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 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?
Fully custom built with powder coated blue cage and front and rear bumpers has new aluminum roof with a blue flag printed on it. It was stolen out of my storage unit while I was on vacation they cut the lock off took the machine without a key and a bent steering rack. And put a new lock on the door when they left

Not sure how many of you will remember this or give a crap about it but back in 2016 I picked up my first old atv to rebuild. Yamaha bear tracker 250. I picked it up in NJ while I was out looking for a quad for my little guy since he started this atv thing after seeing a few old pictures of me in my hay day riding.
The person I was getting the 50cc quad had this one laying around and asked if I was interested in it. It was beat up and hadn’t ran in a few years. No spark the guy said and he left it to sit. I wound up taking both bikes.
I wish I had pics but I deleted the original post on Quadcrazy and lost the old ones on my phone when I upgraded.
This was the atv that caused me to stumble upon Quadcrazy since I needed a little help with the spark issue. So needless to say I fixed it, did some cosmetic work and she was good to go. I took it upstate and used the shit out of it for just about everything under the sun. This atv made it through some deep snow, mud etc. I decided to leave it up there and use it as a back up since it’s been about 50 atv’s later and I have newer machines now. But unfortunately it sat for some time and it’s a little beat up so I brought it back home and going to clean it up. Amazing how one year sitting has done so much damage.
This was the first atv that I owned in over 30 years! It’s the atv that brought me here to Quadcrazy where now I endlessly check the site to see what’s going on, who’s talking about what and who can we help with there problem or can help me with mine as well as the on slot of what I do today as a hobby with atv’s. It’s been a great pass time for me and my son with the projects we have gotten and get into. He’s learned how to ride so well it scares me a little watching him. He’s learned how to fix, maintain and upgrade atv’s. He’s insanely good with carburetors as well.
It’s a good thing when a kid wants to play in the garage over his X Box!!
The funny thing about this bike is that when we finished it we thought it was the best thing! We were missing a rack on the front and didn’t care since it looked ok, had no clue where to get parts or how to fix plastics. I was so new to this again since I was staring all over again and now had to remember things and also teach my son!
So we will be tearing into the bear tracker to get her up and running again as well as maybe a few new cosmetic changes and hang on to her for a while since I love this bike. The last two pics are the bike the day we finished putting it all back together and when it was upstate for the first week.
Had no intention of this post going so long. 🤷🏻♂️

in this thread, I want to discuss how 4-cycle atv engines work- what the different types are... how they are set up and which you prefer. To start off, are the cams on ALL atv 4-strokes powered by a cam chain? I know that on say a lawn mower or logsplitter engine, the cam is turned by the tappet, pushrods, and valve rockers. Which is better and why? Chain-driven cams or pushrod-driven cams? Are the pushrods just an old version and everything is transforming to chains or the other way around...or not at all? Just looking for some explanation, history, and downsides/upsides...
