B12 and 1100w Akra

[bluedog59]

I'm planning to swapping over from w/c to o/c B12 in my glacial project and would like to use the GSXR1100 Akra. I know I'm going to have do some jiggery-pokery and a sump swap at the minimum. Would the sump off an 1100 Slabbie help ? Has anybody fitted a w/c system on an o/c ?

Why get rid off the 1100 for the dull 1200 bandit lump?

Seems like a backward step?

No ugly water piping etc?

I'm having a bash at making my own frame and using the w/c motor just adds so many things to the "to do" list.

I have a w/c Akrapovic system on a slingshot I'm building. Was a better looking fit than the oil cooled Akrapovic system! Didn't need to change sump. Only mod done was I had to do was turn down the heads slightly on the two bolts for the cross brace of the removable cradle as they just about touched downpipe no.3

@bluedog59 Have you any pics of the Akra system? I find with Akrapovic that a few different versions of designs for the same application.  I own 4 different Akra systems.

In the pic, left gsxr 1100 o/c, middle gsxr 1100 w/c 4-1, and right bandit 1200 4-1.

My 1100 w/c Akra runs 2-1 down each side off the sump then joins into 1 behind the sump.

Different again! This is the version I used. As said they have different variants. Akra might have one type for banana arm and another for braced arm w/c models(?) Either that or there's a choice of 4-1 and 4-2-1 for the same application(?) I liked the way the ones I used were tight to the frame as gappy systems are a pet hate of mine.

The wc system you leant me didn't fit the blandit 12 motor at all as it fouled the engine mounting cradle of my frame so the nature of the frame scaffolding  in front of the engine is probably going to largely determine whether the idea will work or not.

[bluedog59]

The frame is going to have to suffer some mods around that area so I should be ok in that respect. If anybody is interested, there are pics in my thread about half way down page 9 in the w/c section.
