CB400SF 95 Engine Case Advice

[Josseh]

Hi Everyone,

Backstory: Noticed an oil leak under my 95 CB400SF and began investigation. After washing the engine off I could see a bunch of JB weld near the sprocket (corner of the case, not the sump). I've took the engine out and found that at some point someones filled it full of JB weld and had a go at mig alu over the top of the JB weld. It's a right mess.

Issue: I can strip the case back and tidy it up (potentially) but at this point I'm looking for a bottom half of the case or full engine, just in case. My engine number begins with NC23E-18 and I cannot find any cases that match. Some posts on the forum suggest there are differences between the NC23E-10, NC23E-13, NC23E-14 etc which are for the CBR400 etc, that makes sense, I just do not know what values exist for the year/model of my bike. Should I be looking specifically for NC23E-18.

If need be I can also show some pictures of the work from some one who thought this monstrosity of JB weld was a good idea.

Any help or guidance would be greatly appreciated.

As far as I can remember, any bottom end from 1992 to 1997 will do the job, only the top ends differ. Earlier bottom ends were the CB1 which had gear driven cams, later engines are the completely different VTEC models.

Thank you for your advice. I'll keep my eyes peeled for a donor engine/case.
