Derestrict yamaha dt 125 r 1997

[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.

[Mr Shadi]

@Mr-Shadi i searched for wiring diagrams and i found one very pixelated one that showed the reed switch and its just 2 wires that go in to the cdi with nothing in between and there were 18 wires.

@Mr-Shadi

Any progress?…

It is weird that it activates if you move it away from its spot. Are there any other wires going into your speedometer apart from the read switch ones you’ve mentioned, and the two for the bulb? (blue & black on mine) I’m wondering if the ‘activator’ in the speedo is electrical or magnetic/mechanical in some way…

@SpookDog I GOT IT! I derestricted it. It took me a long time and a lot of anger but i DID IT! I did it by cutting the reed switch wires and putting the reed switch in its place with exposed open wires. Then i turned the bike on and kickstarted it, after that i revved till it hit the rev limiter and connected the wires till the rev limiter passed 6.5K without staying stuck and taped up the wires so they don't touch (Not the wires that are on the reed switch. The ones that come to it) and put them away. now the bike accelerates beyond 80km/h 50mp/h.

@Mr-Shadi

Sweet! I’m happy for you bud …

@Mr-Shadi

So disconnecting the wires while the revs were above the limiter somehow reset the CDI?…

@Mr-Shadi bloody hell mate, if you scroll down through this thread you'll see that's exactly what I told you to do back in April. Glad you finally got it anyway. Happy days.

We’ve all got bad memory mate, goes with being human …
If I don’t write things down I end up doing crazy spinning circles 🤩

@markus-w
You told me to cut the wires and keep them apart lad. That didn't work, what i did was i cut the wires and connect them at the right time to somehow bypass the restriction.
