I have no knowledge of the 400 frames, but if you're going to go to the trouble of a monoshock set up, you might as well go with a newer aluminum swingarm. One possible stumbling block will be whether or not you need an offset sprocket, and if anyone makes on for the 400...

the fram is pretty much the same as the 500/550 i belive or one of the bigger models

What's the inside frame width at Tue swingarm pivot? Kz900-1000 frames are about 9.5" wide......

2 secs and i will go measure now. lol. also teh wheel space aswell

224mm at the pivot end, and 237mm at the wheel end

So that's approx 19mm narrower than the liter Kz. If you don't get any other responses here, cruise/search the projects section for swingarm widths on various builds. I can tell you a Triumph Speed Triple single sided swingarm is 285mm wide. Most guys here use swingarms that don't require frame widening. Perhaps the 650s have a narrower frame than the 900/1000s, and lots of guys mod them....Perhaps start looking there

i have managed to get a GPZ550 swingarm, the unitrak one for £25 needs a good clean and refurb but im sure it can be altered to how i want it. hehe. will pay for that friday when i get paid. lol. then its just a monoshock needed..
