Yamaha DTR 125, fell over, now it wont start!! HELP!!

[P3TR0L H34D]

Hi everyone, Im new to this forum so be gentle with me lol.

I bought a Yamaha DTR 125 yesterday, its a 2003 and has apparently recently had a top and bottom end rebuild. So one would presume it is mechanically sound. I witnessed it riding and running when I bought it, then during transportation it fell over and was laid down in the back of the van for approximately 2 minutes. I opened the van doors to quickly pick it up and there was a small amount of petrol on the floor (which I'm not sure where it leaked from) and it wouldn't start. So I have left it sat until today, unsure of the problem hoping it would start. Unfortunately it hasn't and from trying to start it franticly I have almost zapped the battery, making things worse lol. I have tried to bump start it and it wants to but just will not start! I am not new to bikes, but don't have much mechanical knowledge when it comes to fixing them/standard issues that would be obvious to someone with experience. I hope this is a simple issue and would be REALLY happy if someone could help, thanks for reading and hopefully I recieve a warm welcome on my first ever post.

Turn the petrol tap on and try again

I've tried relentlessly and it just wont have non of it lol, usually when my bikes have behaved like this, it's because their flooded but this doesn't seem to be the case. It's REALLY frustrating because I've seen it running lol

[jack_p92]

carb maybe flooded? is there defiantly petrol in the tank and 2 stroke in the oil tank?

Is there spark? HT lead still connected?

Have you taken the spark plug out and had a look at it?
Have you checked you get a spark on it against the head?
If not THAT'S where you start.... after charging the battery!
If no spark, you check the obviouse first.
Kill switch on the handlebars, and wiring too.
Side Stand Switch, & wiring to
Ignition switch & wiring too
Then you look at the fuel.
How much fuel was in it when you collected it?
No one fills a bike with petrol just before they flog it these days!
Might have had enough in to run when tested, but falling over, that 'small' amount of petrol might have been ALL that was left in the tank, not just what was in the carb float bowl!
Have you checked how much fuel is in the tank?
Have you tried it on both 'On' and on 'Res'?

check the side stand switch if applicable, kill switch, ht lead is located correctly, all connectro blocks are connected, fuel tap is on/reserve if you've spilled you petrol out you may have dropped below the ON required level.

Once You've checked what the guys above say. If that fails....take out spark plug. Pour a little fuel down the hole using a funnel say 50mls and put plug back in make sure ignition is on and kick her. If you're getting a good spark this should make it fire.

Does it have choke? You might want to try putting that on.

There is a lot of nonsense in this thread.

I would do the following:

ignition off

turn fuel tap OFF

locate carb drain screw and drain the float bowl on the carb.

Remove spark plug and examine

kick bike over a few times with no plug in and the fuel off. See if fuel is ejected from the plug hole.

connect plug to plug cap. Switch ignition on. Holding the plug cap, hold the threaded part of the plug against the head or barrel so you can see the electrode.

kick bike over and see if there is a strong spark. If not replace spark plug.

Re fit spark plug

turn fuel tap to PRIME for a few seconds

Switch fuel tap to ON

attempt to start bike using a bit of choke.

If this does not work, you will then need to check that fuel is getting to the cylinder. This is a bit more complex if the bike has a vacuum operated fuel tap...

All good ^^^^^^ except I'd hold the plug cap in a pair of rubber-handled grips when checking for a spark by holding the electrode to the barrel and kicking it over. You don't want to find out the plug cap is cracked when holding it with your fingers. That really hurts.
