DT125R FORUM

@DTRLuke @dan28

Thanks for your help chaps.

Turned out not to be the Kickstand safety circuit!

Check the spark plug outta of the head and it was not sparking.

Turned out to be the wiring had come loose. I had to remove the seat and tank and get ready to start undoing copious amounts of electrical tape!

Once all tape is out of the way I found a big bunch of black wires terminated together! This termination looks to be standard from factory at Yamaha. It looks like a big blob of solder is connecting them all together.

To be honest it took me a while to finally figure out this was the fault as the connection looks really good and strong however there are so many cables in there and the connect was the problem.

Instead of re terminating the cables I tied a cable tie tight around the neck of the bunch and that solved the issue, Spark plug now Sparks!

Hope this helps people in the future !

@claws I had the same problem with my DT125X !!

Hopefully this helps and get your plug back sparking !!

Thanks for your help chaps.

Tried earthing the black and white cable no joy ! The. I removed the plug and tried running with it discounted and still no joy!

Just to be clear your bike is running with the black and white cable disconnected / earthed out to the frame!?

Thanks for your help !

Hi all,

I have an issue on my DT125X where it starts but as soon an I put it in gear it dies.
I’m sure it’s the kick stand safety Circuit. Traced the cables and there on blue and one white and black.

The blue is connect to anywhere circuit but the black and white is just left as a dead leg and unterminated?

Can any one tell me if this is correct?

Much appreciate
Mike

Hi All,

What carbs will fit the Dt125x?

I’ve damaged the original and need to source a replacement.

Really struggling to find any info on this so would appreciate your comments!

Thanks
Mike

Hi Glynn thanks for your reply and feedback!

I would be very much interested in the carb if you still have it! If so can you send me a few photos to wilsonmichael1992@gmail.com

Much appreciate and look forward to your reply!

Hi guys,

I ruined my carb on my Dt125x 05. The air mixture screw was seized and try’d using an easy out.

It did not easy out and I made a right cock up of it.

I’m looking at replacing the carb but the original was a MIKUNI running a 240 main jet. The carb did not have a model number on it.

I’m looking at the mikuni VM28-418 (TM28) will this fit a Dt125x???

Any recommendations on replacement carbs will be much appreciated. I was also looking at Nibb racing carbs ?

Thanks guys !
