New Billet head?

[Ked0607]

Not sure how different the heads are from Gen 3 and Gen 2 but looks at this....

If you have 6k laying around and are building a fast bike it may be in your interest. The flow numbers are nuts. I can only imagine with the Snails on them.... @SS4Luck @smithabusa @powerfulone

The ones I have had in my hands from those guys were "pretty" but has alot of issues that needed to be resolved before they would be useable.

I saw in a hayabuss group on FB a few dudes said the same thing.

Just overall general issues with it. Seats were not installed properly, didn't use an OEM valve cover (and none was available), alignment dowels were in the wrong place on one and when they moved them, they didn't add additional material so it was VERY thin on one side of the dowels, general cleanup was poor and needed to be deburred, no real means of attaching an exhaust header, cam bearing surface wasn't very clean.

All of the issues could be resolved, but the parts seemed like initial prototype parts rather than something that was purchased for what they were cost. I design and make parts and these would have only been released with an understanding of what they were and that they needed a fair amount of work if I were doing them.

Basically, "for advanced users only" lol.

Am I missing something here? How does a cylinder head work with 4 pistons...? Can't find anything online mentioning an accompanying crank + rods + pistons to mate with this 6 cylinder head. How does this work?

Sorry meant to say "How does a 6 cylinder head work with 4 pistons?"

Where do you see 6 cylinder head at?

My apologies I saw the link to PPR and assumed it was there 6 cylinder head cause i was just looking at it a few days ago prior to stumbling on this thread. I did not know they also offer a billet I4 head for the busa. But anyways, take a look, PPR makes a 6 cylinder head for the hayabusa. Which begs the question: where on earth is the crank, rods, pistons, what is the bore size and other specs? What other mods are needed? I am interested. More interesting in knowing than actually buying, as I can't imagine the entirety of the mod being less than 10k for an i6 busa. But oh man....could you imagine

Take a look at the video of the head on the mill too, looks so beautiful.

Hi. I looked in to the billet head no coolant passages. Still looking in to the CF rods.

Yes, of course. I was talking to him this past weekend at the XDA race.
