posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
-fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
-along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
-I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
-can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
-it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
-I THINK it has a mikuni model x carb - diaphragm is ID 26mm OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
-last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
-any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

Hi, do you know if that exists ?
Hello everyone, did a search and not successful. Purchased new 2017 Sportsman 570 sp and my power steering is not working. Seems to have a mind of it's own. Works then it doesn't. Dealer says there's not a fix. Thought it was just me and it being a brand new machine with 4 hours on it. Dealership said it's this model only ? Not sure what a person in this spot is suppose to do and wondering are your thoughts mite be. Thanks

Got my first quad this past fall a 2011 Grizz 700 EPS, and now that spring is getting close I'm thinking about getting back to work on maintenance stuff. So couple questions...
1. What are some regular maintenance points that are done in the spring on these machines?
2. What are the regular maintenance points that are done every so many miles that I should look to do?
Other than changing out a torn CV boot and cleaning some crap out of the air intake foam in the fall I really haven't done anything to the Grizz. So not knowing its maintenance history I'm assuming it's due for everything...all fluids changed out etc.
Oh btw it's only got about 750 mi on it right now.
Thanks I'm all ears

thanks for your help in advance!
Currently, QUADCRAZY is undergoing site maintenance and upgrades over the next few days. There are a few sections that are down: Video and Trails. They should be back up in a few days as everything else is done first.
Most of the work is due to security updates and getting ourselves up to date. We've made so many additions over the past few years, things internally are not working the way they should be.
I am glad to say that we were offline for an hour or so, and now back up. People can log in and all.
The chatbar is gone for now to set up for a newer style bar. The chatroom has been defaulted to our original basic chatroon. I'll bring back the other chat in a couple of days.
Our video section is getting a little overhaul also.
Trails will be down through next week.
User's garages are also down for now.
Please post in this thread if you experience issues outside of this stuff. Thanks!
