ALU Järvenpää aluminitehdas, Alcohol stove

As I got it
Replaced missing pot holders with angle brackets
Heavy oxidation
After a date with steel wool.
Some corrosion in the bottom I hope it holds fuel...

 

Unfortunately it leaks from the bottom, I might try to fix it with aluminium ''solder''

 

Never mind the alci stove, tell us more about the motorcycle engine you're working on! @Kall399

 

T500 Suzuki 1973 Complete engine rebuild. Whole trans was shot due to a design flaw in the engine. ''New'' trans, clutch, bearings, seals, kickstart internals and fix for the original problem cause.
Picture from last autumn when I bought it

 

The stove looks very much like a Koma - like this one.

 

Yes most likely one or both were made with license or just copied from the others design.

Thank you for linking this very interesting

 

Ah the Titan! Fast & thirsty... Looks good for its age!

 

@Kall399
Nice bike. I would say those vintage twins are bullet proof but in this case, it is one with a flaw : (.
A job well done, congrats.

Re Op:
I presume stove is quite small (or very large bolts), if you can tell us the diameter of base, that will be helpful, please? Thank you.
and
i expect you knew but for readers
oy.aluminitehdas a.b.

Thank you.
Never mind my "bullet proof twins"... my bad. Your side cover should have tipped me off instantly.
Yours in an early ludicrous speed 500cc two stroke !!!
Sorry for drift. Granted there are faster modern bikes and I later had some faster larger bikes (probably safer).
Your bike reminds me, my 2 wheel "need for speed" was satisfied in the 70s. Again sorry for drift i remember when kaw came out with their H1 500cc two stroke ("widow maker #1", in '70 was the fastest production bike, a game changer, way faster than anything before it). My buddy wanted me to take his for a ride... that was the 1st bike that WOT was too much for me. I exercised it plenty at 1/2-3/4 throttle, waaayy fast, I got off convinced, that is way to much speed for me. He crashed it soon after.
I later had chance to ride his upgrade, the H2 750 (widow maker #2), i declined flat out w/o regret.
He too decided it was too much and sold it off shortly after buying it.

 

Yeah it's plenty fast 180ish km/h. At least this one was modified with a GT model front forks and disk brake. Just today I got the engine back together. I still dream about a GT750 Suzuki water cooled 3 cylinder 2-stroke

 

The water buffalo! Even thirstier! (and faster... )
