Hey all new to the forum.... We ended up picking up a 2006 Suzuki z50 quad sport and took it camping this weekend. The guy said had a new top end and just put on a new belt. Seem to work fine for a little bit and then it lost power at the rear wheels. Belt was not in bad shape took a look but it just did not seem to have enough power to get my little guy moving. I pick up the rear end tires would go. Set it down lacked all power. Any help would be greatly appreciated it did run like a top also. To add to the bad news on the way home I ended up losing the seat so if anybody has one even if it's in rough shape would love to get it or if you have any ideas open to suggestions......
I had a quad fall in my lap a couple weeks ago. The only things I knew about it was it was a Kawasaki Bayou 220, was in pretty rough shape and was free. I couldn't say no to a fun little project. I've been looking a different ATV forums gathering quite a bit of info and decided this was the one I wanted to join.
Thanks to this forum, I found the VIN under about an inch of mud and cross referenced it to be a '98. It had been sitting outside for at least 5 years and was told it ran when parked, but had no brakes. Squirrels or mice had been chewing on the handlebar controls and it's generally just kind of beat up.
So far, I've gone through the carb (not near as bad as I expected), freed up the brakes (will probably need new cables), replaced the spark plug, air filter, petcock and put a new battery in it.
The gas tank had been empty and looked clean so I put some fresh gas in it and tried to crank it today. I got a neutral light, but the starter button did nothing. I tried pull-starting it and it wouldn't fire. I checked the plug and wasn't getting a spark. I started digging and found some potential issues and some definite problems.
I have a wiring diagram I found on here but it's just a picture or scan out of a book and hard to read. I don't see a reference to a black/yellow wire, which is my first problem.
First, it that a factory crimp? One of those wired looks like it goes to the connector in the 2nd pic. Is that just a spade lug type connector? I pulled on it with some needle nose pliers but it didn't seem to want to come off. In the 3rd pic, should there be a fourth wire?
I've read through and bookmarked the threads Andrew Baker and Arizona have going but I figured I needed to start with these obvious issues first. I have lots of pictures, so if there is something else you want to see, just ask. If I don't already have a pic, I'll take one.
I have two 2003 Suzuki Ozark 250s, both 2-wheel drive. Last time we rode them about a year ago, the red one was not running well, didn't want to idle, backfired a lot. The green one ran fine.
Fast forward...I ordered a carb kit for both of them, thinking the red one has some trash in a jet. Both of these ATVs have had little use and I've always ran the gas out after use (put an inline cutoff valve in gas line). I pull started the red one to verify it was still running bad. It will start and idle, but as soon as you give it any throttle, it dies instantly. Give it a little choke, dies instantly. Took the carb apart and it was spotless. Went ahead and cleaned all the holes with carb cleaner and blew everything out with compressed air. All new jets, main jet holder, and needles. Put it back on and nothing changed. Starts, idles (not for a long time), but dies as soon as you give it gas. Same happens when you put the choke on. It does the same thing when I try to run it turned to prime on the petcock as it does in the on position.
Not an air filter issue. It is clean and it does the same exact thing with no filter on it.
Thought maybe there was a float issue or maybe a damaged diaphragm, so I took the carb off the green Ozark and put it on red. Started up and initially ran normal and revved for about 10 seconds and then started doing the same exact thing. Starts, idles (not for a long time), but dies as soon as you give it gas. Same happens when you put the choke on.
So...not the carb
Thought maybe vacuum petcock was bad, but there's no gas in the vacuum line going from petcock to carb and gas flows freely when on prime. I even plugged the vacuum line at both the petcock and carb end and tried to run it with valve set to prime. Gas flows freely, but does exactly the same thing. I unscrewed the screw at the bottom of the bowl and gas flows thru carb and out bowl drain line when petcock is set to prime.
So, I'm assuming petcock is good?
Checked spark plug and it wasn't fouled. Reset gap, didn't help. Will swap plugs between Ozarks tomorrow but I don't think that is it.
Anyway, that he history and now you're all caught up. Scratching my head. Valves? These were bought at same time and have had little use. Suggestions?

Hey everyone, hoping to get some help here... my kids 03 KTF 50 Quad has always ran great... they were riding it a couple of hours a few days ago and it died a couple of times (not normal) but started right back up. A few days later my 5 year old wanted to take it for a spin so I started it (2 pulls) and he took off.. he made it a couple hundred yards and it died and we havnt been able to start it since. I have new gas, good spark and 120 psi compression.. it will not start with starter fluid in the intake or even in the cylinder.. the fuel bowl has fuel at the carb... what am I missing? It’s driving me crazy!!
So i was riding the other day and my quad randomly shut off. It started back up and ran completely fine for a little while and then it started idling terribly.
I cleaned the carb and changed all the jets and everything except the float due to the rebuild kit not coming with one and it actually runs worse then it did before.
It will run and idle decent now but when I give it gas it dies.
Does anybody know what could be wrong?
I also changed the spark plug and air filter along with the oil and oil filter.
i have a 2000 suzuki king quad lt-f300f that i picked up as a project bike. it didnt run well when it was parked outside 5 years ago. it cranked after putting fresh gas - but would not run below half throttle, i took apart the carb, cleaned debris, and re-assembled. i suspect that the pilot needle is sheared off - it never protrudes into the throttle body through the pinhole. now to get the bike to ALMOST idle, the throttle idle adjustment knob is all the way up/in. the pilot needle is turned almost all the way in/up (if i understand correct, it should nominally be out 2 1/4 turns or so). and like i said, it will ALMOST idle. floods easily, rides rough.
wanted to hear from those more experienced than me with suzukis - and im self-taught atv repair, so dont laugh too hard if my verbiage/part names is way off.
facing the driver's side of the bike [US] there are three hoses on this side of the carb. without a service manual or way of knowing what was messed up before i got it, i think i have them right: front hose as a vacuum to the petcock, middle hose as vacuum to the fuel pump, rear hose as fuel line from the fuel pump. running the bike in prime position results in flooding even while riding. with all hoses disconnected from the carb, fuel slowly drips from the vacuum line connected to the petcock.
so just my speculation is that the diaphragm in the petcock is split, and the pilot needle is broke off - causing my inability to not quite idle and the rough ride. this suzuki is hoses and cables everywhere compared to the honda ranchers and yamaha warriors i am used to. I would like to have a plan rather than: replace everything at once.
is my speculation on the right track, or could something else be at play? say, if the compression was non-existent, would that cause non-idling? i am all ears, look forward to the input.
