DT125R FORUM

Hi, happy new year to everyone!!

Can anyone tell me the scheme for connect the DT50 CDI with DT125R Stator ?

i want to keep the DTR CDI working for the YPVS and the DT50 for the ignition timing

so, working with 2 cdi's, the DTR only for YPVS and the other controling the ignition ( spark)

I want to do that, becose the 50cc have better ignition curve and no limit for rpm, and i want to keep the pv working

A few years ago btw i see a scheme for how to do that but now i can´t find that again...

ps: sorry for my not good english. but i can explain better if you dont understand properly
Thank you all

@nottsbiker im from portugal, and the dtx forks + hub ( or complete wheel ) are very very expensive

Hi there!

I have a DT125 RE with a oem fork, but 17"17" wheels ( DTRE\DTR HUB)

But i want to put a 320mm brake disk.

Any ideias for a disk plug-n-play on the DTR hub?
How do you guys do it ? and the caliper suport ?

Tks

Or other hub\wheel solution 17" that fits in DTR oem forks

@calum the ignition curve on DTRE changes when you make earth with black\green wire ?

i already have that done... but honestly i dont feel diference between that...

@goprokid95 I know that... 2004 bike, the crank its diferent, and the stator fits in the engine cover.

i already try the DTR 2002 stator in a 2006 DTRE CDI unit it works, but no reving mutch.

i run 35.000km with no problems full stock bike \ all eletrical working since factory.

i already make som mods on my engine... my bike was one of the first bikes with 200cc kit in portugal. i let the youtube link here

https://www.youtube.com/watch?v=oPKfwwHDOKQ

But now i want to put the bike full oem becose the police....

i have 2 engines, 2 eletrical systems

1 complete swap from a 89 dtr

1 complete swap from 2005 DTRE ( thats my blue bike )

so my problem its the 2005 DTRE Stator burning...

As i said i try diferent ways to run the 2005 swap ( oem Bike swap )
the stator is burned like i said. And i try one other stator from 2002 DTR (from other bike)
I make some adjustments to fit a 2002 stator on 2005 engine, it fits realy fine, the wires i connect color with color and it runs, but dont rev mutch (im thinking provably its out of timing)

aniway im thinking, maybe the best solution is rewind the oem 2005 stator (Source Coil)
Do you guys know a place to do it cheaper, or maybe know how many counting turns have the source coil ? tks

@calum Sorry if i express myself bad... or for my bad english...

i make that "frankanstain" after i burn the oem stator...

i want the bike with full oem eletrical system......

i try other stator ( 2002 ) just to see if was the CDI broken or fryed...

I want to work a complete 2006 loom, stator cdi, pv etc...

but my issue its the stator bobine... i have heard a lot of people with this eletrical version 4FU with the same problems than me.... that's why im triyng to solve the problem... or maybe found the reason to the eletric stator burn....

the pick of the 2002 and the 2006 have the same meseurments ~288ohms

the rest... the 2002 have 6 bobines 3x2 = 6
the 2006 have 15 bobines 3x5 =15

I dont know the retard\advance timings on oem eletrical system...
Anyone kwons that ?

GoProKid95:

I want to run the bike with 2004-2007 complete oem eletrical system, as a stock bike
but it gives me a lot of problems with the stator... i already see in other foruns like Yam2stroke (the french one ) and the (ClubDTR125 Portuguese one ) and other internet pages talking about the same relative problems.. its the fat bobine, the large one..that bobine its only for produce spark on the plug. i have think on rewind ( repair the fat one ) and see if last a litle bit longer....

@goprokid95 At this moment i have that setup out of the bike.

Today i have a 1992 engine with 1992 eletric instalation complete. all works fine.

I take out my OEM 2006 Eletrical system becose can't have the spark...

In first place i have the complete 2006 OEM Eletrical instalation without cuts and missing things.
then Burn 2 eletrical stators... allways the same problem... no spark!!

i try a last time, i simplefyed the wiring loom, put a new stator and it run fine, like about a 1 year, then fryed again... same shit... no spark!!

Then i try a 2002 Stator + Flywheel on my 2006 CDI Wiring Loom... ( losing eletric start )
I join the wires color by color, it charges the battery fine, it have good blue spark.

the source coil on the 2006 stator have 3 wires, 2 green and 1 black.
the source coil on the 2002 stator have 2 wires 1 green and 1 black.
i join the green ones and connect, it works but...

dont rev at high RPM's.... it feels like the ignition its out of timing... maybe too advanced, maybe too retarded.. i dont have a comparative gauge or a timing pistol to see that....

the bike with that setup, feels the low rpm very powerfull but on hight rpm its very slow to climb... on neutral runs fine revs fine... when i drive its slow making hight rpms... it feels like the powervalve its closed.. but i try with the pv locked in open position and its the same thing. not problem on powervalve.

and i quit of the 2006 CDI Wiring because i have the complete 1992 engine and wiring cdi etc... and i put all of that on the bike.

but i want to continue with the eletric start ant the original OEM Eletrical sistem...

anybody kowns if yamaha dealer seel the Source Coil separate from the eletrical plate ?

my thing its to see if a 4GX yamaha Stator from TTR225 or other stator like from Yamaha Majesti fits there... becose the Aliexpress and Ebay got that stuff cheap... 20x cheaper than the OEM DT125x stator...

@spookdog

Yes my bike its a Dt125RE I have the wiring loom simplefied only the essential, but connected properly by the orther of eletrical diagram.

Every thing works fine, all the resistences are ok... Everything runs fine, but I dont know what's happening... Its only the source coil fried out... Its for the spark

Hi, im new in this forum. Sorry for my not good english xD

But I have a question about electrical sistem of a Yamaha dtx125
I have one of that series bike, but its the 4 time that I buy a stator for it
Its that normal?? 1 year and the stator burn... It costs arround 600€ on yamaha...
Im tired of wasting my money on electrical stator with no guarantee by yamaha dealer. Do you guys solve the situation of burning stators how??
Do exists a stator that fits on my bike without beem the oem one ( 4fu) ?

I have seen the Traillway ones, and the majesty 125, and others.
Aliexpress and that have them new at good price. But I dont make sny idea if they fit on dt flywheel or even if the resistence values are the same...

Can you guys help me??

Im almost losing my head with my dt125re..... One more of this thing and I put the bike to recycle or whatever... Bad luck to me...

Sorry once again for my bad English.
I hope you can help me. Thank you
Rest of good day
