Lar's just wondering what your plans are for the front fender. As you will get a lot of salt spray even when the salt is very dry. Clean up is another chapter that has been discussed on the site before, it's in the archives. The cleanup of the bike, trailer and support vehicles are critical and can't wait till you get it back to Denmark. You will get a lot of help from others on the site but plan on it in advance.

Lars --

There's also a concern about overheating with salt packed into the fins of the cylinder and cylinder head, especially with the direction they run. 

I had a Model A pit car for year that never overheated until the radiator filled with salt at BV one year.  Just something to think about.

Lar's, awsome build. Very impressive. I do have one thing bothering me though. I don't have a rule book handy but, are those exposed blower drive sprockets gonna pass tech? Since an exposed counter shaft sprocket would not pass, I'm wondering about the blower drives.

Look forward to seeing your bike on the salt

Thanks Glen and Stan for pointing this out.
Initially I hadn't planed on putting one on.
I'd say that maybe on third, to one half, of the bike I saw at last years BUB
didn't have a front-fender....so ?!

Anyway I guess you're right, so I found this fender that used to sit on my BSA cafe-racer



..so I'll adapt that to my front forks.

Lar's, awsome build. Very impressive.
Thanks kindly Larry !...but it really isn't.
Compared to a lot of the stuff I see in this forum,
this is ever so insignificant.

Me too
.-)

Thanks for pointing this out Larry !
I can not seam to find anything in the AMA rule book on the subject.
The Special Construction Class (that I run) -section doesn't mention anything about
belts, chains or chain-guards in general or blower belts in particular
.

The closest I can find is the this, in the Modified Frame Class section:

5.C. Chain/Belt Guard
Minimum length of the belt guard is 1½ times the total span
and a minimum of 1/4" wider than the belt.
Primary cover is mandatory.
Belt/chain cover must extend from center of the primary to the
outer most edge of the rear sprocket.


Even though this is not for a blower belt/guard
I've used that as a guide-line, in that the guard
is (more than) ' 1/4" wider than the belt '.

(...and BTW; I'm doing a chain guard as well.)

Guess now would be a good time to consult Tech. Inspection
to make sure I'm doing this right.



A bit of progress here:

Doing the wiring
and doing the oil-lines by modifying the original lines to my bike
by cutting and soldering and bending etc.,
and experimenting with a different seat




Thanks all for your interest and for helping me out !!!

Lars

I would most certainly run a front fender to keep the salt spray down for you and the bike........................Check with Drew regarding belt/chain/pulley covers ......it's a long way to come, to get turned down in Tech. for a no run.

It certainly is.
Checked with the ever helpful Drew;
my set-up is just fine.


One great thing about doing stuff one has never done before
is that one gets to buy tools one has never had before,
like tube-bending tools



Note that 'trumpet'-shaped spring thingy.(Hard to see on the pic, but it's a wound spring)
I'm sure this is old news to you but I've never seen such a thing before.
Goes around the tube and you can hand-bend it without 'kinking it.



It actually works surprising well.

I bought the tools for making the oil-lines.
This is the initial set-up.
The clear hose (with a bit of heat-protection on) is so that I can check the flow
for the test running.
Will change that later




Did the clutch (yep: foot operated) -release arm
Not the most elegant solution, but it works




I'm behind schedule but catching up.
Expected start up early coming week.
Then 10 days to work out bugs and finish a dozen small things.
Then dyno-test.
Then two weeks tuning the engine and dyno-testing again.


Once in a while I sit on it and go
BROOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMMMMMMMMMMMMMMMMMM

Hey Lars
It's really a great build
I was just at a friends place, he works for a gut called Jim Parker, in Australia who does Indian resto's.
I hope with all your new bending gear you are not planning to use copper lines as they can split with vibration.

Fabulous machine. I'm in envy of your skills!

 Just a couple of things I can't help notice about the exhaust that might save some grief once on the salt. The rules for BUB, in section 2.B exhaust, state that "Exhaust must be directed away from the racing surface, rider, and rear tire". It looks like your pipes point generally down toward the ground in the pictures. If they really are it will probably be a "fix it before you can run" gig in tech. Which might be a real problem once you are there.  :|

Also, just a personal thing with me but something you might want to think about is the sever slash cut at the end of the pipes. It looks cool, but if you were to go down and tangle with one of them it could turn into a big hypodermic needle and easily punch through some part of your body that you really would prefer to keep unmodified. :-o
Ah, this is obviously some strange usage of the word 'safe' that I wasn't previously aware of.  Douglas Adams

Class letters/numbers need to be readable by the starter, mostly, while vehicle numbers need to be visible to the folks in the timing tower.  Think of it that way.  Bigger is fine, and for sure -- make them of a color that contrasts well with the bodywork of the car, and also think about not having them the same color as the background (the Salt) for even easier reading at a distance/at speed.

THE timing trailer at the salt is 800 to 1000 ft from the courses and we can't read any numbers. The starters tell us whats running on each course. I don't know what the distance for USFRA or Bub have but it's a safety issue if yoy are close enough to read the numbers.
