DT125R FORUM

@madgyver thank you, I will look into this

I always looked at getting a direct original replacement, as I knew they worked and mainly because a couple years ago they were cheaper than the custom ones. However, now its tough to find an 11 pin for a reasonable price, which is why i'm considering other options. As long as a CDI fits and runs unrestricted I will be happy with it. Personally I preferred to run my bike without the PV plugged in but that is a big feature of the bikes so finding another 3 pin compatible one is a big factor.

@calum I wish I could say the same about mine, but I think I just got unlucky with the electrics of the bike. Not to say I didn't have some fun on it, at the time it was an amazing bike, but after sitting for so long without use, I feel like its potential is higher with someone else.

@hotshot-iii Thanks for all your advice. Before i went to uni I had had checked over the whole bike for all the points you mentioned. I took a multimeter and checked the HT coil, the end of the lead, for resistance readings, same with behind the flywheel, everywhere where the manual specified for troubleshooting no spark, and they were all within required ranges. I inspected the loom for exposed wiring/shorts but found none, and checking for continuity gave me no anomalies. It's after checking all this I asked on some Facebook groups for advice, and some said there will be a buzzing white box underneath the seat, but my model didn't have that. Some suggested it could be a faulty regulator, and turns out my bike had an aftermarket one on, so I replaced it with an original and ordered another CDI (when you could still find them). Now I will admit the installation of the last one was the reason I think it went; I didn't make sure the CDI was grounded properly and partly blew it. There is a weak spark when I kick the bike over, but not enough to start the bike or keep it running when bumping it. Considering that all other aspects of my electrical circuit seem to be fine, I am inclined to think one last CDI will finally awake the bike again (when grounded properly!). I did see that German one you have linked, and last resort I may get it, I also want to bide my time and see if any will get listed for the prices I used to get them for (70-120).

I would love to keep the bike but its MOT has expired, and unfortunately i don't have a homologated exhaust for it anymore, which I'm sure would be easy to find, but whilst at uni its tough to keep spending money on it, let alone time, so I think I need to part with it so someone with the time and money can give it the tlc it needs. I just don't want to sell it in a non-running state, as advertising it with a blown CDI isn't exactly a great selling point lol.

I have a some mates with 450s, and I have heard their stories about their issues, but it is more of a long-term goal to move up to one for me. Whilst I spend so much time away from home I don't think its practical buying a bike for it to sit, my reasoning behind selling my DT too. Unfortunately i have plenty of parking space but nowhere inside, and cover storing a bike for years doesn't sit right with me.

Hello everyone,

My bike liked chewing up CDIs. I believe the voltage regulater went some time ago, unbeknownst to me. This blew two of my CDIs, after which the regulater was replaced. A third partly blew after a faulty ground connection. The bike used the 11 pin 3NC-00 CDI, but I am having trouble finding any online for a sensible price. I researched the post made on the old forum, looking at the interchangeability of other CDIs from other models.

Before I decide which CDI to hunt for I wanted to ask if anyone has successfully changed over from a 3NC to a different one, how it worked, any issues etc.

TIA

hello @Calum, this is an old photo and there are few more things to it than meets the eye lol. I'd rather it go to someone who could make it nice too, as being at uni means I can't spend as much money on it as I'd like to. I'm also looking to upgrade to a 450cc at some point, hopefully this bike will help me achieve that.

Hi guys, I'm adrian from the UK and I own a 1998 dt 125 r (at least that's what the logbook tells me).
Mine is the filthy one in the foreground I'm actually trying to sell it now as I have gone to university, and i will be making a post later in the electrics subsection to query its fault that's preventing me from selling it.
