Z1A restoration

#1 PostAuthor: FreddaAbborre » Sun Feb 26, 2017 10:17 am

For quite some time I have been doing an original restoration of a Z1A, late 1974. I bought it 5 years ago and aware of the time span and the sometimes dead periods for this project I have not posted it here earlier, but I’m getting closer to finish the restoration now so here it is!

When I bought the bike it was in a light chopper mode. Long fork, 16 inch rear wheel. All the good stuffs… But surprisingly a lot of stock parts present, especially original exhaust.

The restoration will be a complete nut and bolt restoration but without going all anal buying only NOS parts. The parts used for the restoration is repro parts, used original parts in very good condition and also restored original parts.

I will list all what’s done and to what standard, and for not finished parts of the restoration I will happily have your expert inputs to finish this project.
I know there are some guys here with a lot of knowledge component wise – what is the correct component for which years and I hope to get some comments along the way.

Some personal background. I’m a mechanical engineer living in the south of Sweden with a long (relatively to my age) history of bikes and zeds. I’m 31 now and bought my first zed when I was 21. It is a Moto-Martin which I still own (in pieces). Other zeds have passed, MKII, Z1000 A1/A2 among others. My history also includes riding enduro.

As the bike looked when I bought it.

Majority of the chassi assembled. I assembled it to get full control of what parts remain to be fixed. Yes it has the wrong handlebars in the pictures…
Have mercy for the messy garage. It has been organized since the picturs was taken.

Haha. Yeah, the local scrapyard cleared its stock so I bought a few..
I bought all zed stuff he had. Which was only a cylinder and cylinder head apart from the carbs.

Next major thing to happen is that I will get engine casings, engine covers and carbs back from water polishing. I'm not sure if water polishing is the correct term or translation, but the surface is treated with high pressurised water with some sort of polish additive. Any how, the parts should look as new I hope.

I will let the cylinder head get new guide sleeves and new threads to one of the exhaust studs. Also have the valve seats machined.

The cylinder it self needs one new sleeve (any one know where I got get one 66mm sleeve?)

I will also need to get pistons and piston rings. There are very cheap sets on ebay. Anyone have a clue if the are rubbish (you get what you pay for) or acctually something pretty good? I mean the manufacturing method has improved since early 70s and the power of a z1 is not high with todays standard.

Or this which is a bit more expansive (and 66,5mm but will ask for 66mm)?

The parts looked even better when I took a closer lock at them.

However the treatment didn't fix the messed up liner...

So anybody with an extra liner lying around, let me know!


And can anybody give me a good advise of a better photo sharing service than photobucket, it is slow, unfriendly to work with and full of enoying pop up ads...

You don't need a photo-sharing site, just "drag & drop" what you want ..... easy-peasy now :smile
