Hey Everybody,
I am always curious about any ATVs I haven't tried yet. I'll probably be in the market for something different soon, currently looking to sell my 05 Brute Force 750. I decided to note my favorite features of any 4x4 ATV and compile them into a list. These are all models I've had in the past, the King Quad 300 and Brute Force 750 are my current models. I'll most likely consolidate to one.
Really just wanted to get some ideas on what other people have owned in a similar range, and maybe get ideas for my idea quad (used). So far, I keep finding myself back at the 05 Yamaha Kodiak 450 or Grizzly 450. Not sure exactly what years they made which, but they seem pretty similar.
Some of the features I tend to like best (aside from durability and reliability)
Engine braking (good for hill descent) Park gear (the regular parking brakes always seem to be finicky) Mid sized engine for better fuel efficiency (Seems that anything 500 or above really starts to guzzle gas, and they fit better on narrower trails) IRS (more comfortable ride) Diff Lock (can't live without it) **Side note: I know Durability and Reliability might seem like they'd be the same, but the way I am defining them is:
Durability is how long I can go without something breaking. OR how often things break with seeming not much of a good reason. Reliability is about the on-trail experience of having everything work properly as designed (i.e. Starting up and being able to get going without much issue, the 4wd drive engages without quirks, I can park it on a hill when needing to help someone else without worrying it'll roll away, etc) My Brute Force 750 is a perfect example of why Durability and Reliability were rated so differently. With durability, I really never felt like I've had anything break on the thing that was really from riding it. Which is great in that regard. But all of the things i've had to fix on it seem more so in it's design. The infamous KEBC code on the dash that refused to go away even after completely cleaning and lubing the KEBC and confirming it functions properly. Hard starting issues. 4WD requires you to roll about 10 to 15 feet to engage, so if you get stuck in 2WD, you're in a pickle. The infamous bus connector that goes bad and stops your charging system from working. I've worked through all of these, but these are all things I'd consider reliability issues that happen really at no fault of mine as I ride it pretty gently. Writing up this list has actually put a lot into perspective for me. The King Quad 300 really is a superb quad. The inclusion of the Super Low range provides stellar engine braking down pretty much any hill you can think of, it seems like it's unmatched. It has great gas mileage, and it's been dead reliable despite being a 1994. It's got 4x4 AND Diff lock, and the semi automatic transmission also help with not letting the quad get out of control down a hill. Plus it's more fun to me and gives me a bit more to do while riding. The biggest annoyance so far has been the parking brake. No matter how much I adjust it, it just doesn't seem stay adjusted after some time. I believe this might just be flawed on these models. Also, parts availability is not the greatest on these since they don't make anything newer with any similar parts. Front axles are quite expensive, rear drive shafts go for $400 to $500 brand new, etc.
And that's where the Park gear on Yamaha's Ultramatic eliminates that issue. That's where I keep landing on the older Grizzly or Kodiak 450s. They have a park gear, IRS and Diff lock, a lot of power and they're super fun to ride (got to test one). But I'd be giving up fuel efficiency and the Super Low range. The Ultramatics still have good engine braking, but still not comparable to the Super Low on Suzuki.
With ALL that said, curious about what other people out there have had and enjoyed, and I'm just looking to get some ideas of what other smaller/mid sized quads are out there with similar features. I don't really know anything about Honda, Suzuki, or Arctic Cat models from the mid 2000's.
Curious to hear other perspectives!

Hey everyone,
I’m having an issue with my 2021 Polaris Sportsman 570 – the engine keeps stalling after running for about 10–15 minutes. I’ve checked the air filter, spark plug, and fuel lines, but can’t seem to find the root of the problem. It starts up just fine, but then loses power suddenly.
Has anyone experienced a similar issue with this model/year? Would appreciate any advice or troubleshooting tips you’ve tried that worked. Thanks in advance for your help!

This thing came with a cheap aftermarket carb on it the problem I'm having is it won't start with choke installed into carburetor it will start and get run without it installed then bogs out after about 2 min run time I've checked timing , compression, checked valves for proper clearance , also did a smoke test for air leaks found none.

Hey all, new to the forum! I just bought a 1998 Kawasaki bayou 300, 4x4 not running. Initially I found no spark. Ended up playing with the plug wire (made sure plug top and wiring was touching) and got spark yesterday and the quad fired up off ether. Come to work on it today and now no spark again. Before I got spark and now today if I touch the plug after cranking I get shocked, and it will spark after I release the starter button. I was jumping the quad with a freshly charged car battery that has 12v while cranking. Cleaned out the kill switch and ignition button. All looks good. Purchased new plugs. They're are a lot of wires cut/ disconnected. But shouldn't matter if I got spark without them connected...
