C.D.I. UNITS

Mugen Seiki · Guru

If you change the CDI the wiring loom will have to change aswell , headache imo

Earlier Dt's had the unrestricted CDI's , pre 03 I think .

Your CDi is NOT restricted ....

None of the 04 to 57 bikes were [RE .. X]

Just the wire to ground out to activate the PV over 6K & exhaust needed ...

Bike will rev out [like many of the guys here] and fly off the clock !!

80 + easy ... on standard Cdi ...

Bordering on 90 mph downhill ... is deffo not restricted for a 125 2T trailie !!!

i dont think you understand what iam saying so what is this doing to the bike by earthing the cable where does this cable go and ive already done this derestriction and i recon by doing this its shorting the cdi causing the restriction to go

Daft question ...

But you got the right wire yea ???

The http://dtr125.net/tuningf.htmW used on these bikes is a simple one to fix:

Going into the speedo is a four pin connecting block. There are 4 wires going into the block and only 3 wires coming out the speedo side. Just find the Green/Black wire going into the block, clip it to separate it from the block, and strip the end and join a small piece of wire to it (long enough to to join to an earth on the frame). When the Green/Black wire is earthed to the frame this stops the YPVS from retarding over 7000 RPM. The engine should rev freely now.

yes mate i got the right wire it was working as my bike was alot quicker after i done it as it revvs freely.. what i was saying is by doing the earth its completeing a circuit and maybe shorting the cdi unit frying the restriction which is electronic therefor it is no longer restricted it would make sence because im having electric problems and a lot of other people that have done this are also having electric problems but none are the same eg my pv dont work my m8 that has done this his left indicaters dont work and a coupple of people on here are having electric probs and they have also done this earth cable but i ant no expert but its lodgical

tbh mate i think you must be doing the wrong cable if its f*king the electrics up as all my mates n mine have had no electric problem whatsoever

born2race · DTR Senior Member

really fair doos i defo got the right cable the green and black 1 i think but i know its the block that has 4 cables going it to it and only three cuming out and you have to chop the 1 that goes no wea and earth it and it must of been the right 1 because there was a increse in power
and i ant being funny but i ant a silly 1 lol
