Rick, I have a question on the late H1 exhaust systems (73-76).
I noticed each year is slightly different.
H1d - has front mounting tabs, solid rear mounts, center pipe has extra
rear tab that bolts to the right pipe. Front mounting flanges are smooth
& have the small holes. No stamped markings.
H1e - front mounts eliminated, rear mounts have rubber inserts. Flanges
have large holes & have a rough finish. Stamped "KHI 500 H1"
H1f - stamped "KHI 500 H1 DGM 13127S" (this same number appers on the
air cleaner & snorkle)
KH500 - stamped "76 KHI 500 H1" has an inside coating to reduce noise.
Then there are 74-76 style pipes with no stamped markings. I assume they are replacement pipes.
Is this info correct ?

That's about the score on it Ed, you will also notice that most of the
H1d pipes have a thinner flange where they enter the cylinder - - But I
just checked 2 NOS H1d Right pipes and one has a mainstand buffer locator
and the other doesn't.
