This is my build project started with a ZX4 idea was to rebuild it but parts are a few and far between
, was going to fit the H front end also rear end, long story short ended up getting front end, rear end and frame with sub frame so basically turned into a H build with ZX4 engine 
. Frame, sub frame, wheels all powder coated, frame is satin black. All bearings replaced, engine recon from head gasket up. Various parts polished by myself. 636 rear shock fitted also has the 400 spring fitted so it doesn't rub the swing arm. All work done by myself, it's taking shape nicely i think, all comments welcome.Thanks for looking,
Andy
what year 636 is the shock from? I have a 2007 zx6 shock in mine with a custom made spring but I've managed to chip most of the paint off it! Keep the pics coming! I'll get my 400/636 project outside in the daylight tomorrow for some more pics. 
to fit the ride height adjuster same on bottom fitting. As for the spring it has been powder coated, fitting was not a problem I used ratchet straps on each side to compress removed bottom spring retainer, stand well back and release straps. The 636 spring is shorter and wider and rubbed on the swing arm so fitted the 400 spring a bit longer but right width. specs say 12-24mm preload if i remember correctly which is within the limits with adjuster rings near the top of the shock. also has the benefits of three way adjustment without it being rock hard and shouldn't bounce me out of the seat with the amount of potholes about.
