Hi Greg,
The i.d. of the spacer will be a little smaller once it's in the head.
On mine the spacer contacts enough of the o.d. of the headpipe flange to
do the job, but just barely. Kind of fiddly to get the headpipe
centered, spacer in correct position and nuts tightened all at the same
time. That's why I had the special headpipes made for Sophia with the
T-style flanges and Loop curve to them. If I ever get them back from
EPCO, I'll put them on! :-)
I tried getting some .125" thick x 2.5" diam. steel washers at Lowes and
then machining them to fit over the headpipe and into the head. Would
have given the spacer much more to press against than the rounded edge
of the headpipe flange. But ran out of time to shorten the spacers for
use with the washers and still get the flanges in place.
If I remember correctly, the finned securing flanges that hold
everything into the head come in two varieties. One has a smaller i.d.
and came on the milder tuned engines (Convert, G5) the other on more
sporting models (LeMans). Headpipe diameters were different? Ran into
the same thing with the billet aluminum flanges from Guzzitech that I
originally planned to use. Would have had to whittle out some new
spacers to use them and just ran out of time. Maybe I'll use them in the
Sophia version 1.1 mods I have planned for this winter...

Hi Charlie, I've got a pair of those spacers, but it doesn't make sense to me...the inner diameter spacer fits over the outside of the flange on my header pipe and inside the flange that secures the header pipe to the head. I think I'm missing something here! Charlie Mullendore wrote:
