Just purchased my 1st Quad at age 59! 570se Limited Addition

background - bought a 03 trailblazer 400 a couple weeks ago. from what I can tell, has a k&n and custom pipe. No idea what if anything else has been done to it.

heres my issues. first off the thing pulls hard in the mid and top range. no break up, no sputtering, rips around as long as its revved up.
1. idle sounds maybe a tad low. when sitting at idle and giving it full throttle it doesnt really bog, it sounds like its sucking in too much air or something. makes a deep hollow sound for about a second then revs up.
2. in reverse and in forward gear, it has to rev up before it moves. I dont have a tach but im guessing it doesnt move until about 2k rpm, maybe higher. I can "brake boost" it, hold the brake and rev til i feel the gear kick in, then go. When i do that, it almost feels like turbo lag, it moves until it hits the pipe, then hang on.
3. Yesterday i was able to find a long straight stretch of trail, and I went wide open. It pulls hard with no break up, but at what im guessing was 40mph, i felt another surge of power.

Im not sure what any of this means but the only real issue I have is having to rev to move. if you guys have any insight or suggestions that would be awesome.

2012 850 xp sportsman
Recently I changed my shift shaft in trans and put back on the bike yesterday and put a new primary but idk if I put secondary right or not but both primary and secondary clutches spin but no output to drive. Any advice please

I have a 2005 sportsman 400 and i just sold my 15 camo 570 and feeling like i may have made a bad choice. Now im back in the hunt for another quad. Would like to upgrade to at least a power steering model or a big bore. Any advice what to stay away from would be appreciated. Im looking at 14 or newer 850 or 1000s. Thanks ahead of time!

I rebuilt the hubs and strut with new bearings and seals, I don’t have them together yet, I am concerned I seated the axle seal in the back of the strut to far, is it supposed to seat all the way in or is it supposed to be spaced back a little l, the old gasket left green marks so it looked like it seated all the way down, but now thinking about it I might I pushed them down when removing them. There isn’t a whole lot of YouTube info on that specific topic, thx for any help

All,

I have a 05 ATP 500 with a very low sitting front end. Upon researching how to make the quad sit level (springs, lift). I have found out the 05 ATP has 6.7" struts and the sportsman has 8.2". I'm contemplating converting it to the Sportsman front suspension. I have looked at all the front suspension components and it looks to me like the only difference is Spring/struts/a-arms/axle shafts/tie rods. What's your thoughts? I'm I missing anything ? Does this make sense to do? or is there a better route?

I have a 96 Sportsman 500 that has a the bogging issue when you give it gas. I've gone through the carb and airbox and was looking at my ETC switch. When I close it manually it has no effect on how the quad runs so I measured the resistance across the two pins and got zero resistance, like the switch is always closed. Anyone else messed with the ETC switch that may be able to shed some light on this for me?
