Are the valves on the 400HO/500HO hard to adjust??

 

Nope! Just pull the cam cover, pull the recoil until the cam sprocket index pin is dead center of the head and you can check the valve clearance. .006 intake and exhaust. If adjustment is needed,just loosen the 10 mm lock nut on the adjuster and turn it in or out until you have the correct clearance,then while holding the adjuster,tighten the lock nut.

 

Thanks. I do not have a recoil, do I bump the key to get it to line up??

 

Best on the "recoiless" machines to pull the plug,them bump the starter. May take several times to get it close. You can then grab the top of the sprocket with your fingers and turn it to TDC.

 

Fun to dig up some of these old post's and compare the thoughts, theories and guesses to what actually has taken place.
Turns out the 570 Sportsman is a home run, and already the 500 is becoming just a distant memory. The 400, 500, 550 and 800 are all a thing of the past. All replaced by one engine, the 570. With performance rivaling that of the 800, it turns out that there really is no need for something between the 570 and 850. Acceleration from 0 to close to 30 is nearly the same as the 850, about .2 seconds slower is all. Amazing amount of bottom end torque, which fits my riding to a tee. It appears that Polaris did their homework and knew exactly what they were doing.
After my wife sold her 500 and bought a new 2015 570 Touring EPS early this spring, I got to put in some seat time on it, including out on the slick rock of Moab. I was so impressed by it that after we got home, my 850 went away and was replaced by the identical twin to my wife's 570 Touring. Top end speed means absolutely nothing to me, so other than busting the trail through deep, heavy snow, I think I will not be missing my 850, and the associated issues that go along with it.

 

Yes the 570 is the engine of the future(hopefully unless it's replaced),but you'll still share the trails for years to come with the old Fugi engines for the sheer amount of machines sold over the years. The 500 alone had a remarkable 17 year run by itself and was dealers bread and butter machine. If the 570 can last that long and have as good of a track and production record,then people can look back and say the same thing about it. By the way,congrats on your good looking new machines.Hope you get many years of service from them.

 

The new 570 is probably the bargain of 4x4 atvs, from what I've seen anyway. More power than anything Honda makes and almost as much power as a Yamaha Grizzly 700 and costs a lot less. The Can Am Outlander 500L is about equal in performance but costs more. I've seen the Sportsman 570 priced as low as under $5000 for a base model without power steering, add a few hundred to get EPS. If I were to buy a new 4x4 utility, it would be near the top of the list.

 

I've had my 570 since March. Only been to one offroad park, and plowed with it once. Otherwise just riding it around the property with my son on his RZR 170.

The engine is strong...very strong. And I really like the AWD system. It goes REALLY well on muddy, rocky inclines. So far, I have no complaints about the driveline.

The rest of the ATV...well that's a different story. Fit and finish is the worst I've ever seen on an ATV of any pricepoint. It's worse than a lot of chinese quads I've seen. The battery is also in a horrendous location. The front driveshaft comes into the front diff at a 45 degree angle just to clear it. The thumb throttle is so far away that it cramps my hand to reach it...and I'm a tall guy. The "racks" aren't racks at all and are not nearly as useful as true ATV racks...though I do admit the front storage compartment is nice. The wheel offsets and sizing make it hard to find aftermarket wheels and tires without throwing off the track width of the machine. Service is expensive and the owners manual lists a different fluid for every part of the machine. After owning mine for a while and after reading through a lot of threads on various forums, I am not confident that this machine will stand up to the test of time.

I paid $4,861 out the door for my 570 but I could have bought a Honda Rancher EFI 4x4 for $150 more. I hope that I end up being wrong and this Polaris turns out to be a quality machine. If not, it'll get sold quick. I never had any trouble whatsoever out of my previous Honda or Arctic Cat machines and my son's RZR 170 is proving to be absolute junk so if this 570 follows that same path it'll find a new home.

But...the engine is stout. I'll give it that.

 

Like most all brands the small displacement machines are subcontracted and built by a Asian manufacturer.

Pay $150 more for smaller 24" tires and 20hp less power would be a odd direction of doing things.

 

See, I totally get what you are saying. People will forgive the rest of the machine for being what it is because of the Engine.

I like my 400HO, but my next machine will most likely be a King Quad. I'll pay a little extra for the Japanese quality. They are USA built too.
