Hello, everyone, I am the recent owner of a Kawasaki Z400 1981, +18000miles, and I am looking to customize it into a cafe racer.
I will try to post the progresses on this forum every Sundays.

It is my first build, I am not experienced but I will surely learn on the way. I will next Sunday send some renders of what I would like it to look like.

While I am waiting for the bike, I am doing some research for different parts, perhaps you guys can help me with that?

For starting I will begin to remove any plastics and will map the electrics in order to ease the wiring towards the end of the build. I will than will cut the sub-frame, and install and modified if necessary the new swingarm.

What are the easiest swaps for a swingarm, fork and tank?
For the swingarm I have read that an 2010 Kawasaki Ninja EX250 could be a direct fit, however mounting will need to be added for the side shocks.

As anyone have good literatures about the detail specifications about the that particulate bike?

Thank you in advance for the help!!!

Hi and welcome. I dont know anything about your bike or potential donor parts but good luck. Theres plenty on here who will. Where in the uk are you? Im just by brands hatch.

Hi, I am located In Leicester, I am currently working on the carburettor, which look extremely clean, however the diaphragms need changing as they are puncture, Therefore I am looking to get some, They cost up to 70 GBP for the pair. I did some research and they are K-71 diaphragms for a Keihin CV32 carb, which can be found on several model in the Kz/z serie. I still need to look for the dimension as perhaps I can find another cheaper alternative from another bike, which might as well fit.
Cheers

Sure NRP will have what you need at a reasonable price

That s amazing, thank you for that, I ll contact them to see if they have a pair for the G3,
btw what does fitted and loose mean in this context?

Dont know tbh, all my z bikes run vm carbs. Ask nrp when you talk to them and let us know. I always use allens performance for carb bits but i know nrp to be ok also.

Fitted means you can send your slides to them for fitting they just push into the plastic bit on the slide. But if you rip it getting it on it can get expensive.
