FPP Mod chamber or limited chamber stock???

[Grant]

My octane was "stock" when I bought it according to owner. Every octane I have see has a mod chamber factory pipe. They have all been 02 or 03 boats. Did 04 have a different chamber?

I had a B pipe on a 650 that I thought was a 701 chamber but turned out to be a FX-1 chamber. So I understand factory pipe made a variety of b pipes. Is the 04 octane chamber specifically for the octane or is it just a Yamaha 701 chamber?

Did most people / racers upgrade to mod chambers so that is why I only see them on octanes now?

I have an '03 octane I bought new. When selling the pipe called factory pipe and asked what it came with. They said it came with the mod chamber. I'm pretty sure it is just a yamaha 701 pipe and chamber.

It's definitely a SuperJet Mod pipe, with the added bonus of an oversized outlet sleeve on the end, over the stinger... which makes it fit the Octane (and RN SuperJet) hoses better than a regular SJ mod pipe does and it diverts the stinger water out around the exiting exhaust. I believe its the same as the Wammer SJ mod pipe, sold only by Wamiltons.

Huh, that is kinda is disappointing to hear. :confused:
Now I have to try to figure out why I have a limited chamber.

thanks

How do you know it's a ltd.? The newer mod doesn't have a weld around it like the older ones. How long is your chamber?

I was speculating simply on the lack of the forward weld. I will check the length someday. thanks for the info
