Ah, okay. I think I'm running into the same trouble that you experienced
with the large ID clamps. On my Quota, it uses a two piece spacer with
one edge (the part that comes into contact with the clamp) rolled so as
to provide a larger seating surface. I think I'll give a dealer a call
to see what the availability is on those.

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!

Hi Greg,
I used the stock bits the same as Joe. The spacers I used was the
one-piece type - like a short section of pipe with a cut in it.

Hi Joe,

Thanks for the information. One question for clarification: For the
pieces that fit between the header pipe flange and the collar that gets
bolted to the head, were they of the two piece split collar type?

Greg,
All I did was grind off the short spigot on the Loop header so
the flange was flat, then used the standard parts for the T/T3 pipes
that fit between the flange (on the header) and the exhaust collar (that





gets bolted to the head). OEM parts.

I'm going to be mounting a set of T3 heads on my Ambo...but still use
the loop header pipes with just the end chopped off. I know others on
this list have done this. What size pipe did you find/use to fit the
diameter of the header pipe properly?
