I'm in the process of knocking up a few shortened sumps for the CBR900 engine (919, though I think the 893 is the same?)

I may have 2 spare to sell once I have built my spare engines up.

Whats included...

standard sump shortened by ~15mm
sump plug relocated to the side of the sump to give even more clearance
shortened oil pick up

all that is required for it to work fine, is you need to take a narrow file and castellate the end of the oil return as the clearance is very tight, if you dont, the sump sits flush against it and your oil filter will blow off....
so the end of it looks kind of like this, http://www.reactiveparts.com/ekmps/shops/reactive/images/kawasaki-zx10-r-castellated-front-brake-caliper-pistons-41900-p.jpg

If I can get hold of a few returns I can include these in the package
mines castellated (just filed one way and then 90degrees to it) and works fine now

I'll also be looking into adding some simple baffles when I get back home to help keep the oil where it should be

If any one is interested in one, let me know
I could also take your standard sump and send you a modified one in return

Here is a photo of the first one I completed to give you an idea

893 - 919 are all the same.
