Hope someone can help with this one. We took our 1984 Honda TRX 200 to the shop and they had it for about 2 weeks before they finally called and said that they had cleaned the carb and changed the battery and that it had started up. We went and got it and when we got home it would not start so we called them, they said bring it back in, so we did. They called us the next day and said they changed the spark plug, and that it was running. We went and got it again and it ran when we drove it off the truck. We parked it for about an hour because we were going to get ready to go on a ride. Well, it wouldnt start again. So we called them and they said the last thing they could do was order a new CDI box and put that on. I decided to just buy it myself, so I didnt have to pay them labor again. We put the new one on today and its still not starting. Does anyone have any ideas on what we could check to see what in the world is going on with this thing? Please and Thank you

Well I have not had time to work the minor bugs out of my atc250sx and I went and bought a 1985 trx 250. I couldnt pass it up for $100 the previous owner said it was running and he heard a clink or snap sound and then everything froze up. cant get it out of gear so he figured it is a transmission problem. my first question is how do you go about removing the drive shaft? any ideas on what the problem may be. motor wont shif out of neutral. It happened right when he shifted into gear. it stalled the engine and never went back into neutral. if any one knows how to work on this dinosaur

anybody can tell me what is the outside diameter of a kingpin bushing # 51215-950-000 Thanks Gignac02

I have a new battery and my machine will not start, it just makes a clicking sound

I have a 07 trx 400ex. I had issues with the shifting. It would shift up to 2nd then hit a roof and go no higher. I took it apart and split the case. The shift drum works fine when shifting by hand or with pliers. But when you use the gearshift plate and shifter it will not move. Any ideas?

I am selling my Honda trx 70. It is all original everything, I have owned it since 1988 and it runs excellent and everything works as it should. Trans is good, brakes are good, steering, levers & cables, tires....everything perfect. The only issue with it is that it needs a seat cover since the original one is cracked in a couple places Plastic is scratched up a little but has zero cracks. The decals are all there but some are a little rough. ( It is 28 years old) It's stored indoors and has been for about 20 years. Perfect for small kids or bigger kids. I am 290 lbs and it carries me anywhere and everywhere. surprising power for a 70cc. Starts on the first or second pull (If I remember to turn on the gas) Asking $750 or make me an offer - can email pics if interested. (not sure how to put them on here. I am in central Arizona -Payson, Az. email me at [email protected]

ive had this little bike for a very long time and always worked great, start first pull every time, recently i was driving it and it started running rough when i was almost home, it died as soon as i pulled in the driveway ( no spark ) i fixed that problem ( i have tons of parts ) but it still wouldnt start, a couple days ago i went out and gave it one pull and it took right off, i had to hold the throttle open a bit but it was cold out and i didnt use the choke so i expected to have to do that, i let off the gas and it stalled, i left it sit for about 20 minutes and went back out to try again and it wouldnt start, so i took the carb off and cleaned it pretty good, still wouldnt start, went out yesterday and it started right up, i kept it going for about 10 mins by holding the throttle, its running a little rough but not too bad, i let it stall then tried it again and it started no problem ( about 5 or 6 times in a row) so i walked away thinking just need to tune the carb a bit, tried it last night and today and it wont start again, one thing i did notice is that i dont need to use the decomp valve every time i pull it ( sometimes every time, sometimes i can pull it 20 times before it needs it again) keep in mind the motor is in pretty good shape, it doesnt smoke and when the decomp is doing what its supposed to it will rip the cord out of your hand if you dont use it, anyone have any suggestions?? im about to lose it, im leaning toward a broken valve spring or a bent valve, oh yeah, when you pull the choke on with the breather unhooked, you can see gas shooting out of the back of the carb, any help would be great thanks

I need to replace the starter on my 1993 Honda TRX 300FW. How do I find out which manufacturer made the original? Thanks

Hi, can anyone help me with starting my quad 2000 model trx 350. unable to start as cant get neutral light to show. even when its in neutral it wont start. goes into gear well and runs well once it has started. It started playing up last week I could fiddle with gears and get it back again, but its not coming up at all now so I cant start it. Any ideas Jon

hey all, so i been running dirtcars for years now and im getting out of it so i decided ima get me a 4-wheeler to have some fun with. Im looking on some input on yall thoughts as to which quad to get, ive narrowed it down to either the yfz450 or a trx450.

Last year i have changed the timing chain on my 1997 TRX350. I did use silicone between head and cover. now it is leaking. I am looking for a better product than silicone to put between cover and head. What should i use?

I have a 1997 Honda fourtrax 300. It runs great but, I almost got stuck in the mud this weekend so, I am now thinking about mud tires and some minor mods. What do you guys suggest for some minor modifications to get some better performance? It performs pretty good but, sometimes when driving pretty hard, the clutch slips a little. I am also thinking about a lift kit. Which one would yall recommend?

Hello, new to Quad crazy. I'd like to say thank you for having me. I bought a 02 honda trx 400 ex for $200 with 4 extra very nice ITP rims and tires for the dunes and 2 stock rims with drag rear paddles. didn't run. got it running. They owner before me said it has a big bore kit in it. Does that mean it's been bored .040? or could it be any sizes bore kit? And if it is .040 over. is it a 440? I've seen a 416 a 426 on the forum. so I'm not really sure of the size difference between stock engines and bored engine when there bored out. I'm at this point right now. bought a rebuild kit for the carb. On theses engines what would cause the engine to knock? A buddy sold me the quad and it was his sons so he didn't know what was wrong with it. just that it didn't run. I'm hoping to get a little help from the forum. how would u go about trying to figure out what is wrong. Would the bored out kit cause the motor to knock. It smokes kinda white sh blue smoke. I was also told the the connecting rod is pressed to the crank. if this is true can the connecting rod be removed from the crank to replace just the connecting rod or do I have to replace both? i'd like to rebuild just the top end. I'm a small guy only weighing 125lbs don't really need a bunch more HP. But what ever HP parts are in it. I'm going to try and replace them with the same. what rebuild kits would u use?Never rebuilt one before this will be my first. There seems to be a whole bunch of racing upgrades on this quad. The axles are even longer for better handling. Thanks everyone I'm new to all this. Thanks for reading all my questions!!!I want to ride real bad. Cant weight!!! Thanks again for having me and all your help!!! Thanks Brad

Having trouble with engine not turning over fast enough to start even with brand new battery. Seems like there is too much compression for stock battery and stock stater. Is there a high performance version ?

Hi All, I am a new member here and am trying to find the VIN NUMBER for ATV in title. I have a manual and shows where the VIN is supposed to be but it is not there. Can anyone tell me where it could be located? I am wanting to purchase the bike and I want to make sure it is what the guy says it is. BTW, just getting a bill of sale with it . Please reply ASAP Thank you Jack

Hello Forum Members. I have a 2001 TRX 250 Recon that I purchased about 6 months ago and now experiencing problems with the main fuse blowing when I rev up the engine. Let me give a little history on the ATV. The previous owner says that the battery is approximately 1 to 1 1/2 years old. The ATV will start when jumped, but will not restart immediately after turning off ATV. If the battery is charged while out of the ATV, the battery will last about about a week until it's dead. The ATV ran great, the only problem I had was the engine would stall after a hard acceleration. A quick pull on the pull start and I was good to go (battery would not crank motor). I installed a new battery and that is when I started having the problem of the 15A Main fuse blowing. I would start the motor and rev it a couple times and then the fuse would blow. I replaced the battery with the old one and replaced the fuse, thinking the new battery was the problem, and the same thing happened. Did the installation of a new battery cause my problem? I read in other posts about the regulator/rectifier being the cause of the main fuse blowing, so I unplugged it and the problem wasn't resolved. Any ideas or places to start looking? Could it be a bad alternator being it sounds as though the battery wasn't charging? Thanks in advanced for all replies! Phil

THis one has me a little mystified. I rode it yesterday and all was great, I rode itthis morning and it won't accelerate. It starts sputtering and sounds like missing, I changed plug with no effect. Can someone give me a hand here?

The black trx 450 is stock except for the Pro Circuit T4 Full exhaust, both running Razr 2's. Good day of quading on August 30th 2012. This main trail were riding on is pretty sketchy because trucks, jeeps and 4x4 quads can be coming the opposite way at high speeds Ive had a few close calls already on these trails with oncoming riders.

I am working on an early 90's Honda 300TRX 4WD. The problem is no spark. I have downloaded a manual but it has not helped yet. The problem is I have no voltage to the ignition coil. Any idea why there is no voltage from either the BL/Y or the G wire that connects to the ignition coil? Thanks in advance!
