its taken ages to get it to where it is as Emma uses it everyday for work, so it tends to have bits thrown at it overnight rather than spend a week in the garage getting it all done properly ..
basically its a 1988 ZX4 (ZX400-G) which looks like a mini-ZX-10 (the eighties one) but has a ZXR400-H1 engine, and a very similar frame (subframe isn't removable though) ..
mods so far..
ZXR400-H1 forks
ZXR400-H2 swingarm
ZXR400-H2 wheels
ZXR400-H calipers
floating front discs
goodridge braided hoses
L model mph speedo and matching rev counter
stainless pattern headers (copy of L model zxr)
stock L model end-can
ZXR400-H1 carbs (32mm, original ZX4 is ~30mm)
ZX-4 needles (to match ZX-4 airbox, which is like an H but bigger)
#98 main jets
it did have a micron system on it, but was a bit loud for a commuter bike, and i've nicked it for another bike now :)
also just had,
front wheel bearings
rear wheel bearings
head bearings
swingarm bearings
chain
sprockets
HH pads
replacement fairing/headlight/screen/indicators
it goes, stops, and handles like a zxr.. but has a comfy seat, lower pegs, a fuel gauge, hazard lights (!) and a screen that actually keeps the wind off you at 100mph +
now it just needs some paint to tie the replacement front fairing in with the rest of it.
