Block full of gas running out in air filter box

So my buddy swamped my brand new 850 Touring SP with only 7.6 hours on it lol and the engine is toast. I’m going to be putting a 2018 1000 engine in it because I got a good price on a used one. I’ve been cross referencing part numbers for days to make sure everything will fit but I have a couple questions.....

Does anyone know:

1. Can I re use my 850 exhaust pipes? I can’t find any info on the exhaust port sizes of the 850 vs 1000.

2. Can my 850 ECU be reprogrammed to run the 1000 since they both use the same ECU?

Any help would be appreciated.

THANKS!

hi guys new to the forum having serious problem with my sportsman first start of the day never mind what temperature it is very hard start and sometimes backfires and pops through Airbox. once it starts after 3 minutes of turning engine it cuts out on idle then i start again and runs for couple of seconds and cuts out and I keep trying and eventually stays running for longer maybe 3 to 4 mins on idle and cuts out again but really the hotter the engine gets the better it starts and runs on idle. but if you floor the throttle when it's running after getting it going it cuts out or splutters. I have a couple of videos taking off how it running and will do a cold start video tomorrow. any help greatly appreciated this bike has very little work done and hasn't being worked the last 2 years because nobody including Polaris dealer cant find the problem I fix a good few quad bikes myself but never Efi all carburated machines. so far the ecm has being changed throttle body fuel pump fuel filter spark plug and lead I also repaired wiring on engine temp sensor also. but the first time this bike came in to me and hasn't left 😤 but first thing I checked was spark and fuel was getting fuel but no spark changed the plug lead and got spark then changing this then we go back the long cranking untill it finally fires up and cuts out whenever it feels like it but runs alot longer when hot but still you hear the odd pop like it's going to shut off . it has fresh clean fuel all of the times iv tried it but also when I was changing the fuel pump which looked fine would I better to change the fuel pressure regulator. thanks in advance for help provided��

I need some assistance working on Polaris 850 2019 model. I installed a new crank and main inserts. I've timed counter balance shafts but when I install the bottom half of the case it has a gap. Any suggestions?

I believe I have a bad TPS sensor in my newly acquired 09 sportsman 800 efi. I have a few new tps sensors coming in from China and I'm sure they are going to be garbage. I noticed someone local to me selling a throttle body with the sensor included but he wants over $100 for it. I'm reluctant but I would rather have a Polaris part then the ones I've order from China.
Is there a way to test it with a meter and a nine volt battery before I hand over the money?

I am interested to know if you've had success with a particular cooler strapped to your racks. Yesterday, the cooler we had strapped to the 570's racks broke apart. It was completely filled with ice and gatorades. After it broke, the bungees did little to keep it in place. It fell to the trail, spilling all of the ice. We called it a day at that point... it was too hot to continue without the benefit of cold drinks.

Anyway, I'm looking for a sturdy cooler. One that will hold up when filled, and take a bit of jarring while strapped to atv racks. I really need it to work... I do not want to spend big money and it end up breaking. Thanks for your input.

Hi. I’m not having luck. I know this is a poliars site but I got a 92 bayou atv. Was out ridding and it shut off like I hit the kill switch. Wait 5 min and go agin. Doing that for a day and finally it quit and I check fire and no fire. Put a new CD I unit on and it never worked. Put a old cdi unit on and it ran fine for three days. Then agin the same. Then it lost fire agin and I took the new cdi unit and try it to see and it worked. Weird. But the bike starts and shuts off. Then starts and shuts off. Then if you hold the trottle a bit it will stay running. When it warms up it will idol fine until u put it in gear. Then it shuts off. But it will start right up agin. If you give it trottle while putting it in gear it will go and run fine as long as you don’t let idol. But some times like within 10 min it will just die like I hit the kill switch. But give it a little fuel and it will go agin and ride a few minents then it shuts off and start right up and gotta give it trottle to go when us put it in gear. Please please please help. I ordered new cdi agin and coil. What can this be cause it’s weird.
