I only use this for bending really long, thick, heavy pipes.
Even so, it’s tough when fabricating the side stand.
A power wrench is a bit pricey, isn’t it?
We got the inspection passed and it turned out great! ♪ Now I’ll do the final tightening.

I cut the SUS304 16φ pipe to about 150 mm…

I’ll prepare a manual pipe bender.
Since it’s mandrel-type, it’s less prone to wrinkling… though not completely wrinkle-free.

What’s great about it is that you can bend even such short lengths.
Plus, no heating required… and you can re-bend if needed in the same direction.
Having this versus not having it makes a huge difference in fabrication efficiency.


I’ll make it by joining two pieces together, so I’ll fit it to the actual part and make it roughly.
Precision? What’s that?




If you look closely, it’s got a bit of a five-pack belly to it. It doesn’t match the Kawasaki OEM water pipe…


I weld pipe A and pipe B in any direction, then combine the round boss and round rod assembly to complete it.
I should have bent the round rod into an L-shape to gain more area (distance)…
But at our shop’s level, it’s side work, so I’ll let it slide (‘ω’)ノ

I was able to simplify the breather routing, which was a layout headache on ZRX models (‘ω’)ノ

The bead roller isn’t working well, so it’s a bit loose… I’ll fix it and spread it out.
I’ve set it up so it can be routed either on the carb side or toward the rear of the frame.
When I took it for a test ride, it was super fast and I was a bit surprised! That completes it.
