well, its just passed its MOT, so i guess it deserves a mention on here ..

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.

Semi naked street fighter look, nice - just bolted an L motor into my one. Clutch dragging a bit due to motor sitting for a long time, but goes well.

:D

the look is more due to lazyness than design, I've got a mint condition bellypan, but its a pain to fit/remove lol.

it might be getting an H1 engine shortly, the original one is getting close to 60,000 miles now, it's a bit low on compression and i have a suspicion the head gaskets gone again, runs ok, and doesnt blow coolant, but its consistently forming mayonnaise in the sump and blowing it into the airbox.

looks good mines exactly the same color , hopefully i will be able to sort this exhaust out soon! :D

needs a respray, and a clear screen .. yours has reminded me how tidy they can look..

oh, and its just blown the head gasket again .. but it is on 60,000 miles now..

hi

i have the zx400 and hve found that the cam chain has been fully adjusted. do you know where i can find a replacement . does the zxr engine fit straight in?
cheers
