hi-temp black covered...
warp and weld-breakthrough issues were garanteed with my low skills.
i knew i'd been ashamed of the results .
i could've done better if i'd done:
-4mm thick plate, same design,
-custom washers tack welded in the same positions,
-4.5mm holes to be simply tapped M5.


BUT..
the real point here was going light-weight, rather than being cool and good looking.
it weight almost the same than the plastic one, ugly but it doesn't overload the hoses supporting the carbs from the manifold.
(the 4mm thick plate would've weight a lot more. checked with cad)
