Forks, seals and the the ever quest for another disk

[crashoverrideplik]

So goofing off today in my garage I found a complete Katana 600 front end. It came with a GSXR parts bike I purchased and forgotten about. Anyway after some checking the fork tubes are the exact same size as the B400. Has anyone swapped them before? I was looking at it as a way to get dual disks and a set of forks that don't leak (since mine are leaking). Thoughts?

Yes, this swap has been done on the B4 before with great results.  IIRC, not only are they the same diameter, they are the same length, too, so geometry doesn't change.

Think the 600 shares discs with the jap B4 so as long as the 6 is 190mm between the fork centres then your away.
