Having had 32/36 , single 45 dcoe, quad mikuini bike carbs , 38mm dual L series huitachi sus, 44mm dual 240z hitachi sus , and now hs6 genuine sus, the british are easiest to set up and for spare parts.
The quads were most responsive and powerful(pain to set up and tune) and i wouldnt bother single dcoe.
The 32/36 is easy and almost as good for sus.easy to set up and buy.
Sus give about 90% of the total seat of the pants power amd response of the quads but easiet to work on imho.
So my scores out of 100% for performance
Stock 50%
32/36 70%
DCOE 80%
38MM hitachi SUS 75 %
44mm hitachit sus 85%
Hs6 genuine sus 90%
Quad mikunis 95%
I am reserving 100% for efi
