DT125R FORUM

@DTR-NSR

I haven’t gotten my head around it yet 🙂 but that was my impression…

@Markk
I wouldnt bother with the DT motor unless you really feel the need, they are better lighter smaller kart motors available for the job. It would be a chew on setting the chassis up with the gear box drive position then your looking at seating position exhaust gearing brakes etc etc. Having taken my son Karting from an early age and spending thousands on bambino and cadet class and that was just for fun at weekends not going down the racing route, The 125 is a different league and bigger financial pockets are required. It’s a nice thought but unless you're chassis builder and have access to a workshop I just wouldn’t go there. But if you want to do something original as a gimmick which you’ll never get an MOT for and the Feds would crucify you if they caught you on anything that looks remotely dodgy. I’d just leave well alone IMO.

Thanks for the reply, karts built, we do have a workshop/fab shop etc. The karts just a toy for my son who learns by building them. This one is a different beast and has defo been a challenge. We have done a few test days, indoor and outdoor and now we are just ironing out the niggles like YPVS not working above.
Does the CDI regulate/rectify the generator output itself?

Did you resolve this issue a while back?

@HOTSHOT-III

Damn, I was kinda hoping it was just me. Then it’d be fixable! 😜
I brought a rectifier for a later yam cause I thought mine looked like a fleabay job replacement. The connector block is slightly melted on the loom side, so I thought the old original one had suffered a meltdown!...

I’ve had a few different bulbs and I think they all do the dim, at least the halogen ones. It was just more noticeable when I had an Osram night breaker fitted! Can be bloody scary & dangerous sometimes when it dims while the oncoming dipshit with the HID bulbs is dazzling you with high beams! 🤨

I wish I understood electrics better than I don’t 🤪

@HOTSHOT-III Yeah, I only use Linux and Firefox.

@Calum I'll give it a look thanks mate

@markus-w Hi markus, thats very kind of you, i have found a screengrab of the wiring online, i have also managed to get a spark from the loom (whats left of it) unfortunately, the whole ignition has been bypassed so it will run without any keys, but at least i have a spark! Also thanks to callum for fixing my links.👍

@dan28

It changes from light blue to blue according to Haynes manual. Only change I can see. Don’t take the wire placements literally on the diagram. The wire colours don’t align to the plugs...

Is there a problem with your neutral light or were you just wondering about the manual? Cause the manual (bless it’s cotton socks) is full of fekin mistakes if you look long and hard enough. I thought my bike was supposed to have a 26mm flatslide! 🙄 ...

I’ll definitely put a decent one on, probably off of a late model Yamaha 125 with a 9 amp battery. The one I have on is a cheap replacement, judging by the plastic connector and cable quality it’s Chinese 🙄

@spookdog said in Kill switch doesn't work:

I thought only electric start bikes had them though

It's a DTX (2005) so yeah, it has electric starter.
Ty for your answers. I hope that this post help someone else. That's the point of forums 🙂

@dan28 no, assuming you mean the level sender in the oil tank, you can just unplug it and the bike will still run fine

@yannikmeister thanks for your help I found out why indicators not working the relay box had been snapped off just leaving connection and no box and yes it was behind the headlight cheers

@calum alot of money is 100-150$ bcoz if i want sell bike no one will give me 300$ for bike..

I have cdi but need diagram for it.. I think u can help me.. Somethimes i get spark if i tap black wire from cdi to ground on whitegreen from stator.. If i keep no spark only when i fast tap i get spark

@spookdog it's an entire unit so completely different

@calum lol funny you say that when I turned the bike off I could hear the battery acid boiling, weird thing was the battery was cold to the touch all around,it's definitely something to watch out for no warning signs until it's too late luckily I had the multimeter hooked up the whole time so I knew it was over charging

@walney-reptiles The servo opens at 6k to 9k and should be fully open at 10k.

So just because the bike is running, doesn't mean it's actually operating.

Not sure if the neutral switch tells the CDI not to operate. In other words, it has to be in gear and past 6K to operate.

Could be goosed, but again, just staring at it isn't going to make it move.

Put the Yamaha part number into Google / Ebay and try looking at various different countries around Europe (do this in settings).

@edfrearson

The tripmetre knob unscrews clockwise...

Search ’dtr carb’ on eBay

@crispy yeah I know about the starter I was just referring to motocross bikes, if it spits your finger off it's probably good
