Why Wont It Start Ah!

[DeePa]

man you gotta relax and take it slow. Buy a new wiring harness off of ebay and start from there, and youll start making progress.

If you ripped wires out of somewhere, dont tell us to forget about the wiring.

Keep your head up, itll all work out, just stop spazzing and posting 15 times a minute with no new information

dont sell it just because of this, hahaha ive pushed my bike a mile home, and rebuilt the carb, and resoldered all conections, and changed the chain all in one day, because they all wore out.

you have it good.

anyway, follow what everyones said. use some starter fluid/gas into the cylendar, try to start it. if it starts, then you probably have a problem with the carb. work from there, and take it easy.

Hold up ---its easier to pull?????? Your crank key is busted off------Rotor spins -Crankshaft doesnt- Put your finger in the spark plug hole==Does it have compression?

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_

Dude,
go outside , sit next to your trike, take a deep breath, calm down, and think...."it was running fine until I did what?" Start with the very first thing you worked on. Go over it, make certain it was done correctly even if it takes hours. will it start? no? now go over the second thing you worked on, does it start? keep doing this until you find the problem, I will almost promise you its something you overlooked!!!!! and probably something very simple...I worked for an hour once trying to figure a no spark problem...my kill switch was off, go figure

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.

anytime you say you "cant" do something, you never will! My grandmother is 90, she always says she "cant" an she never does...just rocks in her chair all day. So whenever you hear someone pass buy on their way to a riding spot, dont ever wish it could be you......... because you "cant".
As far as wiring goes...use the diagram someone linked...it doesnt matter what color the wires are , just wire it the same way it is in the diagram...follow one wire from a start point on the diagram to the stopping point..is it the same on the trike? do this for each wire, until you do the all....if it isnt the same, then put it that way....You have to try, YOU have to WANT ...its the only way..Dave .

Clean the carb and make sure everything is adjusted right. Once that is all done we can move on to more "technical" whichamacallits

You guys are inspiring thanks its not for sale i will get this great bike working again!! i no it. my dad's buddy rebuilds stuff and cars to oringal hes coming over saturday!! i dont think i broke a wire because my dad said its getting spark :}

[Dave223]

ok its getting spark, so now you need to other things...fuel and compression
try putting the plug in an spinning it over...check the plug, is it wet? try a few drops of gas in the cylinder an spin it over...does it want to fire up? try these things an tell us what happened

[ebecme01]

No, fuel stabilizer wont effect it. Try the good plug, starting fluid, and youre off. Engines only need three elements, compression, fuel, and spark. You say you have spark, assuming its timed correctly, you just need to get fuel working right. If you put your thumb over the spark plug hole and pull or kick it over, if it blows your thumb off easily, you should be ok. So, try squirting a littel starting fluid in the cylinder, put the plug in and it should fire.

So did the bike run after the 50 dollar hob wiring job? I guess you changed the carb piece after the wiring was done?

You need to go back through your work because if you haven't rode it something you changed is the problem.

[traxxasx]

well if it ran before the new "float valve" change that that is 99% ** problem, i mean come on if it ran then * changed somthing and now it doesent........that makes alot of sense into why it doesent run???? right>?

[YTM200BOY]

i tryed the starting fluid idea what can cause this key to break off or whatever your talking about and where is it at??

[YTM200BOY]

the old float valve has no tip it blew off some how so that float valve is shot i threw it out now i got a new one and i thought once i installed the new float valve these bike would b ready to ride and cont wait until the float came.... Now blah lol..

[YTM200BOY]

carb is clean

[YTM200BOY]

does any1 else have ideas?? for the peopel that tried to help thank you again --JOE
