DT125R FORUM

Merry Christmas everyone!

@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.

@Rob-TDR Welcome to the Forum, that is a beautiful original TDR125R. They seem to be very rare and I prefer them to the TDR125 we received in the UK which looks like a TDM850. Was the TDR250 sold in Italy? If so I think it would be easier to get one of those and keep your Lightburner original as it will be worth more as time passes. The TDR250 is absolutely insane, I owned three of them in the 90s and they gave bikes four times their size a run for their money due to Supermoto agility and acceleration up to 70-80mph as fast as the 750s of the day. Everyone who rode one of mine came back unable to stop laughing, saying these things should be banned etc. Trust me, a TDR250 will always have enough power... Benvenuto nel forum, quella è una bellissima TDR125R originale. Sembrano essere molto rare e le preferisco alla TDR125 che abbiamo ricevuto nel Regno Unito, che sembra una TDM850. La TDR250 veniva venduta in Italia? In tal caso, penso che sarebbe più facile procurarsene una e mantenere la tua Lightburner originale, dato che il suo valore aumenterà col tempo. La TDR250 è assolutamente pazzesca, ne ho possedute tre negli anni '90 e davano del filo da torcere a moto quattro volte più grandi grazie alla loro agilità da supermoto e all'accelerazione fino a 110-130 km/h, veloce quanto le 750 dell'epoca. Tutti quelli che hanno guidato una delle mie sono tornati a casa ridendo a crepapelle, dicendo che queste moto dovrebbero essere vietate, ecc. Credimi, una TDR250 avrà sempre potenza a sufficienza...

@Elan-n Don't worry about it, I've done a lot worse! Sometimes you can be so close to the thing you're trying to fix it's easy to miss something. The main thing is you're moving forward

@kepirok Hi bud, I'd be looking at repairing your original carb or trying to source a replacement, if your cylinder is slightly ported as you say it shouldn't make much difference. Back in the day two-stroke tuners like Stan Stephens etc. used to wring a lot more power out of these engines, very rarely suggested a carb swap unless going fo a full race, rebuild-every-few-hours spec and in a lot of cases even recommended retaining the stock jetting. If your stock carb is really scabby try soaking it in alloy wheel cleaner for 24hrs. The OEM DTR carb also has a slightly angled float bowl which means it's horizontal with the carb installed, a useful feature due to Mikuni designing the TM28SS specifically for quite a narrow range of Yamaha bikes. It can be a bit expensive to get one in good condition but the time and aggro saved (your bike will just work) is well worth it. The biggest problem with the TM28SS is the air screw seizing but this can be prevented by a smear of copper grease on the threads when installing it in the carb body (it's also worth doing this on all the other carb screws which retain the float bowl, carb top etc), and always spraying the entire engine/carb/radiator area with WD40 after washing the bike (get the 5 litre size with free trigger spray from a motor factors). I think your Athena exhaust is the same as the Tecno expansion chamber which I've run on stock carb/jetting with good results. Is your ignition a Zeeltronic? If so they're very helpful and will probably tell you which ignition map works best with the stock carb if you email them.

@Rallyfinnen ciao, grazie per il tuo post. Anch'io vorrei installare il 230 sulla mia TDR125R per avere più potenza. Rimango in attesa di tuoi cortesi aggiornamenti. Grazie

@Calum That site is known even more year's!!!!!
