  1. i left my bike (2003 ktm 125 sx) sitting for a few months and i guess it got messed up with old/bad gas mix because it wouldn't start. after the bike sat for a few months i finally made time to remove the old gas mix, change the spark plug, and remove/clean out the carb/jets. i checked the manual to make sure what positions the fuel tank valve were for on (vertical) and off (horizontal) were (since it had been so long). i removed the bike from the stand, mixed up a new gallon of 40:1 gas, dumped it in the tank, flipped the valve to the vertical position, turned on the choke, hopped on and after maybe 2 minutes of kicking she turned right on and started smoking beautifully. i hopped off and kept my hand on the throttle a little and guided her outside where i dropped the kickstand and gave her some more gas at a little higher rpms. so far so good. then i thought i would give her a few minutes to warm up (idling) on her own...and after about 30 seconds she abruptly said screw you sir and turned off. i thought, ok, no biggy, been here before. so i rolled her back into the shade of the garage, upped the kickstand, and started the kick start process over again. after about 15 minutes i was drenched in sweat and a little confused, so i decided to go back inside for a while. i turned the choke off and the fuel valve back in the horizontal (supposedly off) position. gas started pouring out onto my garage floor, so i reversed the fuel valve and after 3 or 4 seconds it stopped. next i slowly turned the fuel valve again for a short time just to see where the fuel was coming from. it kept pouring (i believe) from the overflow tube connected to the bowl at the bottom of the carb that holds the floaters. i can check that again if need be, but im almost certain thats where it was coming from. what's going on here? why wouldn't she idle for me sans throttle? why wouldn't she start up again? why did turning the fuel valve to what is supposed to be the "off" position result in gas spilling all over my garage floor (finally, i just left it "on")? sorry for making you read a novel here, but i tried to provide as much detail as i could since i am no mechanic and have no clue if any of my actions or the order i took them in could be the cause of this crap. does this stuff sound familiar to anyone? advice? similar experiences?
  2. ok, so ive been very slow to tackle this, but over the last few nights i went and removed plastics, gas tank, subframe, airbox, etc...and got the carburetor off. i took all of the outside screws and springs off with no problem. when i went to remove the bottom pan that holds the excess gas and floaters, it has 4 soft brass screws that i just knew were going to be a bitch to get off, so i pre empted trying to get them off with a few sprays of wd40. 3 of them came off, somewhat easily...but the last one, i cannot get it. i have stripped it i guess. i tried hammering a sharp phillips head bit into the head to carve out a new pattern, but no results. take a look and let me know if you have any advice on how to get this sucker out or what to do next! thanks!
  3. so...dont drain the fuel mixture back into my gas can but get rid of it instead? i wasnt aware of this issue. how long does it last? what is meant by "stabil or startron" the gas? is this something specific to 2 strokes because of the oil or can straight gas in a 4 stroke go bad as well and how long might that take if possible?
  4. thanks for the responses. drain the tank and the spark plug were the only two ideas i had of where to begin, but i figured i would ask first. i didnt even think about the air filter. how easy is replacing the jets?? thanks again!! any more ideas welcome! ill post my results.
  5. sorry for the length...the most important information is at the top and bottom. i bought an ’03 ktm 125 sx in october 2014. worked great the first few times i took it out, then i had some trouble with the clutch and took it apart testing every piece along the way, finally figuring out that i needed to replace the master cylinder. got another half ride out of it and severe tranny oil leakage indicated the need for replacement of the transmission case gasket. i added a tach/speedometer and, as it is an older bike at this point, had to make a few other minor repairs and adjustments, but nothing too painful. unfortunately in feb ’15 my riding buddy was murdered and i gave up on riding for a few months. my final ride was april of ’15, a memorial ride for him in our favorite place. i went off trail, cut across a piece of desert i had cut through many times before to make a shortcut back to my truck and thought i was riding across flat land, but the grass was camouflaging a small trench which caused me to endo and the bike eventually landed on top of me, breaking an ankle, wrist, and some ribs in the process. i wasnt going to be able to take care of myself for a few months, so i was forced to pack up and move from California back east to South Carolina where my parents lived. a friend checked the bike before we went to the hospital that day to make sure it still worked, and it did, speedo/tach and everything just fine. when loading up the bike to move i noticed the speedo worked as well. it then sat in storage for 3 to 4 months until i was able to go over and run the engine and ride it around the parking lot a little…worked fine, but not the speedo. it has now been another 6 months and i have tried unsuccessfully two times now to run the engine and ride around a little bit, but i cannot get the damn thing to crank! its been so long now since ive ridden or worked on my bike that i feel like a virgin again, and i have absolutely no idea what is going on and why it wont crank (choke is on, fuel line on, gas tank shaken a little to mix gas and oil) and why the speedo wont register when the bike moves. there is a small reservoir under the gas tank on the right hand side where the fluid inside is well under “min” line but i am not sure what goes in here and where it is loaded from (clutch oil, transmission oil, brake fluid?). other than that, what should i look for? are there any obvious things i should check or try to get it to crank? it hasnt even been a year since i was repairing and riding my own bike on a regular basis, but now my riding friends are gone and i havent ridden in months and all of the sudden i feel like a complete idiot. help, please! even the most basic advice is appreciated!!
  6. thanks for the advice everyone...im so glad the responsibility for this bike does not fall on me. my friend, however, is in a terrible spot. the bike was supposed to be in great shape. the owner told me/us it was "basically a brand new engine." to be honest, he is not all there in the head and has his own set of problems going on, but he does know right from wrong, and i can't see him deliberately misleading any of us like that. he doesn't even use the yamaha any more, because he came into a honda 250 4 banger somehow, so its not like he was just waiting for somebody to repair it. i honestly think when my buddy tells him the cost of the repair, he just may say "thats way too much for a bike i don't ever ride so don't worry about it." it will definitely be interesting to find out how it goes telling him. i will definitely download the manual and look up those tools so i can try to talk him into tackling this project with me instead of giving it to our mechanic. btw, our mechanic is also our friend. he sells us everything at cost and goes out of his way to make sure we are satisfied. i trust him implicitly, however that does not mean he is always able to give the best deal and i realize that businesses are for making money, not friends. thanks again for the advice, and anything else that anyone can add would be helpful and appreciated! send all donations to....lol.
  7. my ktm was out of commission for the day, so our riding day was almost spoiled, until a friend offered to let us use his spare bike that he no longer rides due to the fact that he has a better one now. that friend happened to be the cousin of my other two riding buddies, but he suffers from ptsd and I'm not sure he is legally responsible for making his own decisions, therefore one of the cousins decided that he was going to take on full financial responsibility for the bike, due to the following facts: we are all experienced riders and he said the bike was "basically brand new" and claimed that the engine was "just rebuilt." i ended up using my roommates bike, because i thought it would be more comfortable for everyone if someone from their family rode the spare bike. the bike ran ok for about half the day, and then my roommate was going into a berm, shifted down from 4th to 3rd, made it about 20 or 30 feet with complete power, then the bike proceeded to just bog out and and we were never able to get it started again, kickstart or bump start. we pushed it down a hill several times after trying to kickstart it failed, and it sounded like it wanted to start, but it wouldn't. i had a spare spark plug in my bag, so i offered it up to try (even though the numbers didn't completely match). after looking at the old spark plug, it was obvious that it was no good and that was at least part of our problem. we then went back to give kickstart a few last kicks to see if we could get any luck, but unless you consider a seized piston luck, we had none. we towed it back to my truck and the trailer we rented, and checked out a few other things, such as the dirtier than hell air filter. it just wasn't going to start. we loaded it back on the trailer and took it to a trusted friend who owns a shop, and told him to take his time. after two weeks, he called back and said that both the top and bottom end of the bike need to be rebuilt and it is going to cost anywhere between $1200 and $1500 to fix. with prices like that, we are scrambling for ideas. personally, I've only ridden and dealt with ktm in my (short) riding days, but I've been researching yammies and it seems that engines from 2002-2003-2004 range will fit this bike. my questions: 1. does the price to rebuild the top and bottom end sound reasonable? 2. how hard is it to do some of the labor intensive parts so i can save money by doing some of the work for the mechanics? 3. how hard is it to crack the case in particular? i know it takes a long time, but is it something i may be capable of doing? our mechanic said that most of the labor costs are coming from the six hours its gonna take to crack the case? does that sound accurate? 4. should i just try to buy a used engine from 02-04 and try to fit that in there or pay a mechanic to? 5. question 5 is just open ended advice that anybody might be able to offer my friend. sorry i know this is long, but its a very complicated situation. i don't bear any responsibility here, but i feel bad that my friend is having to bear the brunt. spencercan

    bike sat for a very long time, however recent tune up has confirmed bike in excellent condition top to bottom, just needs new fork seals. everything stock except for fmf pipe. touchy clutch, looking to upgrade power (like the others lol) to 250 or (preferably) 450 or street legal enduro.

    low hours, very reliable, no major wrecks or common wear and tear. bike sat unregistered for several years, so really only 3 or 4 years of riding on it. upgraded fmf pipe and renthal bars, along with fat rear tire for extra torque when needed. looking to upgrade power to 450 in future.
