Expansion chambers plans / drgs
Evening all.
I’m looking to make my own expansion chambers. I have access to material, a laser cutter and welding equipment.....and I’m up for a challenge.
My question is does anybody have details / plans to enable me to cut the pieces, form and weld?
I guess I’m looking to replicate the lomas pipes (side by side).
It won’t be easy, but I want to take it on as a bit of a project .
Thanks

Re: Expansion chambers plans / drgs
The Yamaha TSI specs are posted on this site. They include pipe specs.
Quite an ambitious project - I wish you success.
Please keep us posted on your progress.

Re: Expansion chambers plans / drgs
Others please chime in - I suspect that those pipe specs would work best if you did the rest of the TSI mods. And from what I can recall the mods result in not the most suitable streetbike?
Others please comment as I have no personal experience with doing the full TSI mods.

Thanks I saw that before.
I guess I was hoping (being lazy) for the “net” shape sizes of all the various cones to get the right lengths and bend angles etc...

I think MK had a good post on pipe building techniques if I could only find it!

Re: Expansion chambers plans / drgs
stock or gp style?
assuming they save a bunch of weight, etc, yeah I'm in.

You could try this guy:
http://www.npowerperformance.com" onclick="window.open(this.href);return false;
He does custom pipes for a living and I guess starting from a batch of one instead of 25.
Currently he's a bit busy but if you have a bit of time, it should be doable.
Edit: Correct form is "has been done"
If anyone knows the BRC 500 project where they offer a 500 cc kit for the KTM300: Neil is doing the pipes for that kit.
