I just recently purchased a Polaris xpress 300 and have had a number of problems.. I purchased it in none running condition and found that it needed a top end done.. after completing the top end and not being able to find the oil drain plug for the engine, any kind of dip stick to check the oil, or any where that I could fill the engine with oil I was already frustated enough.. and then when i finally did get it started and tried to put it in gear and it would just grind(no matter what gear) My frustation has become monumental.. any help with this problem would be greatly appreciated.. i've already tried to idle the engine down to it nearly stauling out and then tried putting it in gear and it would just grind, or if i tried to force it it would just staul out completely.. for fear of tearing up gears I would like some input procede any further..

So it's been a while since I was on here begging for knowledge but....here I am again, like a bad penny.
So my 300 bayou was fine and I drive it close to 30 miles a day ( no joke, no license). I pulled over to light a cigar and drove 100 ft and started down a dip in the dirt road and it acted like it was out of gas (just filled the tank) but then when I tapped the brakes it started running fine.
Now it'll start but runs rough unless I turn on the headlights and brake light them it'll even out and at first it'll skip and backfire almost them it'll run fine untill it goes to idle them repeat above. If I sh** off the headlights it wants to die. My boss has the same 300 so I swapped battery and cdi and regulator with his and still the same jazz. Could it be the coil? Don't they do like old cars and just die? Also went I throw my voltmeter on the battery while it's running it sits at 9.87-.99 like it's not charging, did that even with different battery, reg., Cdi. Checked the grounds, all good. It's always been a rule that if a battery has only 9 volts then turning on the lights drains power and it runs worse. I'm confused like I just saw a churchmouse kick a barn cats butt

Hi bought a 2012 kingquad ASI last year a great machine which is a delight to ride, but I find sometimes it doesn’t go into top gear just revs high at about 42mph. Any idea ???

Well, after tinkering on my last project (a 2003 Kawasaki Bayou 300) I ended up putting it on Craigslist and it sold within a day. Then about two weeks after that a 2005 Mule 610 with 40 hours on it popped up, for about 1/3 the cost I usually see them, so... I didn't have much of a choice.
The Mule's first issue was idle, it would die if you didn't keep a light toe on the accelerator. Turns out the idle screw had never been touched, five minutes after I got it off the trailer it idles just fine. 🤦♂️
As of today, it runs great on flat land. And it climbs like, well, a mule.
But it has one issue. Sometimes uphill it will suddenly lose power like the fuel isn't getting delivered. It never dies completely, it just sputters and won't go until you let off the gas pedal and let it recover. It tends to do it more with 2 passengers or some cargo and wide open throttle BUT occasionally will do it at only partial throttle and with just me on it.
I read a lot about how the fuel pumps on these Mule 610's suck, so I put in a new one today and a new fuel filter. It still had the same symptoms immediately after, so that was $40 wasted.
Any ideas? I keep seeing folks saying they replaced the pulse pump with an electric fuel pump. This thread said so, and it gets brought up in this thread and also here. In each case somebody says "12v fuel pump solved my problem!" and then they promptly disappear from ever posting again, lol.
I have some questions for y'all:
1. Do you think fuel delivery is the problem? I have a hunch that it is, given the hill + throttle symptoms.
2. The pulse pump on the Mule is located ABOVE the gas tank. Can an electric fuel pump pull fuel UP in this manner?
3. What would I do with the spare line that goes from the fuel pump to the crankcase? Every electrical pump is just in & out, they don't have that third line...
4. Any idea what kind of flow rate I would need or which pump works for this application?

I was out riding my loncin hunter 250 yesterday when i thought i'd go through a mud hole but it did not liie that and after that it started running bad but still ran all the way home, i shut it off for the night and when i was going to start it this morning it would not fire unless i had full throttle and even then it ran bad with a lot of white smoke. Does anybody have any idea if it can be fixed or if i might as well buy a new quad
