Wrong stroke, too many cylinders, but...
« on: January 20, 2010, 04:49:30 PM »
Any advice about what to look for when viewing a Jawa (two stroke) 350?

No reason...  ;)

It's a bit like buying Russian - you really need to know what you're looking at. There are some nice Jawa CZ's out there but there are a lot more money pits. Unless it's REALLY cheap - Caveat emptor!

They do have some nice sidecars though!

Buy an MZ!!

Chassis parts should be obvious to suss out, but I haven't bought a stroker in years... I'm guessing all the usual applies, listen for rattles and knocks, etc?

I'm no expert, but basically look out for bottom end knocks/ rumbles, little end tinkling, excessive smoking ( yes I know it's a 2 stroke!) could be crank seals going or knackered rings/ bore. Check gears all select and kickstarter works  - Jawa CZ's have a funny combined gearlever/ kickstarter and that the charging system is working properly. They are pretty simple engines but I'm not sure what the spares situation is. I seem to remember pistons are hard to source.  Most East European 2 strokes seem to have problems with spares, even MZ's.

Oh yes the brakes can be 'interesting' if they are not set up just right!

 check gearbox oil- if it's low it can be a sign of worn crankcase seals and bearings (sucks in the oil and burns it).

GC, if you take all this into account you ain't gonna buy it. :D

I used to be heavily involved with the Cossack Owners Club and through them got to know the Jawa Cz and MZ clubs (I've also been a member of the MZRC). To be honest, MZ's aside, I would struggle to recommend any East European 2 stroke unless you have a good tool kit and a lot of spare time. Most owners seemed to spend more time fixing than riding. :(

A good one is something else but in all honesty you would be better off with an MZ - do you have the details of this bike then?

Has it got a sidecar, in which case don't touch it but forward the details to me immediately.

 WHY !!!

You have more than enough Rubshh !.....Errmm Stuff !    ;)

Too Old...cant get the spares as easily OR cheaply as you could !
Having had a few they go supprisingly well,very torquey.
Hope its 12v electrics....where would you get the points from nowadays ?
An outfit I had pulled myself,robG,a slab of beer and camping kit to The Dragon back in '94 at a steady 60.Stopping was a little entertaining.
Capable of crossing a Ploughed field with ease.That was the alloy engined TS350.
And I really liked my CZ 350.Cracking bike.Basicaly CZ 125 rolling chassis with the Iron Barrelled Jawa 350 Motor in it.

Calm down you guys.

My brother is looking to buy it for its sidecar and to sell the bike on to recoup some of the cost. He just wanted to know what to look for when viewing the bike.

At the moment the cost is wrong, but I'll keep you posted. If he passes on it I will post its details here for someone else to have a try.

STOP PRESS - there's been an interesting development, I'll say more if it all comes off... best laid plans and all that...
