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.

Mr Shadi

@SpookDog i also looked under the speedo and there is a white little box with blue and green red wire coming out of it. i tought it was a light but when i looked it had a little space between 2 metal thingies in it and it was covered with glass. Is that the reed switch?

Mr Shadi

@Mr-Shadi

SpookDog

@Mr-Shadi

I’m going to say yes. I’ve never seen one myself but it’s matching every description I’ve heard
You just have to move it away from the back of the rev counter/speedo clock and isolate it from them…

Do you have a rev counter and a speedo? Or just the speedo? I always thought that the reed-switch/bulb was behind the rev counter, but I could be wrong….

Mr Shadi

@SpookDog i have both. i isolated it with electric tape but it still dosent let me go over 80km/h and now the rev limiter can be heard. when i put in 5 gear it wount rev over 6k and same 6 th gear. and sometimes it dosent let me rev over 6k in all the gears but sometimes it does. i dont know what to do.

Mr Shadi

@Mr-Shadi i read the scrim derestriction guide but i am ether blind or there is no explanation how to move forward.

SpookDog

@Mr-Shadi

Have you moved the bulb as far away as you could from where it was? I thought it was behind the rev counter?
What country are you in? Is the bike native to your country? I’ve never heard of a dt125rn!

Try putting it back and seeing if the bike at least ‘settles down’!…

At least something is happening, even if it’s not what you want! It can (sometimes!) help to diagnose the problems …
