96 Polaris xplorer 300 issues

I'm new to this site so this is my first post. I bought a 1996 Polaris explorer 300 4x4 since I moved from the city to the country and I wanted an ATV to do yard work. Two years later I bought a new ATV and want to sell the explorer but it got some issues I want to fix before I put it up for sale. I'll be riding around and after about 15 mins of riding and warming it up ill give it full throttle down a straight road and it will bog down and die, I will try to start it and it won't start I have little mechanical experience with these machines so I have no clue as to what's happening

P0301 Engine Misfire

Hi everyone, I am having an issue that is getting really annoying and I am unable to locate the problem. I am really hoping someone in this community can help!! I have a 2015 Can Am Commander 1000 XTP. It currently has little over 16000KM of pretty much flawless miles and I love the machine. A little while ago upon starting my machine and idling to warm up, I heard a change in note and the engine was obviously running rough and on one cylinder. It went into limp mode and provided a engine misfire code P0301 indicating it was cylinder number 1. I initially just turned it off and upon restarting it worked fine and code was gone. Thought it was a one off... a week later same issue which was again resolved by just shutting off and restarting and the rest of the day was fine. It continued to do this and became a little worse over time doing it every cold startup and disappearing when engine was warm. I was preparing machine for a long trip and had dealer complete a few maintenance items including changing the spark plugs believing one may have been fouled a little causing the issue. The plugs with 15000km on them were in great shape and probably didn't need to be changed. The issue didn't happen at first at the dealer but before I took it they did finally see the issue and while hooked up to computer verified it was misfiring. They felt it might be a dirty injector and suggested I try some cleaner in my fuel. So I was beginning a 1200km 7 day trip and during same I used the best fuel I could find and did use a injector treatment (seafoam). The issue seemed a little better at first however it was still present. By the end of the trip however even with engine warm when I let it idle it would go into a misfire and limp mode. Re-starting still resets it and if I get on the gas I can still go all day!

So I decided its time to fix this for good... I tore everything down and first took out both injectors and the cylinder #1 injector did look a little dirty so I thought bingo... To be sure I cleaned them and swapped them so if issue was the injector it should now be cylinder 2. Nope still have problem and its still number 1. So Injectors crossed off list. Next thinking coil. I swapped out coil from identical commander (friends) and still no change. Swapped out coil wire to #1 still no change so not coil or wires. Had a fuel pump pressure gauge and checked pressure. Seems perfect with the pressure holding strong even when the engine dying down with misfire and not to mention issue never changed to any other cylinder except #1 so I am confident that fuel pump is ok. Next I am going to have a look at the air intake with throttle body etc as I did notice it was a little more dirty then I would like when I removed the injectors and could see behind towards the air filter. Thought about valve issues maybe but there is no sound and with the plugs being in great shape think they are ok?? After I try everything else I can I will get dealer to look valves over if necessary.

So question......... anyone out there have anything similar or any suggestions for me. Very annoying problem that needs to be resolved.

Thanks

Looking for 2nd Sportsman

Hey all...

Recently bought my 1st ATV. Its a 2015 Sportsman 570 EPS.. Love it! Looking for a 2nd for my girlfriend to ride. Not finding another 2015 thats got EPS and not abused.. I am finding several 2014s.. Were there any improvements on the 2015s? My thought was to get 2 the same year model so experience fixing, parts etc would be the same..

Knocked out high beam light

2012 outlander 1000
A big Branch pushed the high beam light and broke the ear tabs
I used special plastic epoxy with primer and it worked for a few rides now it's broken again what's the best way to fix this issue?
Thank you for all your help

I am new to Can Am but not to ATV's.
Since a kid I have been taught to check the oil cold. My Outlanders owners manual says to check cold. The dealer Techs tell me to check it warm. After an 100 hr service I got back home and found the oil level an inch or more above the max mark. I took it back and complained about an over fill. The tech went out ran my machine a bit shut it down and rechecked the oil and it was at the top of the max mark. What is the straight procedure. I would think the owners manual ?
