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

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.

Welcome everyone! Sorry for the community being down these last few days. We ran into server issues with some database corruption. It took a few days to restore everything.

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

Those early Can Am's weren't that popular and those engines didn't stay in production after the v-twins arrived. It's worth checking into the clutch operation, maybe there's something that's failed in there preventing the full shift and limiting the rpm's??

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.

OK, now that we are through all the BS and I simply purchased the service manual, let me tell you the problem with the machine while I dig into the manual... The engine starts fine but does not idle. You have to keep pumping the throttle to keep it alive. You can go fast down the road and she goes, but idle no. It did have a bad 02 sensor but fixing that had no effect. In fact, unplugging the 02 sensor does not make a difference. Have not unplugged both - will do that tomorrow. The problem with the 850i is that all your sensors are in the throttle body and are not serviceable (and it is not a cheapo piece). Will probably have to start ripping the engine apart?

I have yet to find a free manual. The TM109919 is for all years so the 2014 would be fine. So again, what are my choices (cant find a freebie): 1. Post a bunch of worthless posts just be be cheap and get the manual for free 2. Buy a manual on eBay for about $30.00 (a CD) 3. Buy a download from some other stranger for $25 4. Donate $29 to you folks. I think I will choose #4 as I need it now, Maybe you folks will have the parts manual too and make it double worth while.

Good for you. Perseverance always wins. Giving up never does. You normally just check and top up the reservoir bottle. If you suspect it's using water you take the radiator cap off when the engine's cold, you top the radiator right to the very top, then you put the cap back on. As the engine heats the level in the overflow bottle will go up, and when it cools the level will drop. It's a good idea to familiarise yourself where the two levels are and always check they are moving from cold to hot. If the radiator gets a small hole or blown gasket the level in the overflow bottle will probably change with use, but sometimes the radiator sucks air in instead of drawing water from the bottle, then the level stops changing from cold to hot. Glancing at the level before starting, then again after it's warmed up, is a good way to spot any problems at an early stage.

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.

Yup, the setting in the book is just to get it running, then it needs adjusting while it's running, and warmed up.. A tool is a huge help.

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.

👍 You are welcome, glad i could help.

Update. After taking the carb back off and closer inspection I noticed that the throttle plate was opening to much before the main needle jet even moved any. I have attached a picture. The linkage arm that connects the two had so much play in it that one was opening and the other wasn't doing anything. You can see that I have the idle adjustment screw all the way in and it still wouldn't idle and the choke plunger didn't have any affect when trying to start it. Anyway, By putting a carb kit on it does nothing for this linkage problem so I went ahead and bought a new cheap carb. Put it on, works great. The air/fuel screw now works and the choke and idle screw actually does something. This type of thing can be a gremlin to find. Thanks Mech and Gwbarm.

Ha.. And the price we like too ! Good score..

Great you found them

good morning from finland

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.

I have been on something with a motor since I could walk and hang on to my dad. Been on dirt bikes, quads, 3 wheelers, snow mobiles, motorcycles, pretty much everything. But, I have just always gravitated to quads, and what I am starting my kids on.

You are aware that America is not a democracy we are a constuitional republic.

It did come from the factory with the AMC 304 V8 i am the second owner and i have had it since the 80s. Great engine but not needed in a Jeep with a 3 speed. Works perfectly for what i use it for, when im going through the woods i put it in 4 wheel drive low in 3 rd gear and never have to shift and just ease through the woods. I had a 57 CJ5 with the 4 cylinder 3 speed when i was in High School never had more fun with any other vehicle i have ever owned, they really made them for work in those days, plenty of power with the 4 wheel drive and low gear and the Willys 4 cylinder. Dont do a whole lot of hunting anymore, but i do love going to the woods and exploring.

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.

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 just had a Suzuki lt 230 quad runner do pretty much the same thing. Riding and bouncing around stirred up junk in the gas tank. I flushed it and it was fine for a couple weeks. Started doing it again , so I flushed the tank again and got more junk out of it. This time I put a inline filter in it. No more issues.

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 started when I was around 8 with a Honda big red 3 wheeler.. After a few years later I got a XR100, then a KX80, and finally a CR125. Then I had nothing until recently when I got my kids a Bayou 220 to ride around.

I am glad to be here and join in on this community.

What's up everyone?!

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

Howdy y'all. New here and excited to get a dead Bayou 220 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 QuadCrazy!

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

Yeah, a couple of my friends have sportmans as well, they seem to be good quads. I helped one of them fix their speedometer after they ran it with a dead battery and blew up some components on the circuit board.

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.

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

Hello everyone. New here and trying to learn everything I can. Bought my first atv this weekend. 94 Polaris sportsman 400. It needs a little work but only has 540 miles! Excited to learn from you all. Adam

new here. just trying to learn some stuff

My wife said the same but about 2!!!!!

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

iam a huge ford fan and I liked that gt500 a lot.. I liked the broncos a lot especaily wen I saw on a tv show called trucks wen the guy rebuilt one and it was awesome... The 78 1/2 ton is up there to with my favorite trucks next to jeeps
