Thank you for your kind words. This thread was my first thread on TBHP and also my first ownership thread. Now, in the past 11 years I have active threads for all my vehicles that I currently own and document their journey on regular basis.

If you liked reading this thread you can also read the other two stroke thread of my RX 135, RD 250 Daytona Special and RZ 350

Re: My Barn Finds: Yamaha RD 125 & RD 200

Mini Update

The restoration on both the RD 200 and RD 125 are progressing ahead at a good pace. On the RD 200 the powder coated parts have arrived and the painting process for the other parts should be completed in a few days. Ideally the painting should have been completed by this week but the painter was not available for a few days and the tank needed extra attention as there was a lot of bubbling and needed tinkering work. Post that after epoxy sanding, there's a round of bodyfiller again followed by sanding and then sprayed with 2k primer for the final paint coat to be applied.

On the RD 125, the chassis was sent for sandblasting post the welding work followed by powder coating and all those parts along with the engine casing and blacks are ready. Further, the boring of the piston and blocks have been completed along with the crank rebuild. Now, once the shaper work on the blocks are completed the engine will be assembled and then work on the magnet and coil plate can be started.. So the RD 125 still has loads of work left…

Some pictures…

The RD 200 tank scrapped down to the bare metal

Finalising the paint shade. The one on the left matches the shade of the OE oil tank that i git recently. Went with the lighter shade on the right

The RD 125 crank is now ready

The smallest twin crank you will come across

Luckily was not as difficult as the RZ crank to rebuild

Boring is complete as well and only the edges need shaper work. It was a challenge to get a machine to fit such small blocks

The last two do look a little alarming But I guess they are part of the mudguard and not the tank. Lots of labour of love going in, I hope we see another steed shining in its new armour(of paint) Coming soon.
