DT125R FORUM

Hi
Does anyone know if a dt 125 r engine will fit in a dt125x frame?

@SpookDog
The bike is a 2007 model

@Calum
Hm yea. The side stand switch is zip tied closed so unless it’s faulty i think it’s good. How do you loop it?
Ignition switch is from another DT I have, so I know that is working.

Hi.
I recently bought a Dt125x/re yesterday.
When I checked to see if it was spark, it only sparked once, and then it disappeared. It seems like it only sparks at one revolution.
What could be the cause for this?
Any ideas‍️

@SpookDog
Yea I know, but I have a local shop that’s got all kinds of bearings and oil seals. So I just wanted so see if they had any who fits my engine. Then I don’t have to wait for delivery and etc. But do you know which ones come originally?

Does anyone know what the right crank bearings is for my dtr? Is it 6305r1? Same for both sides?

@james
Thanks for the tips!
I have a spare engine that I will swap it with in the meantime.
Thanks to everyone who have helped!

@SpookDog
Hmm yea, I took the woodruff key out, and it looked good. Maybe I just have to start taking it apart

@SpookDog
Hey.
The I tried to rotate, and it feels like normal. Nothing crunchy or anything. I also tried to swap the clutch basket out with another one I had laying around, which I knew worked when I took It off. I started it up and with no luck, same vibration

Yea I also saw the @thing haven’t seen it before.

@Calum
No, all are tight and good!

Hmm yea, maybe it could be the bearings, although I changed one of them last winter, I know I should have changed both but I only have one Yea, all of the nuts were tight and no loose nuts

Sorry for the late respond.
It is vibrating even when I stands still I neutral. Could it be that’s the bushing are the cause? Or maybe something else?

I looked at the balancing shaft and the crank, and the 2 dots line up, I know that is fine.
But the cog itself has play from the basket if you get it xD
I’ll trie to post some pictures.

When i was riding today, all of a sudden my bike started vibrating like mad. And it seems like it won’t Rev up. I checked the balancing shaft and flywheel, which all seems fine. However the clutch basket has quite a bit of play between the actual cog and the basket. Could this cause mad vibration? Or what else could?

@SpookDog
Have drained the carb multiple times,
No water and stuff

Hmm, could be the crankcase seal.
But it is on and off. Sometimes it bogs down, and sometimes it doesn’t. I took it for a little ride now, and now it was fine.

@declan

Already cleaned it, everything is fine

I tried to spray some brake clean around the intake, but it didn’t make a difference

When I let go off the gas it sometimes revs up really high. False air maybe?
