OK, just walked in from playing with the 750.  Got the felt from McMaster on Friday, dang those guys are quick to ship.  I got a sheet of 1/8 and 1/16 and set about making some new seals. 

I measured the OD to be 9/16 and my largest punch is 1/2  so I cut and sharpend a piece of pipe with a 9/16 ID.  Stamped out a ring of 1/8 and 1/16 to test the fit.  I pulled out the retaining ring and droped in the thicker felt but didn't like it.  The 1/8 looks ok.

I had used O-rings on two holes that had nothing in them.  The PO had taken this bike apart to "restore it" and never re-assembled.  Why two of these rings only?  Who the F@#$ knows?  When I pulled the others out they had tiny seals, similar to a fork or tachometer seal.  My 350 Four had felts, so silly me, I assumed and here I am.  It didn't look like the o-rings were wearing or having issue, so I put o-rings throughout.

Wannabe - if you still want a set of these I stamped out a set of 6 that are about 9/16 OD and 7/16 ID PM me. 

If anyone wants a piece of felt I have some of that as well.  However I'm out of the o-ring stamping biz due to lethargy, riding season, VW tuning, bathroom remodel and so on.  The cost of a few postage stamps and envelope won't break me, just let me know which thickness you want.

I would just make my own.
That price is ridiculous!!! It is actually criminal.
Someone is laughing all the way to the bank.

A am sure the material can be sourced.

Ok..I found out you can get this material.
It is a wool felt that is used in electric motors,disk brake dust seals and is heat proof and oil resistant.
The density is what is important. Get the dense material.
Many articles written on the subject.
You can buy it in rolls.

It just has to keep air from leaking into the carb. Matter of fact it is used in air polution filters also.

A teflon seal would work also just measure the shaft and the inside diameter of the carb recess to find the right teflon seal.

No need to make some criminal rich.

Here is a link to material. http://www.tatlee.com.my/catalog/Industrial-wool-felt/Wool-Felt-Sheet-or-Roll-Form/

Also I have teflon paste in a small jar and that can always be applied to this seal. Like I said I would just measure the diameters and get teflon seals.
End of problem.

Here are teflon oil seals:

I have a '78 750k with PDs, and my '74 350 four also has felts.  The o-rings I used are 0.070" thick which is about 1/16.  My concern is 1/8 may be too thick, but according to afastman 1/16 does not play well.  I ordered both 1/8 and 1/16 - we'll see which works.  Shipped ground, should see them middle of next week.

If they leak air then it will never run right. They must be airtight.
