Thanks guys, yes the zeeltronic is amazing. I was the one who helped zeeltronic make a cdi for the dt125r 2003 with my specs, data and wiring with the connector blocks pictures. Really helped set the correct powervalve curve and limits with my wr200 top end and using the dt125r stator plate, also the ignition timing.

The 200cc part
Crank cases bored to fit the wr200 crankshaft
Enlarging the transfer ports

The powervalve was damaged so I bought a brand new one at a later date. This is the nickasil bore version and didn't need a re-bore luckily so I bought a new wiseco piston and a brand-new wr200 crankshaft, originally I bought a wiseco yamaha blaster one which did fit in with modifications to the primary drive gear but I wasn't happy with it so I swapped it.

Née crank bearings
Test fit (I later had the crankcases sprayed)

Here's a close up of the wr200s boost ports (before I cleaned them) note: also bought a brand new powervalve afterwards as the dowl holes were sloppy.
Here's it built up (not using the tmx30 anymore)

My custom intake upgrade
Vforce v3 reed block - mikuni tm34ss carburetor
I cut the spigot off the reed block and centralized the flow to match the original and cut bolt holes to match

I cut off the flow guide from the manifold (this is not a restrictor, people think it is but it isn't, removing it will lose performance) I do not need this as my reed block comes with one fitted.

I used a tm34ss from a Aprilia rs250
Note the angle spigots, this makes fitting a lot more easy and the float bowl stays level

I had to carefully enlarge the manifolds bore to 34mm and also increase the size to fit the carburetor in, I managed to add a grip step to match the carburetor (this adds more stability.)
Because the size of the carbs inlet I had to compromise. I tried a yz250 evos rubber boot which almost was perfect but it kept breaking due to age.
So plan B was like this:

It wasn't the nicest way, but it works well

I had to blank off the vacuum pipes on the carb and I also adjusted the autolube because of all my modifications

I forgot to say that my DEP exhaust is for a wr200, so it's perfect for my bike. I had to make custom fixing and rubber mounts. Note how long the silencer was hahaha

Dt125r dep and wr200 dep together. It looks like I'm punching it, can't remember the reason for that
