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?
Friend of mine picked up an LT80 that needs some work. The manufacture date is 11/1986
The fuel and vacuum lines for the carb were all disconnected. I picked up a new card and was hoping someone on here has a photo or knows how the lines are hooked up
Thanks in advance
hey so never ran into this before but i recently got a 04 honda rubicon 500. bought it from my doctor not running and the front brakes were locked up. cleaned the carb and it fired right up and runs great. these model atvs have drum brakes front and rear. not a fan. lost all brakes on this one when i hit some water and it got inside the rear drum case. so i ordered new shoes for the rear end no biggie. front is more complicated. has hydraulic drum brakes not sure who thought that was a good idea but the pistons in the drums rusted and locked up from it sitting with moisture in the drums.
so i had a choice to make- 1. buy new brake pistons ($120 for a set of 4) or 2. order super atv's disc brake conversion kit for $250. i HATE drum brakes so i went with the conversion kit. it said it was easy to install with no specialty tools. so i order it and turns out i have to press the studs out of my hubs to get the disc on.
anyone ever done this and if so how?
picked up this pos bike for $80 not running. took it home, cleaned the carb and bypassed the fuse- ran great (other than the rev limiter- those things are so stupid) Then one day out of the blue it starts flooding on cold startup and wont idle cold, but idles to fast warm. (too fast being about half throttle speed heh). I tried a new carb ($10) and new sp. new carb wouldnt make it run except on choke and then it was gushing white smoke. I had better things to do with my time so I parked it in a shed and used it for a work bench for a while... this last weekend, I wanted to take it along with the sportman to a mens retreat to let the younger boys have some fun on it-- took about 30mins to pull all the crap I had accumulated on it and then rolled it down to my workshop, put the old carb back on after adjusting the needle clip up two notches (leaner) and threw it back on the bike. Will turn over, but no fire. I didnt have time to check sp that day but just wanted some incite on what could be wrong with this quad (if it even qualifies as being called that)
Safety Is A Concern For Kids ATVs
The family is into racing ATVs and now the children want to get in on the action. How do you start with someone who is too young to drive a car, but yet sees other children their own age charging through the woods racing an ATV? A tough decision for parents, but with a lot of planning and instruction your kids ATV can become a reality.
Safety should be your first concern before getting the kids ATVs for their own use. You should plan on doing your research to make sure that you get the best kids ATV available for their age group and size. The research should include surfing the web and also by reading Consumer Reports—both of these will provide you with a tremendous amount of information on kids ATVs.
It is recommended that the youngest kid ATV riders should have an ATV that has an engine with no more than 4.3 cubic inches. There are not too many choices at this size for kids ATVs, but you want to ensure that your child is not riding a machine that it too large for them to handle.
As a concerned parent, you should check into the ATV Safety Institute. This group offers safety courses all over the country. The experienced instructors will teach you and your kids about pre-ride inspections, warm up exercises, braking, turning, and shifting. They also teach you about clutch and throttle control and about the importance of body position and simple maintenance. In addition they cover riding techniques and how to tackle obstacles, hills and different kinds of trails. All of these issues are important safety issues for your kids ATV riding.
So, what are the features will your kid's ATV have? One company has an experienced team of ATV enthusiasts that work with you on your kids ATV to hand select the perfect one. Each ATV they have is designed with safety in mind and they offer a 4-point safety system which includes a throttle limiter, an emergency kill switch, a safety kill tether and a remote kill key. The kid ATVs are safe and they come with a 4 stroke engine, headlights, an electric start and disk brakes. This company that focuses on safety with kid ATVs is Motorxtremes. They want to make sure that every kids ATV is safe and that the rider follows all safety precautions.
You should make sure that your kids ATV comes with all of the necessary additional safety equipment to make their ride as safe as possible. Every kid ATV rider should have a helmet with a full-face cover, goggles to keep dirt out of their eyes, gloves with finger and knuckle guards, a shirt with long sleeves and safety pads for their chest, shoulders, elbows and knees.
Make sure you and your children know the rules of riding ATVs. While you can not ensure that your kids ATV rides will be completely accident free, you can help them by providing the best additional safety equipment available.
