Yes, these are the stock size. The TR6 came with 1.75 ZS carbs. Thus
the HD6 is 1 and 6/8 inches, which is 1.75, same as the ZS.

I not sure why Don would recommend the HD8s. They are bigger and will
pass more fuel, but a stock TR6 setup can't breath well enough to take
advantage of this IMHO. With the HD8s, you'd need to open up the
manifold, port it, and add some lift to the cam to really see the
benifit.
The switch over to SU's on a TR6 is to go with the HD6's. Paul
Gilders did this on his six, and he says that it runs much better than
with the Strombergs.
Good Luck with it!
