LOL...seams I could make good money selling t-shirts at Speed Week.

Wish I could go there.

Octane 98,
     Nice choice for breathers, What style fire sleeve are you running on your gas lines in your BUB class?
   Rocky
   1957S/VG

Rocky;thanks for pointing out there might be a problem
with the original breathers. You were right.

As for fuel-line sleeving, I'm using this stuff:




"..TEMPROTECT SLEEVING

Braided high bulk glass-fibre sleeve, silicone coated. Coated with iron oxide silicone rubber
 which will even shed molten steel , aluminium and glass offering outstanding protection
 to hoses, tubes and cables in a variety of hostile environments.
Continuous operating temp. 500F (250C)
Max. short term exposure 3000F (1650C)
Flame resistance - Very good
Abrasion resistance - Very good
Flexibility - Outstanding
..."
Water & Oil resistance - Outstanding.

Octane,
  It looks like a good choice to me. I am using a similar product from 3M over here but I am applying a kevlar sleeve over it as well, to prevent any exploding engine fragments to cut thru?.
  Your'e welcome for the breather lookover, beleive me if I see spomething I am going to let you know so when you get here, so our  others will have an easier time of getting you down the course and in the pits.

Lars,
I was looking at your intake manifold/plenum and was wondering how it seal into the inlet ports. I re-read your posts and it looks like the 'spigots" on the sides of the manifold are inserted into the barrel inlet ports when you assemble the engine. How does this seal? Is there some level of "give" to allow for heat expansion and vibrations?

I am not a big  bike "guy" but there are so many really neat bikes being built for the BUB, and ours is one of the neatest!, that I am going to plan a "business trip" to Salt Lake City the week of the BUB and probaby just happen to stop by. See you then.

I hope so
.-)

Yes; the 'spigots' are inserted into the intake ports/'necks'.
The seal I mentioned earlier ( page 4 I think) :
..............................
Here's another small improvement on this almost-seventy-year old engine.
Originally the notorious 'sealing'-rings between the cylinders and the in-take
is made of brass, which inevitably will  turn brittle and leak.
Don't really want that, particularly on a blown engine.

Indian Parts Europe has managed to have these
space-age-unobtainium thingies made:



..from some sort of nylon-like material that will not change properties
subjected to intense heat (and cooling and etc.).
You get them oversized and they are then machined down
to your specific (in this case ; home-made) intake,
for perfect fit.
...............

As you can see it's  tapered  ( is that the correct term?)
and there's an 'opposite' 'taper' inside the bolt-thingies
that screws onto the outside thread on the intake-'neck'



Other people's experience with these intake-seal is that they really do
keep tight, even on my friends souped-up Chief.

This bike running alcohol should experience
less heat expansion etc., so I'm optimistic.

The part of the intake with the 'spigots'
will vibrate along with the engine,
and then there's a rubber-tube connection to
the second part of the intake which is mounted to the blower (bolted directly to the frame)

If the seals don't seal, this being blown and all, I'll take it from there.
I'd rather not, but may be forced to, use some silicone material

Thank you for your kind words.
Yes; please stop by and say hello!
See you.

Seams like it would work like a big compression fitting.

Do you think the alky will mess with your inserts?

Thanks Willie !

We'll see;  Testing seal, submerged in methanol




BTW: the sealing-"cones" are made of (click:) PEEK / Polyaryletheretherketone

No sealing cones were harmed in this experiment.
PHEW!



Been kind'a busy today:

Finally picked up the tooth-belt / wheels:



Ratio is ..erh...semi-educated guesswork: 48:26
5000 engine rpm --> 9230 rpm at blower. (10000 is apparently the max. for the blower)

Filed down some of the head and cylinder-'fins'
to make it possible to remove / reinstall the silly-shaped intake
without having to actually remove one cylinder



It's now doable (just) moving it to the right and then up and away.






We made the intake 'inserts'



..that goes inside the two intake-halves.





...to be connected with a silicone/rubber hose.


Trail-fit of wheels/belt:




Ha ha ...that machine look wiiiiild !
Goodness, I love it!

Thanks guys !

Yeah Rocky; I test all things that I plan on using (or maybe will use)
to see how it stands up to methanol by submerging them for a couple of days:


ARALDIT two-pack epoxy glue it turns to a soft-ice like substance.
Two-pack metal-filler disintegrates slowly.
Silicone like PERMATEX and CASCO seams to be totally unaffected



The 'raw' tooth-belt wheels/discs Kenneth milled to suit the drive (and blower)




..so we made a "final" test-assembly



...to check if things lined up.

Then pulled the whole thing apart to do the last welding on the frame
and today I'll take it to the sandblaster.

Funny; folks ask me how's going with the bike
and I tell'em we're pretty close;
then they look at the present state (as of yesterday. Kenneth showing the frame):





...and they think I'm nuts.

Mmm; maybe so.
