My busa needz CPR

[Bumblebee]

Thank you for the quick replies, folks. All this from a tank of really lousy, dirty gas.

I love the drawings! I figure that the fuel has already gone thru 2 filters, by the time it leaves the tank and heads to the injectors. This would seem to indicate that the lowest-pass (finest) filters are in the injectors? At this point, I’m thinking that a sticking check valve might explain the slow leak from the fuel tank, when the S-shaped fuel line is disconnected, but not explain why there’s no fuel getting to the cylinders. (The engine does run if I spray throttle-body cleaner into the intakes. However, it quickly dies.) I did the pump tests called out in the service manual, and it’s producing good pressure and flow, so that seems to me to say that the failure to run MUST be in the injectors, as "jwcfbd" and "202mphbusa" suggest. Are those injector filters replaceable? Available? Guess it’s time to study up on the injectors.

I’m not familiar w/ "Schnitz", but evidently I should be.

I apologize for the newbie questions, guys. It was a lot easier when I owned a dealership and had an ace tech who knew all this.

Thanks again for tolerating my inexperience.

More than half the problems people have with motorcycles fit into the last six words in your first sentence.....

.........................................and it takes a lot of effort to get the fuel system all cleaned out and functioning....

As for Schnitz, that is just one place of many who clean injectors, you can also clean them yourself pretty simply... @sixpack577 has done more than a few and can guide you in this direction....

We have lots and lots of experience on this forum as well as a resident retired tech @Kiwi Rider who is a valuable asset.

There are also many, many more who were experts in all things Hayabusa who will be able to chime in to help.

As a result of some additional cramming through the Service Manual, I’ve come away with the impression that the injectors themselves can be removed without messing with the throttle bodies. Is that correct? If (!) all I need to do is take off the air box (I’ll also take off the tank first to have better access — I’m getting danged good at it by now.), and then follow the directions to remove the injectors, I should be able to handle it. The manual calls for new O-rings (which have to be gasoline-tolerant, I assume) and "cushion seals". Anyone know the size of those O-rings and a good source? I’m guessing an auto parts store might stock them. Also, is it important to change out those "cushion seals"?

I’m starting to get a little excited about the possibility of getting this done. ;^) Hope springs eternal, in defiance of Murphy’s Law.

Sure appreciate your patience with me.

UPDATE for any folks following: With @sixpack577 guiding me through the whole process, my ‘Busa is finally running again! The tiny filters in the injectors were shellac-plugged and I rebuilt them. The technical acumen of the folks on this forum is so impressive! Thanks to all who made this possible. I wish @BumbleBee (also my former CB handle, BTW) and sixpack577 lived around here, ‘cuz the beer would surely be on me!
Y’all are great!

Very glad the beastie is alive again.......

Now get us some pictures of you tearing up the streets....
