Spend a few hours at Moen's place ( Indian Parts Europe ) the other day
talking about ideas for future modifications to the bike.
One thing came up:
the possibility to beef up the engine by installing a crank/con-rod assembly
of somewhat stronger build.
From the left,
rods from: HD WLC , Indian 101 ( more or less like mine ) and HD Sportster.

That Sportster thing certainly looks the part.
It's not too difficult to cram into da' Indian case.
In fact it's a rather common thing to do and he has (click:)
all the parts required.
The thing is that it will 'stroke' the engine which is not a bad thing
and if I wants to keep it in the cc-class , I can revert to original size 500cc cylinders.
Mmmmm: worth a thought.
Talked about carburation and some interesting things came down from the shelves:
A bunch of , to me, rather odd carbs, the GARDNERS:

Look how the slide moves
downward , the needle is static
and the fuel move up through the slide ...huh !?

Weird, but I've seen a Vincent streamliner from the UK with these on.
They do work really well.
Then this funky old S&S alcohol carb

One type that fascinated was these

The Wal Philips injectors.
A fuel-valve at the top and a butterfly inside.
Adjust the mixture by changing the relative position of the two.
That's
it and that's
that.
Absolutely brilliant.
He's got some seriously mouthwatering stuff out there.
Have a look:

Weslake, Jawa, JAP, Ariel and Triumph racing engines.
On the top-shelve you can see part of his collection of magnetos.
Apparently the best ever are the ones from some Vincent engined
'drone' airplanes the Brits used to practice shoot at or something.
Nice stuff indeed.
Have a great weekend ya'all !
