Radiator overflow bottle

Hello all

Can anybody know if Husky ever put overflow bottles on the late '80s bikes? My 430 auto has one installed and it looks so neat and tidy that I thought it might be a factory fitting. It goes on the front down tube and is held on with a hose clamp.

ive seen quite a few one way or another, and my 88 250xc was a NOS bike...but i have never seen a bottle on one.
for what its worth, i have never had a swede boil on me. i think in order to do so you would have a mechanical issue or be pushing it hard in slow slow terrain. at least for a 2 stroke anyway..thumper is a different story

Both my 430s have bottles

really??? are they wr bikes? or is it a euro thing?

The 430 auto, at least the 1986 one has that bottle. I am pretty sure I have found it in the parts diagrams. Whether any other models in other parts of the world had the bottle I can not say. I am pretty sure the cap in the post 1 picture is different from the two I have.

My bike was brought over from Australia by the first owner and I acquired it in 1990. The bottle was on it then. The black cap on mine has 2 small poppet valves installed - one for each direction of flow. Any excessive overflow just dribbles down a groove cut across the threads.

Both Autos 87 and 86, both imported from the USA!

Autos have bottles because the warm more than 6 speed, but only USA models.

Thanks RUF but I'm not an expert about Autos, only about pole vault, boomerangs and Islay whiskies ! LOL
I've bought a 430 AE 87-88 in France , but without bottle.
No marks on front tube of tied bottle.

this is interesting! so i guess they came on auto bikes, but only some..

Perhaps American ones ?

yes, Michel....only the US version AUTO had that small bottle....
