Derestrict yamaha dt 125 r 1997

[Mr Shadi]

@markus-w i can hear the spark plug not getting spark when it goes above 80 km/h. But it takes a a little while for it to start not getting spark (3 to 7 seconds). And when i disconnected one of three cdi wire connectors and went on the road to try again. The restrictor sound was different and started right after 80km/h with no delay, unlike if the connector was connected.

@forum members
Isn’t there a later model that needs a CDI wire cutting & earthing somewhere? Or is that a Tzr?…

I’m sorry Mr-Shadi, I don’t know too much about later than 1995 model dtr125’s, other than what I have read. What country is your bike from? I’m guessing that english isn’t your first language?
I’ll do a bit of reading and try to find out about 1997 bikes…

Edit: 4dl Germany! Got it!

The DTRE has a green and black wire, once earthed that's all the electrical restrictions and then the bike revs off the clocks.

@Calum

I’m worried that he might have the one with the ‘silver box behind the 2T oil tank’ that needs loads of faffing about! I tried getting scrims guide up but kept getting a 401 error!…

[Calum]

@SpookDog 401? That's Unauthorized

Right, yeah I don't know about that one. I only really researched the one for my bike.

Best thing to do is get a Zeeltronic ignition system for it and you're laughing.

@Calum

On a copy (of scrims) on another site it said to install an earlier CDI I think? Yamaha certainly had it in in for you lads with later bikes! Access Forbidden! SNAFU! ️ …

My bad! It was 404 not quite as verboten! …

[Calum]

Yeah that makes more sense 404 - Not Found. I think you'll find 403 is Forbidden @SpookDog

[Mr Shadi]

@SpookDog i don't seem to have a silver box behind the oil tank. The only silverish/grayish box is the voltage regulator.

[Mr Shadi]

@SpookDog scrims sites hosting server has stopped broadcasting the info. But there is a slideshare link on the forum that has the site in slide form

[Mr Shadi]

@Mr-Shadi on the way back machine, its possible to see the old dt 125 net and other sites but not a lot of info on them

[Mr Shadi]

@Calum i just bought the bike so i have no money to buy a 300 euro cdi. Trying to do it for free

[Calum]

@Mr-Shadi Sure, but some models of DTRs were heavily restricted via the CDI, so you're literally gimped until you replace it with either a less restrictive CDI or an aftermarket one.

[Mr Shadi]

@Calum ok thank you for the help. will save some money to buy one then

[SpookDog]

@Mr-Shadi

Seen a few 3nc’s on eBay lately for reasonable prices. I got one for about £30 a while back…

Still not convinced you need one yet. Try and find a copy of scrims write up. I found one the other day, I’ll try and get an address…

[Mr Shadi]

@SpookDog i searched a bit and found my bike is actually yamaha dt 125 rn 1997. The rn model is restricted to 80 km/h and there is almost no info about that bike.

[SpookDog]

@Mr-Shadi

That’s not even 60mph! Damn! I did think that you might have one of the’stranger’ ones. I still think that scrims deristricting guide is your best bet…

[Calum]

I'd just get a Zeeltronic and be done with it.
