DT125R FORUM

@HOTSHOT-III damn just did enduro on sunday and the bike shut off instantly its having electric problems im having a very weak spark the bike doesnt turn on at all tried bypassing the killswitch and the kickstand switch no result and now i want to check the pickup coil from the stator im not that good with electrics but im trying my best to find the problem

@Calum ok, thanks, and what about electronics?

Cool build bud, where did you get the pipe from?

I’ve had someone listen to it as in person is obviously way better then a compressed video and think it may be the piston rings

@gary76 i do have the meter but i dont really know how to use it could u help?

That's normal. All DTs are like that. [image: IMG-20251011-114625.jpg]

@HOTSHOT-III Hopefully the issue gets resolved as I don't want to lose the data they're hosting. The important stuff I ought to host here to guarantee it isn't lost.

@HOTSHOT III Thanks for the reply bud yea all good on that front it’s the long pedal travel I don’t like it’s just me and how I like things

PS Same issue, bottom of gasket is dry and the top has oily wet channels…

Trust me, I love my RS, but the DT is just a solid whip. I now have an RS powered trail bike. Never ridden it, despite having it 4 years.

@Calum https://gilimoto.com.br/products/tanque-modelo-dt-200-r-possibilita-uso-de-aletas?variant=43453664133336 They have IT on ebay too https://www.ebay.com/sch/i.html?sid=gilimoto3402&_pgn=1&isRefine=true&_trksid=p4429486.m3561.l49496

@Calum thank you buddy appreciate

@HOTSHOT-III Thanks bud time to put up for sale now done

Thanks mate, will defo look into the impact wrench. I was just hoping it was going to be a quick easy fix with the bits i already had purchased and was shocked to see it was completely different to what i was expecting. My bike is off road due to an accident and im moving house in the next week so the pressure is on as i have no transport for it. All the best

@HOTSHOT-III Absolutely spot on information here. I've not had the thermostat fail on me, but MY GAWD does my DTR run hot. I am not making this up, my Vespa runs cooler than my DTR. The DTR could seriously benefit from a lower opening thermostat, especially when you tune. I've removed my thermostat and now the DT runs a cool 60 degrees. But you're absolutely spot on about having pressure at the cylinder head. It is stops pockets of stale gas forming causing hot spots on the cylinder head (promoting knock).

dont buy from ebay. buy from pjme. the bearings shouldnt of failed. were you running it in or caning it? did you make sure only to use the outer edge of the bearing to drift it in? if you pressed against the centre race it could of distorted, even dented the balls giving it a very knoychy feel...

I’d clean the carb. Also post info about the colour of the spark plug…

Couldn't resist in adding a few carbon fibre touches here and there.... [image: BXhtkSW.jpeg] I found a very nice Tomas Compitsite flywheel cover and fan shroude combo. As well as a gear selector cover and a spare wheel cover. Sadly, the other two items have not arrived yet.

Yeah it's worth checking that first. I haven't done a set of DT cases for a while, I've never done 200 cases.

@SpookDog Hope you're well bud? https://www.ebay.co.uk/itm/265105508108?_skw=dt125r&itmmeta=01K3KZJVZXTDXFQSV8F8825AK9&hash=item3db985070c:g:fR0AAOSwPklgYe8r https://www.ebay.co.uk/itm/254920918177?_skw=dt125r&itmmeta=01K3KZJVZXGQ7GA5E0N5ETX8JA&hash=item3b5a7884a1:g:27sAAOSwBTVgYbuc
