2000 Trailblazer 250 questions

Recommended Posts

Hi everyone im new to the site and just picked up a trailblazer for a second atv. The problem i am having is that it seems to idle rough sometimes, and the mid range throttle seems to bog out but then later clears itself. Does anyone have any suggestions? I have had the carb off and cleaned it out. When cold starting it also takes a bit for it idle on its own. Also the previous owner installed a k&n filter on it. Stock pipe and jetting as far as I know. I dont know if that filter will cause problems. Also where should I start setting the idle mixture screw? I believe it is set at about 2.5 turns out from seated when I checked and cleaned the carb. What should it be around? I just changed the throttle cable and is there a specific way to set the oil pump cable? I didnt see any alignment marks on the pump. Does it just start adjusting from the stop of the oil pump or is there alignment marks to line up? Sorry for the long post, I have a Honda and not too familiar with the Polaris machines yet. Thanks in advance.

      Its in pretty rough shape and its gonna be my first atv, I worked on bikes before but nothing to do with quads. Anyways the quad has some problems and im tryna figure out what to focus on first. So the U joints i think are shot. The bike starts first try every time ussually have to give it a lil gas with the throttle and revs right up, idles fine but its running REALLY rich 3 starts and my brand new plug was pitch black

      Bike is L model

      I have an older (1987) Yamaha Big Bear 350.  I have arthritis in my thumbs.  Is it possible to replace the accelerator with a motorcycle accelerator (ie. twisting the handgrip)?  This would be more comfortable for me due to the arthritis.

      Does anyone know ways to regulate the speed etc other then the throttle screw? I have turn it almost all the way and it won't move on hills but keeps getting faster on flat gravel roads. I have a Chinese quad that's bigger but is a 3 gear so I just put it in first and let my kids go nuts cuz it might rattle it self to S... but it only goes so fast

      I have a 2000 Honda trx90 I got from a buddy for free he said it needed a carb so I put his old carb back on it to try to get something out of it and it does not have any Spark. I already replaced the ignition coil I don't know much about four wheelers but I am a technician so I do know my way around a motor any electrical help would be wonderful or specs I don't have the best digital multimeter either.

      So when im ridding in high gear randomly sometimes it will go into a persay limp mode and only allows a max of 30kmph and it sounds like a rev limiter, what would cause this and how to eliminate this all togeter as in the new ones with the over ride switch. its the sound that it does in low range or reverse. i want this gone period when i get stuck in mud i cann spin tires fast enough. and while im in high gear i dont want this happening. if you need more details the easier way of getting a hold of me rather then the forum is my email [email protected] i dont have time to check back here oftern but i get my emails right away.. thanks guys

      I've already posted here once about this ATV. Lots of people suggested i check the cam and after a couple months i finally got around to attacking it. I got it all apart and got the cam/rockers out. I'm almost positive they need to be replaced, they're pretty scored up and don't look too hot. Just wanted some final opinions before i drop the money on it. I'll also take feedback on the new cam i've chosen.

      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.

      I traded my dirt bike for a 2000 arctic cat 500 semi automatic. when i went to go pick it up the guy said it didn't get spark, so i thought it was going to be something simple like a coil. well it wasn't. first thing i did was take all the plastics off to get easy asses to every thing. so i bought a brand new battery for it seeing if it got power, it didn't. the dash wouldn't light up neither would the lights, so then i tried to see if the starter worked it didn't so i jumped the solenoid and the starter started turning over the motor. so i bought a new starter solenoid, when i installed it the electric start still wouldn't work , so i bought a new kill switch and starter switch that goes on the handle bars, when i installed it, the electric start still wouldn't work. so then i went to see if i could get spark by pull starting it, i didn't get any spark, so i bought a new spark plug, and guess what, still no spark, so then i bought a new coil for it to see if that would fix it. so i installed the new coil and guess what no spark still and still no power to the dash. so to sum it up i'm not getting any power any where to the four wheeler. so i cleaned all the leads and plugs and still nothing. so then yesterday i took the wiring apart to see if their was any frayed wires, and no their wasn't. does any one have any ideas what this could be i'm up for anything. also if any one knows how to bypass all the wiring just to get it to start i open to that to, or if someone knows where  i can get a wiring diagram.
