This one has a square-like headlight (i like) others of this same type have not.. Depends on year of build?

In the UK it was a legal requirement to prove before purchase that you were an ageing hippie, communist sympathiser, sandal wearing bearded smelly wooly jumper clad minimalist with little or no understanding of what a good bike actualy was.

the sound of cz is to die for , the smoke may come frome the exhaust what is full of shit ,or to much oil in gas mixture

[luxfair]

A+ for air pollution. LOL

[kirky250]

when you go out on this do you wear a balaclava and sunglasses?

Sound's nice. Better they smoke than not at all. I use Silkolene comp pre mix 1:40 mix . Ive had no problem's for year's. Great bike.

It has 9.000 km on the clock, has perfect pistons and piston rings and has been added more fuel to conserve. This CZ is conserved and is not in daily use anymore.

thats just normal . had one myself .

not a pc enviromentalist bike but did the job , if it started !!

To much oil, use high quality semi synthetic oil. I use personally Motul 510 1:50 (20 ml oil / 1 l petrol) and there is no problem with smoking :-)

[enfielddnepr]

this much smoke is not normal.. think you need new pistons for this 'rare CZ

[kirky250]

looks like tyres are flat,would make a great boat anchor
