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

Ok, so I bought a 2006 bayou 250 for 200 bucks, kid couldn't start it and had no idea why it wouldn't run, I pulled the rope and felt what I thought was valve to piston contact, he wanted 500 and I talked him down to 200 and brought it home. Sure enough, timing was way far out, timing chain incredibly loose. So for fun I re-tensioned the timing chain and re timed it, got about 120lbs of compression, pretty low. I cannot get the chain very tight but the the tensioner seems to work fine, the chain guides don't look very worn. Also, when I took the head off the valves don't look bent and the piston has no discernible marks on it. Is this an interference engine? I sure thought I felt some contact with the pull rope but maybe no permanent damage was done? Anyway, I plan on doing a full top end job as well as timing chain tensioners and hopefully that'll cure it. Is there any reason other than chain stretch (I measured it and it's ok) or guide wear that would cause the chain to be so loose? Thanks!
Hi guys I'm in the market for a new ATV. I narrowed my choices down to King quad 750 Grizzly 700 and Rubicon 520, I own a 2006 500 Rubicon right now and I like the reliability and power for plowing. However it is not a capable ATV. When quading with other guys it falls short with ride quality and ground clearance. I also have a 500 King Quad 2015 which I like and will keep it for my wife. It is very strong and reliable also. However my plan is to sell my Honda Rubicon and replace it with a 2020 of one of the these mentioned above. Can anyone give me their take on one or all of these machines and why you picked what you picked?
Well its finally happened, its time to replace the belt on my 2011 Polaris Sportsman 500 H.O. Is there anything specific i need to know before getting into it? Is there one brand of belt i should get over another? I'm still on my first Polaris and plan to keep it at least another 8 years.
So my Yamaha grizzly 700 wasn't going into reverse for some reason but Jon and George figured it out on what to do to fix that problem for me. Jon Talks about how he was able to fix that problem my Yamaha Grizzly was having with the reverse.
On a side note we are so close to 1k subs! hell ya!

New to ATVing and by the end of the summer I'll probably be heading out into some remote mountain regions for some back country trail riding, and I'm wondering just what kind of stuff/tools etc I should bring along in case of breakdowns/events etc. Short list so far includes a GPS (probably a Garmin Montana 650T), a tire repair kit, and courtesy of my Mom one of those satellite personal locator beacons, probably the ResQLink+ from ACR.
Any other suggestions for stuff that might come in handy?
Aside from changing the oil and filters etc. what do you guys routinely do to maintain/tune-up your quad while the "season" KS over and the machine will be basically over for a few mos. I have a 2006 Sportsman 500 EFI APand I want to keep it a long time and want to do all I can to see that that happens.
Thanks in advance for your time,
I just traded my 400ex for an 04 predator tld. i was wondering how often i should change the oil and have the valves adjusted. it also has the front tire bent i was wondering what i could do to fix it? and what are some good cheap mods? i dont really want to change the sprockets.
thanks for your help in advance!
I came across the stuff, it is used for keeping plastic trim on cars looking good. Despite the name it works on all color plastics. If your plastics start getting the white clouding from lots of scratches or the are just looking old and tired...this is the stuff for you. It's about $10 a bottle and you apply it with a simple clothe. Rub it in like lotion, Absolutely amazing stuff.
Here are some before and after pics. This is all scratches from my boots on the plastics above and behind the motor.
