Why Wont It Start Ah!

[YTM200BOY]

i got a yamaha ytm200EK and i recently got a float valve.. Before we put it in it would start up fine but now it backfires and wont start i spotted a wire broke possibly going to the back electric thing. We started playing with the wires connecting it places and it still wont run!! is it possible it wont start in 45 degree weather??? some1 got a idea thanks _JOE_

First idea---Dont go randomly plugging things in if youre not sure where they belong----CDI components are very unforgiving.Go to the front of this site , get a wiring diagram. If not I can scan it for you. Backfires can have plenty of different reasons, Including lean fuel, so dont instantly blame wiring. Does it have spark when you crank on it?

remove the spark plug.. pop it inot the wire and ground the tip to the cylinder, pull the cord and check for spark.

if you have spark.. pour a few drops of gas into the cylinder . put the plug back in and give it another go.. if it sputters a few times and dies.. i'd guess it's carb related somehow....

go from there.

spark is there and about the wiring a local guy that just died rewired it and believe me it is nothing like the real diagram he just wired it to run then again it was only 50 bucks but man i am so mad it wont work! i recently put stable in my gas does this have to do with it??

[YTM200BOY]

yes i removed the spark plug the orignal plug was black on the bottom and i replaced it with a new champion and it does the same thing!!!! AHH this bike is nothing but problems for me i qoute my dad 1 step closer to running then 4 steps back" this is so true!- JOE i am thinking about putting it in the middle on the street and lighting it on fire!! well not that far lol. i want it and i want it to run instead of being a ornament! =JOE

Check the flywheel key a backfire can shere the key a little changing the timing, your better off using a known to be good USED plug not a new plug.

First mistake was the champion plug. Get a NGK. If your getting spark, and the plug is black maybe your just flodding it. turn it over 5 or 6 times without the choke or giving it gas then choke it.

Since the last thing done was the float in the carburetor, you'll have to assume its a fuel issue. I would take the carb off again and inspect that everything is put together correctly. If the float is stuck or the needle is bent etc it wont run. These things run on so little fuel, it needs to be right. CLean the old plug with a toothbrush not a wire brush or use the new one, as long as it works when you test the spark. Was the engine noisey before. is there a chance the timing jumped? If not, youre probably ok. Good luck.

lol the black plug was a ngk not a champion lol and ebecme i put the airbox on it and its a tight fit on this bike if * didnt know and the wires were in the way so i put the wires on the side and as i was taking it off "airbox" it may have ripped a wire off the rear electrical thing because there are 3 wires that lead to no where and like i said the guy that rewired this bike died so i cant ask him.......So i think im screwed! Also before this happened when i would pull it it would sometime be hard to start like i would pull it and it wouldnt come out all the way now it seems to be easier to pull???????? Thank you guys some much but nothing helped.. :{ I think i will sell it for parts if i cant get it started :{ i want to ride so bad im only 16 and cant drive yet my life blows all i want to do is ride and this damn bike is holding me back every day after day!!!!! AHHHHH -JOE

now wire it the right way

[YTM200BOY]

i just said i cant i dont want to and i did enough to this pile already and my wiring is beyond different also my electric start will never work again.

[ebecme01]

It shouldnt be that hard to wire correctly. Take it to someone that has a Multimeter and knows how to use it. If it is now easier to pull now, you really should have a mechanic check it out. Dont sell it yet, you may regret it when the guy down the street rides it past your house!

[YTM200BOY]

lol i did that to the guy i bought it from lol he was so pissed all it need was a new plug aND I got it for only 75 bucks!! but i put about 350 in it!! I am not bringing it to anyone else and im not putting anything else into this bike!

does stable in the gas effect it??

[YTM200BOY]

forget the wiring guys! thanks also how much do * think i can get out of this if it starts?? i now it will run like a top once i get it started

[YTM200BOY]

lol my choke isnt on my bike anymore the idiot that had it last broke it off.
