If you find out something that i haven't got written in derestricting section then let me know and i'll add it to the site.

By the way, did you get a wiring diagram with the bike? (should be in the back of the owners manual if you've got it). It might be useful to help figure out what those 3 wires do.

I personally haven't looked round a "new type" (DT125RE, DT125X) as i don't know anyone who's got one. Therefore i can only base my knowledge of the electrics on what i've read about them.

hows it goin,top end of mine as i drove it home was 65 also,struggled to get there too!i seen the thread on the web and i actually double checked with my local yam dealer who just confirmed the same,its the green wire that dosent actually connect to anything,just earth it,thats all ive done so far ,now top end is about 80 ish!getting a full dep pipe soon,let everyone know how it goes then...cheers andy

hi there

is the only mod from standard you have completed - earthing the green wire?

LOCOINSANE · DTR Member

earthing the green wire is the only thing ive done so far,saving up for a full dep pipe and any other goodies i can get, thanks Andy

mrsmith · DTR Newbie

hi there,

do you know if the dt125x has the same wiring as the dtr?

did your yam dealer give u any other advise? how risky is it to remove the rev limiter?

does yamaha produce this engine on another bike de restricted? or is it possible de restriction could half the life of our engines?

LOCOINSANE · DTR Member

i hav`nt got a clue about the wiring,as for my yamaha dealer they are as much use as a chocolate fire guard,the only reason i use them is that ive got 2yrs warranty left on the bike. ive disconnected the rev limiter (i think )and it does`nt make much difference,must be coz im over weight,sorry im not much help,im gonna see if i can get a work shop manuel next week if i get one i`ll let you no,and email you what you need to no. thanks Andy

fastandy · DTR Member

the guy i got the bike from,rang the local yam dealer it came from,all he says you can do is the wire for earthing the powervalve,and cut open the front pipe to remove the collar/washer,or obviousely replace with a dep system!thats it

LOCOINSANE · DTR Member

is the wire under the speedo or is it located some where else and what colour is it,i got some info off the net the other day and earthed 1 or the wires,sparks started to fly and fused my bike,what a pain trying to change a fuse, thanks Andy

fastandy · DTR Member

its a green and black wire that goes nowhere!its in a 4 pin connector,but theirs nothing connecting it!just earth it on something,take off your headlight plastics,in behind it there not in the speedo

LOCOINSANE · DTR Member

i have a connecter box but only 3 going in and 3 coming out,i have the black wire but my green has a red stripe in it, and when i earth them both the temperture gage light stays on,

fastandy · DTR Member

sorry might be a green and red wire!anyway its a primarily green wire,but it is in the connecter,if you look theirs nothing it actually connects to on the other side,so just earth it,that should actually be all simple!

LOCOINSANE · DTR Member

its already done,its not making any difference,its only getting 60mph at a push,

fastandy · DTR Member

something not right there mate,wee bike should pull 60-65 when fully restricted,when youve earthed the wire should pull 70-75,but will hold top end a wee bit better

LOCOINSANE · DTR Member

any idea why the bike would be like that,something to do with the engine,

JHHUNT · DTR Member

Your bike should go way faster than 60 mph mine did 75 fully restricted!earthing the green wire 80-85 ishstill waiting for my dep exhaust, my old one snapped off!

have you tried cleaning your carbs out??

LOCOINSANE · DTR Member

do you think it could be the powervalve not set up properly,maybes its still on factory setting ,i just dont no

JHHUNT · DTR Member

Try turning it round. My mate did that on an older dt, not sure which model but it went like sh1t off a stick after

JHHUNT · DTR Member

Are you sure you have derestricted the cdi properly by earthing the green wire with the red stripe on??

LOCOINSANE · DTR Member

i bort sum information off ebay and it said to earth the green and black wire,after several hours i found that wire,at long last,so i earthed it to the frame,its seems to have nocked the rev limiter off but does`nt go any faster,thats why i was wondering if it was the power valve setting

shaunpearmain · DTR Member

nah mate it wont go much faster, mine did about 60-65 70 at a push, now with just the wire earthed it does 65-70 75 at a push so its not much different really, but it does get there quicker and has more pull in top gear.

i doubt its possible to do over 80mph on them without a gearbox/sprocket change for top speed

edd · DTR Member

mine was green and black on 125x just earthed it to the bottom yokes, 70 standard and 80 with the wire earthed and 85+ with full dep sport. standard gearing

Davie139 · DTR Member

what year was your 125x edd? So is the powervalve hard to change yourself? and should it need doing on a new 07 dt125x?

DIABLO · DTR Member

on my 05' dtx the wiremod derestricts the powervalve

LOCOINSANE · DTR Member

how can you tell the powervalve is deristicted,do you still get the powervalve making that sound when you turn the key in the ignition,dont no much about the DTX,taking the air snorkle from under seat does give a little bit of a power increase,quite suprised, thanks
