I just knocked out flanges for 10 XS400 single carb intake manifolds. Material is ordered to finish the manifolds next week... TIG time!!!
All 6061 T6 aluminum, CNC flanges, TIG welded, with optional vacuum tap and either straight back or out the side carb location.
Manifolds will be finished to order from the runners to carb due to these options.
Here's pics of the flanges being machined (6 pieces on the fixture), and a finished straight back manifold with vacuum tap.
Of note, due to XS400's crank phasing, one cylinder always runs leaner than the other. Keep this in mid when tuning your single carb setup no matter where you got it.
I would run one side too rich and compensate with spark plug heat range. Safer for your motor's lifespan...lol
