It's 125 lb. Not light at all. See

have a look on the luciole site that phillip vesaire posted and note
the slight difference between the stock engine and all its
accessories, and the engine as mounted in flying condition. I wouldnt
have believed 50 lb difference but it seems to be.

Yeah, something changed while I wasn't paying attention.

Up through 28 or 29 horsepower was in that lower range of weights, IIRC.
However, everything above 23 hp appears to now be part of their "big block"
series, which is around 125 pounds for the air cooled version. There is
also a liqued cooled version, which is even heavier.

While the "rest of the story" is probably interesting, your point is well
taken.

BTW, the 23 hp Briggs engine (like the 20 hp Kohler engine) is still in the
weight range that we remembered--although there does not appear to be any
advantage in horsepower per pound.

My 38 peak hp Generac, stripped for flying and direct drive, weighs
about 79 pounds dry. It stays plenty cool installed as a free-air
cooled pusher on my Thunder Gull. Valley Engineering is working on a
version that they think will be about 70 pounds.

That's more like it. How much do they think they'll sell these
things for once they're ready?

OK, so far so good.

I did a quick web search and found a model GHT990, which is a 992cc V-Twin
that seems to fit the description; with a max power of 38 hp and a
recommended power of 32 hp. It is stated to weigh 119 pounds as delivered,
which is about six pounds lighter than the 33 hp Briggs--for which I did not
happen to notice graphs for peak and normal power--although they almost
certainly exist.

The question is: What did you have to remove to reduce the weight by 40
pounds?

I like it, I think, but is there an English version available?

Was the link at the top above, a BMW conversion?

HKS would not be at the top of my list.
