Hello. Here is my 570 and we will progress thru the build together as I get the upgraded/added parts.

Before Mods

First thing I added was a Snorkel kit from SnorkelYourAtv. Out of all the options out there I really liked the new drilling in the airbox aspect this kit offered. I used more silicon then they instructed also really dig the risers vs the usuall plumbing pvc types.

Hard to tell in these images but I drilled the holes a tad to close to each other and the risers touch awkwardly. 131 dollar mistake I will correct by getting a new front storage lid for redrilling(next year).

Installing KFI Winch this weekend and A Arm armor by Ricochet. More pics to come.

I’m no spring chicken and my 7 year old son is just starting to quad.
This has me thinking about the safety of it all. I’ve read about plenty of bad injuries and deaths to really want to start off my son on the right foot.

For sure the first thing in safety is how to ride but there’s always the possibility of something unexpected happening.

I’ve always wore a good helmet while riding but not much more.
Now i’m looking at chest protectors, boots and pretty much full motocross gear.

I mostly ride big mountain trails, most are pretty easy but we come into sketchy stuff now and then and I ride with a bunch of nut bags on dirt bikes…lol( At my own pace though)

What does everyone else wear? I see guys in t-shirts and backwards hats riding… No thanks, To me there’s way to much to risk…

Hey guys Santiman here. Just picked up my first atv about a month ago. My friend rides a 2013 sports 850 xp and talked me into buying a 2016 Sportsman 570 for my first quad.

Here it is.

Very very addicted. My friend has 40 acres to play on. Few trail like areas and a good spring/mudspot. I’m trying to get out there atleast every other weekend. In between I watch alot of Ostacruiser videos (prefer them since he doesnt add music to the videos and you can hear the machines). Photo is on a creek bank he has running through his land.

Installed a few items since I bought it but I will create a build page for it since it will be in phases.

Peace.

Dropped of bike last week for 30 Shot instal, looking for 95 RWHP will keep you posted when complete:tools1:

Dropped of a 2016 Renegade 1000 last week for a 30 shot nitrous instal shooting for 95 RWHP will keep you posted on results:tools1:

just past 600 KM on my 2015 sportsman xp 1000
just got it new couple days before the 2017s dropped.
saved a couple grand though.

Everything is good up till the other day, when i snapped a rad fan blade just after coming out of the water. Heard grinding like gears, found the fan hitting the broken piece.

I dont want to do the relocate kit. the front rack is part of the selling feature.

Have considered wring a cut-off switch or a relay connected to a water sensor….

Any other options?

In the scrambler forum, some people suggested installing a sportsman fan because the fan blades are connected together…???? mine are not.
is this from older models??

The replacement part is not cheap either. over 200 US / 300 here in CAN

Hello everyone, I’m gcr from Vegas. Just thought I’d check in and say hello. I figure I’ll be needing some help from the community. I just bought a 2006 trx400ex from a guy down the road, it’s in really good shape, seems to run pretty good. Haven’t got to take it out yet but so far so good for the little I’ve ridden it. I chose the 400ex because of the reliability of that motor and I needed a quad that would fit in my Tacoma bed, 4dr short bed, it fits perfectly, just need to get a bed extender. It fits between the wheel wells. Should have plenty of power for my needs, I just like ride and tinker, nothing outrageous. It seems to have too much oil in it though, need to hunt down a service manual and learn all that stuff.

I have a 2000 Scrambler 500 4×4 with everything stock. The belt was slipping so much it was hardly rideable. I put a new belt with no luck and now I have replaced the primary clutch and it still has a good amount of slipping.
Is it possible I just ruined the new belt and that’s why it’s slipping now?

I did get the new belt pretty hot prior to putting the new clutch on. I was pretty far from the house when it began slipping very badly.
It does alway seem to slip around the same area of the clutch, which is about 3/4 the way up the plate.
There is 2 1/4" Deflection which seems a lot, but it tightens up nicely as I give it throttle.

When it’s in neutral, it doesn’t slip at all. Only slips under load (my body weight). I don’t weight that much. 190lbs.

The cluth alignment seems to be fine. Spacing is even on both sides of the belt.

Any ideas would be very much appriciated.
