Anatomy of a Hayabusa exhaust system

[Camel]

Hi Fester, I can't say I'm a magician, probably more of an exorcist, trying to exorcise demons from Hayabusas. Spent most of Saturday trying to find out why Crozzer's Busa was running so unbelievably rich. Found a few things that needed fixing but in the end did a full erase of the ECu and reflashed it with a crisp map. That fixed it.

Kept working on the jig, tapped all the holes and bolted them together, they hold the exhaust firmly in position.



While marking up the front jig I discovered that the crosspipe sits at a slight angle. That necessitated some fiddly adjustments while boring the jig.





It all worked in the end. Just need to fabricate the jigs to hold the end of the catalytic converter in place.
