@Calum said in SuperDeet125R '01 - Running Project:
@NINJA Sorry, should I have used the "Quote" feature. I was just relaying that @Darty Said it's taken him 4 years and a pandemic to sort his brakes out.
As the saying goes; "Better late than never!!!"

Welcome to every possibly carb option for a DTR, the darty edition.
Never heard of Nikkon before. Pretty pipe I must add proper phat boi. Also good to see you cracking on at last man -
@Darty How do you fit 36mm carb on your dt,what kind of carb boot use for it.
-
@Rizboy We fitted a 38mm keihin carb to a 2001 DTR

Just used a heat gun to up the carb boot and reamed out the inlet manifold to suit.

I am also working on a custom inlet. Very cool inspiration here

Prototype V4, 3D printed in a TPU at 80A Shore Hardness like the original. This is chemical and UV resistant filament and it's rather tough!
This is the final design for use with a pressure mold.
Concessions need to be made for 3D printing rubber unfortunately, so now I'm using M5 Socket cap bolts and the original flange that's molded in the Airbox as a sealing face, it actually works out to be the most effective alternative. Much like a YZ Airbox will use the same design.
The Airbox is so important when jetting a 2stroke road bike, we need to control the flow of air and have a place to store some also! Induction theory carries on. The area inside is free of interruption and the boot helps to increase the velocity upon entering the carb. I'm hoping to gain more torque down low by using that stock Airbox volume.
The design now minimises any angles greater than 55deg, this means material does not have to be supported as we print. As you can see, this is the optimal version as the rest of the print can completed cleanly as a vertical slice.
Job done,
So much more flexibility with jetting. Measure 69 times, draw it once.
Mikuni TM34ss finally finished.
