      @Calum That's nice, how do the KTM pegs fit the DTR? Any modding needed or bolt-on?

        I just ground down the ends of them as they wouldn't sit flush. It's a very minor mod I didn't think twice about it.

          @Calum Ok so they fit easily? I'll think about getting myself a pair of those then!

            Yeah it was simple. I tried looking I could find exactly what I bought. I must have done it after I "finished" my bike and thus didn't document it. But yeah was a really easy mod and now I have Phat footrests.

              @Calum Really nice! My only problem is the budget, those things are like a 100€ 😬 Maybe I should get some Chinesium ones 😅

                    Global pandemic huh? returns to shed

                    Not been doing alot, just wanted to share some bits.

                    alt text

                    After 4 years, finally built a proper DTX Brembo Caliper conversion. Threw some Titanium bolts on for some weight saving, and bling.

                    Custom Bracket and Spacers made, was fun on the old Myford Lathe. Got to force yourself to work in Imperial though...,

                    alt text

                    alt text

                    Plenty of braking power with Ceramic Pads on a 298mm Disc. To manage the DTR Fork, I've rebuilt them with 15W Oil and 35mm Spring Top Hat spacers, this effectively shortens the spring travel and keeps the spring in its stiffest part of the stroke. It works well enough for me at 70kg.

                    Could be better, but you can pedal this thing hard into mid corner so it feels pretty sorted for road use.

                    alt text

                    I've got a USD setup in bits currently, got a set off NOS 1996 YZ250 Forks, if anything, they just look sick.

                    alt text

                    I will do a Build thread on installing USD forks for the DTR, as I think many people want to do it but are not sure about the parts needed to do so.

                    Re-mounted my Ignitech CDI with rubber mounts and polished up my bracket, sadly it seems the company has disappeared. I've never had a problem with my unit and this Programmable CDI is the best thing I ever bought for this project.

                    alt text

                    The spark on this thing is ridiculously good.

                    alt text

                    I couldn't be bothered to fix my ported 3MB 'P' 134cc Cylinder so i went back to my old 14,000 Mile standard bore 3MB
                    Cylinder with a TDR unrestricted Head, and it has been so much fun to ride. Just a torqueey reliable DT engine like I remember it when I was 17.

                    QUICK ENOUGH LOL

                    alt text

                    Been running different carbs for a few years now, and I have to say you couldnt do much better than well Setup Mikuni TM28ss and the 30ss from a WR200 is brilliant for the 125R.., depending on how good you can setup the floats and mixture.

                    This is the problem with any carburettor using the standard Inlet,

                    alt text

                    MIKUNI TM28SS - TM30SS - TM32 - TM34SS - KEIHIN PWK36

                    alt text

                    My favourite so far has been setting up a Mikuni TM34SS from a Aprilia RS250 and Later model RGV250s, (Same engine)

                    Mainly, the Venturi is angled so the Fuel Bowl remains level. But it has a really effective power jet and has been easy to setup, it works really well with just 125cc, this engine barks and pulls great at Mid-Range too. For me, I pretty happy keeping this engine under 140cc. It's plenty fun.

                    alt text

                    I'm using a Modified WR200 Inlet with Boyseen DT200R Reeds. Runs good.

                    I have a 3D printed Airbox to Carb boot I designed, so it's water tight and easier to jet than a Pod Filter.

                    Currently waiting to print a new filament that has the right Shore Hardness to produce a rubber part like the original. You need a good amount of flex to seat the airbox and carb together.

                    alt text

                    This has all been paired with old Nikkon Race exhaust, Handmade, Gas welded steel. There is pretty much no info on these.

                    I bought this from a guy who used it a couple of times and then stored it for 10 years, as far as I know this is the only DT125R Nikkon pipe left in existence. Which is a shame, because this pipe is so much better than the DEP on the road.

                    I'm going to copy this pipe into Stainless steel and just keep it the way it is because it suites my application so well. Very large expansion pipe aswell, the design is unique.

                    Will go further into the restoration of it as it's currently covered in BBQ Black paint.

                    Long term project aye, I've already had my fun.

                      @finchfocker I myself just bought the DCCDIP1 race. Seems like a great unit, just programmed myself a ignition map to start off with, hopefully I'll get a chance to plug her in soon!
