The 200cc part
Crank cases bored to fit the wr200 crankshaft
Enlarging the transfer ports
Bought this off Gumtree, all threads stripped, I had to use a m10 helicoil kit on the head studs. 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.

A few comparison pics
The new piston
Powdercoated in my favorite colours
-
Old vs new haha
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.
-
See what I mean?
-
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 also removed the top of the airbox previous to this mod
-
A few pictures of it fitted.
-
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
-
The silencer was a bit long
So I cut it down, I'm after a different end cap if anyone has one spare?
