@Mr-Shadi
That is weird! It’s good that you’re experimenting with it…
I think that you might have the one that needs a CDI wire cut and earthed. I’ll try and do some reading and let you know …

[SpookDog]

Look for a green/black wire on your CDI unit. Let me know if you find one…

[Mr Shadi]

@SpookDog i dont see one. here are some pics 

[SpookDog]

@Mr-Shadi

It might be a different colour on account of the weird RN thing…

From what I’ve read people move the reed switch then cut & earth a black/green wire…

[Mr Shadi]

@SpookDog i think if i take the other bikes wiring diagram with black green and then my wiring diagram and then determine witch wire does what. like compare the wire colors for example its bike has red wire as power mine has orange. just a example not reality.

[SpookDog]

Hang on bud! Your bike is a Dt125RN you said? Did you mean a Dtr125 3rn? This would make more sense!

[SpookDog]

Just counted CDI wires on the 3rn diagram in my Haynes manual and it says 11 wires from the CDI. How many have you got?…
I’m just curious cause it doesn’t show the reed switch or any wiring to the speedo on the diagram, guess they wouldn’t show the restriction though! …

[Mr Shadi]

@SpookDog it has 18 wires. 3 cdi connectors with 6 wires each.

@Mr-Shadi this is a reed switch. If you look at it, it looks to be a broken fuse. When the speedo hits 61 mph it sends an electro magnetic signal and closes the switch which retards the ignition and closes the powervalve back up. Either move it far away from the clocks so the magnet can't reach it or cut it off and keep the wires apart.

[Mr Shadi]

@markus-w if i cut it off the bike wount rev over 6k and if i move it it randomly restricts it to 6k rpm. then i need to come to a stop and it revs over 6k.

[Mr Shadi]

@markus-w and my reed switch allows me to go only 80km/h thats 49.7097 mph

[SpookDog]

@Mr-Shadi

We need to find out what wires need to be cut and earthed. On my tzr 4hw there are 2 wires that have been cut, joined and earthed by previous owners. A black with lavender-blue stripe and a grey…

[Mr Shadi]

@SpookDog that would be the thing if there was a good electrical scheme of my 4bl 1997 bike

[Mr Shadi]

@Mr-Shadi in one of the manuals there is this

[SpookDog]

I’ll look for a 4bl (I’ve never heard of a 4BL, you sure it’s not 4DL?) wiring diagram…

It is bl just checked

[SpookDog]

What colour is the wire going to the reed switch? Also what colour wire returns from it, if different?…

is it red/blue?! with a white/black wire returning?!

[markus.w]

@Mr-Shadi you have the 4BL model, that's the later one with the reed switch but I guess you must have the restricted 3RM-10 CDI?

[Hybrid_Theory01]

Hey guys, my CDI has 2 plugs with like 4 wires coming out and plugging into themselfs, has anyone seen this before or should I send a picture to this chat? Its at least weird but Thats how i bought the bike

[Mr Shadi]

@SpookDog sorry for not being active i had stuff to do. yeah its a 4bl not a dl, if u google 4bl this bike will come up and its exactly my bike and the reed switch i already drew it was green/red and a blue one

[Mr Shadi]

@markus-w it has a restricted cdi but its weird that if i move the reed switch at all it dosent rev over 6k. and i was thinking if i cut the wires and leave the reed switch in its place without the wires, maybe it will work.
