I figured you had probably cleaned them while apart ,just thought i would mention it. I usually start with the mixture screw 1 1/2 turns out from seated and adjust it until its running the best usually end up between 2 and 3 turns out. There is a tool that makes this easier Amazon sells several versions this is the one they recommend: https://www.amazon.com/Carburetor-Adjustment-Screwdriver-Motorcycle-Snowmobile/dp/B0BMTG92J7/ref=sr_1_2?crid=3UOBFMYX0H15D&dib=eyJ2IjoiMSJ9.TkpaU_CuOz3g4qBIsE0V3kMWh2LbJ8B--hRZEtRfDG6FSmQaIMAT_bCclJwC3rMnlvUzYzqd3kfdzlVuSTgdmgMuzklKuPmVjr-telZpWZ7oufONGBcix2tI-Rwb2C_ziP_sMT2DT7g3C8s0XdkPuIEQC912TUXCxnpQSyz9Bia0ezgQQFdmCzIAmYA24MGkC7qF6doGOWJFnrzv44euu_ifx_hXcVP3zMKQndygysd3y0i9_T3lYxf6MyfyiRp5xSS5B4n_kc2vi5fQWTjEfBK5ahg-fwd4528zGtdYGuw.dK0eY_t2Q-uOOZ41B5km52z_Z3V1Rmb8ydWD4HfRYh0&dib_tag=se&keywords=atv+adjusting+screwdriver&qid=1712854997&sprefix=atv+adjusting+screwdriver%2Caps%2C122&sr=8-2

Admin thank you for showing the log, the only DL that were successful were on the 03/07 date. none of the previous 8 attempts were successful Funny how all the past attempts have two logs at the same time, I understand only 2 a day but I was not able to DL once until the 03/07 Seams to work now, must have been a bug on either side. Thanks

Nothing beats a cigarette, Wish I still smoked The 02 sensor was bad (threads were stripped and it fit loosely in the housing but wasn't the real problem. Can disconnect both 02 sensors and no change. Throttle cable not really adjustable and IAC is integral to the throttle body and not serviceable.

It's likely that the O2 sensor wasn't defective. It quite likely was just struggling to control the mixture within acceptable limits and so reported it as not working. That's quite common with O2 sensors. They are one of the most miss-diagnosed components. I'd be checking the throttle cable adjustment, the fuel flow and pressure, the IAC operation(might operate on 5volts so be careful), and the spark plug gap and condition.

You have power to the relay, so now you need to check the relay is getting power to activated it, and that it has an earth on it's activation windings. If that side of the relay is operating, you need to check whether the power is getting from the relay to the pump, and that the pump has an earth. If you tell us what year and model this is I'll try to check in a manual how the pump and relay are actually wired. It's possible that the pump, or the relay, are powered and then get switched by connecting an earth to one or both of them.

Howdy y'all, I'm trying to fix a neighbors 2015 Brute Force 300. Came in with hard to start and won't idle except on choke issue. I pulled the carb and found the pilot jet as well as the emulsion tube partially clogged. Cleaned up everything, put it back together, still having issues... It will start right up on choke and will also start off choke if you give it just a touch of throttle but it absolutely will not idle unless it's choked just a touch. Also, excuse my ignorance but I'm assuming the "dial" thingy attached to the carb that turns in and out is for setting idle??

Not sure about the dial thingy but it should have a knurled thumbscrew on the side somewhere to adjust the ilde speed, and the idle mixture screw is at the front underneath and hidden up a tube. Did you check the rubber inlet manifold wasn't split, or that it doesn't have an air leak somewhere ? Tight valves can make them hard to start and not idle well too.

That sounds like a good choice, hope it gets you going.

This is a great benefit, and a great site, Admin thanks for all your support and hard work keeping the site going.

I'm familiar with the clutches on these quads, the difference is they utilize an engine braking system which is not on snowmobile CVT clutches. If everything in there checked out, then you may still have a problem relating to the electronic module. Could be its still not working properly.... Since they are likely not available new anymore, you'd have to find a "known good" used one which would be kind of rare. Good luck on your quest! (BTW, that's an inside joke - the quad you have was originally named the Quest I believe, at least here in Canada it was, haha)

This is much clearer and understandable than the diagram I found. Again, Thank You. Cavry

The diagrams I looked at described both the starter relay and the starter solenoid as "relay". I think we should describe the one with the starter cables attached as the starter solenoid.. to avoid confusion. In the diagrams I looked at the colours were different but the solenoid had two small wires operating it, one of which was black, and that one went to the starter relay and bought the 12v to the start solenoid to close it's contacts. The other one was supplying an earth to the solenoids windings. Then there was a white wire which in my diagram was shown as being connected to the battery's positive post, but which could be attached to the solenoid's battery cable post/terminal and it would serve the same purpose of supplying 12v power to the main fuse and then the bike.

Sorry I suck at these forums so if you see this submitted under update status, my bad. Anyhow this is a new shock for a 96 Yamaha Kodiak 400 4x4 it fits my 96 Yamaha Timberwolf 250 4x4 perfectly. Little narrower are the bottom than the original but everything else is perfect. I extended it to almost a half in from full extension because I’m pushing 350 pounds. It rides and hold me well. So if any of y'allRace driven shock. have been looking for one and didn’t want to do the research here it is.

Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.

The fan gets switched on when the oil temperature gets high. The fuel pump gets turned on when you first turn the key but then switches off unless it's getting a pulse from the cdi. The pulse from the cdi is the same pulse that fires the ignition coil, so if you have spark, you have the required pulse to operate the fuel pump relay, you just need to ensure it's getting to the pump control relay. When wires have no continuity, or have high resistance, it's almost right at the end of the wire where it crimps into the metal terminal, it either corrodes or breaks the wires inside the insulation. Wires do sometimes break if they have been chafing for a long time on something and worn right through the electrical tape, insulation, and then the copper wire, but that's easy to spot by the frayed insulation.

Not much to the throttle body that you can access. There are only 2 little holes where are the good stuff is located that cannot be serviced. Just pulled out the entire throttle body and cleaned it (wasn't really dirty) but don't expect it to do much.

That is the problem with this machine. Everything is in the throttle body ($1,200+). Haven't found a vacuum leak.

Well..... I don't know what I did, or didn't do the first time but after taking it back apart and going through it again, it starts right up without even choking it and purrs like a kitten. Thanks y'all. I have another question as far as coolant, I'll ask but please let me know if I need to start another thread. The coolant reservoir is reading on the Low mark, do I add coolant to the reservoir or in the radiator cap directly? Again, excuse my ignorance but this is my first time on a water cooled Quad...

Hi and thank you for accepting me . I am a crofter in the Scottish Highlands with a Honda TRX350D and a Yukon 150. I need help with the fuel pump on the Honda so will be pestering you all soon, cheers, semicolon😀

Hi again everyone! It has been a while since we have been on and complete change of direction for us. Instead of going out and finding nudist campgrounds we opened one and have already filled 40 seasonal sites for this year. we will see how the season goes.

I always like reading these motocross articles, thanks for sharing.

The black plastic knob attached to a cable is for adjusting the idle speed, not sure about a dial either unless that is whaat you are calling it. It sounds like there is still gunk or trash in your idle circuit jet or maybe the emulsion tube ,did you take that out and clean it. There is also a hidden jet down in a hole thats easy to miss.

I think this one also covers the Kodiak: yfm400fwa{M}-2000 copy.pdf

Start the bike and operate the choke.. You should be able to hear if it's working, or doing nothing. The choke only sucks fuel up when the throttle's closed. Soon as you open the throttle the vacuum drops in the choke circuit and it doesn't lift the fuel right to the top of the venturi where the discharge for the choke is. So it could be on and only go rich when you throttle off hard. It does seem unusual to have fluffy dry soot that fast. That's definitely rich though.. Oil looks wet black. You have got fresh fuel haven't you ? And a good grade ? The compression is probably meant to be nearer 175 Lb but that's warm and with a full open throttle and cranking at the right speed. If it comes up to it's 125 in the first couple of compression strokes it's a good sign. If it has to be cranked a lot and slowly creeps up with each compression stroke it's a bad sign. You could put a teaspoon of oil down the plug hole, give it a quick spin with the starter or pull start to distribute the oil, then do a compression check. If the oil raises the compression a lot it points to rings, not valves. Having a tight or leaking valve doesn't normally cause dry fluffy sooty spark plug. Leaking rings doesn't normally cause that sort of soot either.. Only fuel does that. Some bikes say what size the jets are in the parts manuals. You can look that up online, or in a service manual.

Dry black soot sure sounds like too much fuel. The mixture adjustment doing nothing is always a sign of something wrong in a carb. Since it's running good, no mention of missing or hard start etc I'd doubt the ignition is at fault. Check it's got a reasonably fat blue spark. Ignition systems with resistor caps or leads can have a skinny spark, but it should be blue. If it looks yellow it's a bad sign. If the soot is only on the porcelain tip it might pay to try a hotter plug. If it lost it's spark suddenly it might have a wet plug, but it wouldn't have black soot. I'd make sure the fuel tap was good and not filling the sump with fuel. And if it's got a vacuum controlled tap check that isn't letting fuel into the vacuum line. Then I'd start looking at the mixture. Choke's going right off, check that first because the choke only works when the throttle's shut so they run ok with a stuck on choke, till you throttle off, then air-filter, intake piping isn't crushed or blocked(mouse nest), carb breather tubes, fuel tank breather. It might be that the richness is intermittent, or caused by heat or the time run. So check the carb breathers, and tank's not presurising. Then It'd be off with the carb for another look. Check the float height(can be done before pulling the carb off) and that it isn't sinking, check the idle mixture screw tip and the seat the screw goes into for damage, check the float needle seat is sealed to the body, the breather drillings are clear, all the drillings are clear, the jets are the right size, the slide needle is the right one and attached to the slide, the slide isn't sticking. Reassemble and check the idle mixture is responsive. If it isn't then there's still something wrong in the carb.

Started off with a free moped I was gifted. I got it running and decided I wanted more fun so I cut it in half and welded it to the front half of a go-kart body. Turning it into a reverse trike. The thing was pretty cool but it was super slow so I posted it on a marketplace. Ended up trading it for a non-running chinese atv and some predator engines. Fixed up the old 125cc Chinese ATV and the predators. Sold the predators and rode the small ATV for a while until I sold that too, from there on I snowballed through anything with an engine, buying, fixing and selling for profit. My last project was a free 2000 suzuki ltf500 4wd quad that I just sold. Now I'm working on a 1991 lt230e that I picked up for $200.

I have been an avid motorcyclist since I was big enough to get on one. Street bikes were my forte. My doctor told me that due to an illness I had last winter that my bike riding days are done. This pretty much crushed me. A friend that was doing some work around the house( He was being paid ) heard me telling my wife how bad I was feeling. My wife said how about a trike ,would that be alright. said yeah anything I don't have to balance. My friend at this point stated he had an aty that was sitting for years and he would trade me for one of my guitars( I have 14 both electric and acoustic ) He stated it need work but I love a challenge so at the age of 78 I have my first quad.. After a carb and battery it started right up. I live on a dirt road so Told the wife to hope on and away we went. After just a short ride I am hooked.

Kind of the same senario, the only problem i have is deciding which one to use. So i just decide which one i havent started in a while and use it. Unless i am in a hurry and then i use the one that has a good charged battery.

I first road My Sons Bayou 220 in Aug of 21. I tore all the tendends in my rotator cuff and ripped My bicep coming down from a jump. Had surgery to repair My shoulder in the spring off 22. I know own two quads and am looking for a third! Even pain and agony can't keep Me away!

I have actually, but I only buy ones with a high level of good reviews. I have found that on more than one occasion where I’ve had a part failure from something purchased on Amazon, I should have read the reviews!

I know this post is a couple months old, but have you had good luck with these carbs? I had bought a cheap one on Amazon awhile back for a mower, and it seemed ok for the short time I had it...🤷🏼‍♂️

Welcome, and good luck with your Bayou, let us know if we can help.

Yes thank you, I'm still learning to navigate my way around. Anyways thank you for your reply!!

Welcome, sounds like your in the right place, we love to help get projects back on the trails.

Hello, I just joined this forum I look forward to the knowledge of other people have. I got a vandalized 99 Suzuki LT F250 quadrunner, so anyone knowledge on this would be greatly appreciated! Thank you very much!

Welcome to you as well!

Being new in the quad family it is nice to know there are places like this I can learn and get help

Hi all, I am new to this site and joined because I am always looking for help and ideas for my restoration projects I do. Also just enjoy riding around in my free time

Hi. I am new to this site. I am at Mariato, Panama and recently purchased and am rehabbing a 2010 Polaris Ranger Crew 800. The frame was eat up with rust so I have a local welder fabricating what needs to be replaced.

Most of the above. They took the plastics off and looks like they disconnected every electronic cable in the front. They also took off the throttle cable and unit, took out the airbox and disconnected every vacuum tube in that area. Closest I can tell is they were going to remove the carb but never got to it (though I will probably need to since there is still fuel in the tank and probably in the carb that has been there for who knows how many years). Thankfully, the engine is still all together. I can turn it over using the hand pull after opening the vacuum release, so it turns and seems to have good vacuum (though I don't have a vacuum tester yet to see what it really is). The front brakes don't do anything but the back work well. I am needing to download the manual (once I reach 10 posts) to begin to really look at it. Hoping to get a battery attached to it soon so I can begin to see if there is any power to anything and begin figuring out the wiring to re-connect it.

Hello name is not important but the game is,grew up in a shop, grandfather had,been working and messing around with stuff for some 50 years now. Worked as a Diesel mechanic for a while,then went to bmw, Volvo, Toyota,ect cars and trucks. After retired, as wife said I have to,I now work on small engines ect especially quads and bikes of all shapes and sizes,just am posting this to let it out that if I can help I'm here probably have done it or have seen it done before.

Its always a challenge putting something back together that you didn't take apart, but with the repair manual and the helpful people on this site its very doable, im doing the same with a Yamaha.

Hi! New owner of a Suzuki King Quad 300 that needs a lot of work to get going. Former owner ripped it apart to try to fix something and never got it together again. Now, I'm going to see if I can get it going and have some fun with it. Steve

Welcome to all new members. There ar a lot of good peeps here and lots of info to be found. Enjoy your time at QC!

Welcome Adam. I joined recently and have found help with my 2004 Suzukin LT80. Lots of good resources.

Welcome Larry, great place to learn, really good people , always willing to help and share experiences.

Thanks for the warm welcome, Gwbarm. Happy to be here! My fleet at present is as follows: 2000 Kodiak 400 - runs, good condition 2005 Predator 90 - runs, great condition 1985 LT230GE - project 1987 Trail Boss 250 - project 1998 Sportsman 6x6 - project 1999 ranger 6x6 - project

It was $5000. I think it was a '73. Its a V8. 351. Count the plug wires. If I would have bought the Stang I probably wouldnt have a drivers license anymore. LOL. My Dream car is a 68 Fastback. Shelby would be nice, but pretty much unaffordable for me. Not to mention gas is over $4 a gal now.
