

I saw you said the carb was installed incorrectly. Any vids on how to properly install a carb on a 04 sportsman 700? I think the one I just pulled was incorrect

[@TitaniummanGarage]

Not on a 700. But one breather tube on the right should be closed. The left open with a tube. The pulse pump gets connected to the engine. So if there is a port on the right to pulse pump it needs to be blocked off.

Got an o4 polaris 700 same issue. Put a new carb on and it's running really lean. Pops some and backfires. Not sure what I'm missing

[@wayne6525]

I have a 2008 Sportsman 500 ho. It ran fine when recently purchased. Then it started backfiring and would only stay running at high throttle. I discovered the rubber boot between the intake and carb had come loose from the carburetor. I reattached it and it ran fine until the boot came off again due to 😢the motors vibration. Looking into a replacement boot, I noticed a design difference. The current boot was straight in design. A new replacement boot it’s offset. I realize the carb and intake are not in alignment. I am hoping the new style boot corrects this issue.

[@TitaniummanGarage]

It should. Usually, a backfire will make the carb pop off if the inner seal on the boot it worn. Not sure what you mean that the new boot is offset. good luck.

[@andrewbratos6907]

do you have the 2 hole "air box foam seal"? GREAT VIDEO

[@thedominicanway9682]

I'm glad I found ur channel I got the same carb and I took the middle line off because it was making my motor cut off but my carb is leaking from the bottom and idk what else to do

[@TitaniummanGarage]

usually the needle and seat leak on them. Maybe try a different brand.

[@DmanDanstube]

Hey, I'm at a loss with my POS 700. Followed a bunch of your videos for ideas and I got frickin nothing still. My intake boot was ripped so now she idles better then ever, but original problem is I can't throttle past 3/8 of throttle I believe it's flooding out. I have replaced all fuel and air components ( fuel pump, lines, filter, carburetor different size jets in main and secondary new intake rubbers air filter - sparkplugs - checked the flywheel out i thought maybe she broke the woodruff key and is off time a little. That wasn't it. Disconnect the choke at full in. Pulled the primary clutch to prevent drag. Checked compression that was good. Hard to tell if I had a good seal on with the leak down test but it did pass both cylinders ( one cylinder at 9 percent one at 13 percent ) I'm looking for some fresh ideas. This is a 02 sportsman 700.

[@TitaniummanGarage]

Yup. I had the same headache. I cleaned my carb 3 times. Didn't work. Tried a aftermarket carb. Didn't work. jet was too small. I bought a 600 that came with an extra carb so I cleaned it, installed it and it ran perfectly. Check your fuel mixture screw. The only thing I can come up with is the carb needs to be dipped to clean everything out. Sorry I'm not more help.

[@DmanDanstube]

@@TitaniummanGarage thanks for the advice!!

[@redrider533]

Figure that 700 out. I have one with a brand to top end the will not take any throttle. Tried two cheapo carbs and they act the same way. Flywheel magnets are good an intact. Looks like it has an upgraded CDI set up since the old ones were problematic. Customers ATV and at my wits ends

Hey I got a player of 700 spitting and sputtering new new rectifier new stator new plugs new gas don't know what it is where where are you located

[@jasonruch3529]

Hey new subscriber here, Do those boots Rip because people don't put the metal brace back on? or because there is a metal brace? the engine floats on rubber mounts so it can actually tear the carb which is mounted hard on the frame, which is causing it? What's the best route? It's already got a new intake boot but no brace so I'm thinking it ripped and they thought it was due to the brace and left it off?

[@TitaniummanGarage]

Both..

[@braydenmeals9311]

Do you leave both carb ports open?

[@floydalebaby]

How would In contact with u

[@kevinhicks2818]

Where are you located?

[@moniquebaronette2250]

I have a 2004 POLARIS SPORTSMAN 600 when cold runs on one cylinder till it's warms up after ok

[@TitaniummanGarage]

They are cold blooded. Some guys use something to hold the throttle open till it warms up. But yeah. probably not good its running on one cylinder. Have you checked the plugs all?

[@WWG1WGA84]

Where do you like to get these carbs from? I got an 03 600 that needs one. Thanks

[@TitaniummanGarage]

Ebay. I look for the ones with a 10 year warranty on them. $38 bucks.

[@scottschrank4823]

Great video Lots of info

[@mikehodge1634]

Hey boss where you located I got a 700 sportsman to up and it is got code for 45 46 + 22 41 51 in northeast PA 2007 run like shit

[@TitaniummanGarage]

I'm in Wisconsin. I had a code on my 800 like that. I think it was 45 or 6. I wiggled the wires going to the sensor and it went away. Polaris had an issue with the thin wires going to fuel injection systems. Wires broke. Check those out.

[@mikehodge1634]

@@TitaniummanGarage can I just buy a new harness for that and the other question was with the fuel rail minds of 700 2007-2 up for the fuel injection rail I seen some with one line or two lines

@@mikehodge1634 LOL. If I had a dollar for everytime someone asked me to work on their sleds I'd be rich. I hate working on sleds. Not so much the engine. its synchronizing the carbs I'm not fond of.

[@Gamebit450]

what do you mean it wears out the grounds?

[@TitaniummanGarage]

They get corroded. Its a major problem with Polaris. I didn't explain it correctly.

[@nathancomerio6844]

Question. I feel like nobody has asked yet. Why does it sound like someone scribbling on a notepad after you talk. Btw love the videos, but i am curious.

[@TitaniummanGarage]

Haha. That's my camera zooming in and out. I need a mic to stop that noise from happening. Your not the only one that asked. Lol.

[@nathancomerio6844]
