DT125R FORUM

@Calum thanks buddy got it booked back in this Wednesday leaking bit of oil new seal seems not to powerful as it should be would a full engine rebuild be beneficial to it or does it just need a tune up

@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

You’ll need a full electrical circuit and a battery to run YVPS as its intended but I’m sure there will be a workaround

Less is more then cheers guys. It’s the reason I used hylomar red before, it’s easy to apply thin and evenly… I’ll get out the black mechanic gloves and dab on some RTV…

Yeah, a closed void would be subject to repeated heating and cooling stress. It’s also really handy for helping get the cases split I remember that I crapped myself when I first found it. I covered it with sealant

Oh interesting. Seems like its a collaboration with Italkit. No good for a road going machine. You won't be able to run any lights etc. I'd recommend grabbing a lithium battery to go alongside this. I don't think the ignition timing is reprogrammable and it has a fixed static angle. So it terms of flexibility, from the limited information I read, it seems very limited. Great for race applications where you are basically open or closed throttle, but I'd steer clear for road use. Ignitech or Zeeltronic ignition systems for the win for a road going setup.

Yeah, I've always had my eye on an Lanza 230. Once upon a time you could pick them up dirty cheap! But the price of them now, I can't justify it and I just think there are other bikes I'd rather own. Sticking with the Yamaha family, I'm now fully invested into RD350s. I've sort of always been around Aprilia in some shape or form, but I think if I'd to get another supermotor or trail bike, it'll be an EXC300 TPI. That's if the electric bikes don't suddenly take off

Typically what are you gaining on a two stroke with engine braking... It's not like a four stroke. When down shifting I always blip the throttle, to both rev match and maybe give it a squirt of oil. I certainly wouldn't be going down a big hill engine braking the whole way at high rpm on a two stroke. Nice blips on the throttle and a high gear to keep the RPMs down. When it comes to competition bikes, well reliability is all out the question and if engine braking does even a fraction of slowing down then it's worth it, but for road going use I only engine brake in an emergency.

Just had a heads up from Borut this morning he did apologise for not letting me know on recent emails that there is probably a 6 week waiting list from order date

@Michaelashbrook As others have said it doesn’t make any difference which hose goes where, and they’re not really needed in a country like the UK with mild winters. However they also serve another purpose which is to make the cooling system self-bleeding when refilling as the one on the thermostat housing comes out above the actual thermostat, so all you have to do is fill the radiator slowly and you end up with no trapped air (this is why bikes like the 350LC and a lot of MX bikes have bleed bolts on the head and barrel etc.). So it’s useful to just run a single hose from one banjo straight to the other and bypass the carb; you still retain the self-bleeding cooling system but it’s a lot easier to get the carb off for cleaning, jetting and float height changes etc.

@Michaelashbrook Doesn’t matter which side they go, as long as they run through. Is that what you were asking?…

@HOTSHOT III Yes bud I keep checking I’m really hoping that they don’t let me down the bikes all rebuilt and looking gorgeous just waiting on the zeeltronic had the choice to refurbish the original one when it got tested probably should of took the cheaper option lol

Is the early model tzr exhaust shorter than the others. I ve seen a giannelli on ebay for early models Not sure if it's my eyes but it looks slightly different
