@tbthegr81 change it mate it's not going to do any harm. Obviously allow it to breathe a bit better with a performance exhaust. Next step maybe go up one on the main jet and a performance air filter but not necessary. The 89 model has a restriction in the exhaust in the form of a small washer/collar in the header fixed with 2 spot welds though after all these years and I presume many owners it's probably been removed by now. I highly recommend the dep exhaust. You need to be doing some serious tuning/porting work to justify a bigger carb.
Has anyone ever upgraded the rectifier-regulator on any of the earlier DTR125’s?
From what little I’ve read early 80/90’s unit were pretty shit. Basically anything that runs the lights straight off the flywheel instead of through the battery via solenoids...
Anybody addressed this issue? Know owt about mosfet units, or what is a quality upgrade? I’d really appreciate any input into this mystery 👍 Id love it if my headlight didn’t dim every time I hit the (battery powered!) brakes...
Hello, I am Vito from munich. I rebuild my Dt 125 r from 2001 last winter. I am very happy with the whole bike but i am very unsatisfied with the stock braking power. Is there a possibility to mount a brake caliper that fits P&P? Thank you very much in fellows. Kind regards Vito
Later Re models run nissin rear brake callipers, that’s plug in and play but the brand name is the only difference you’ll see as they’re both single piston callipers that use identical pads.
Also for less effort and cost you could buy a front end of WR125X. 320mm disc, 17” sumo wheels and lots of brembo upgrades
@markus-w cheers mare just wanted to be 100% sure, just cleaned carb today n was full of varnish looking petrol cos bikes been sat ages, jets were blocked too really dirty tbh! Cleaned n refitted but just looped head hose to other head pipe n done same with carb pipes.. I'm in Scotland, cheers mate👍🏼
@calum pulled it out to get a pic ended up pulling legs to see what crack is, dtx stanchions are shorter, the insides are slightly different too ive added a shim/washer ontop of the springs seems to have lifted it abit but still not quite there, not sure how to upload a pic as it says its too big of file
@Baileyboy2008 well like Calum pointed out there’s no such thing as pinning your valve half way if the valve is have way closed you will get zero power above 6k open her all the way and then see what it does
Measure across the pick up sensor. Make sure that you are getting current to trigger the CDI. You will want to follow that pulse from the pickup to the CDI. From the CDI you will see it go to the primary coil. From there it should go to the secondary mutal winding and out to the HT lead. It's as simple as that. Somewhere you are losing that signal.
