Does anyone make/sell weaker carb springs for the Dellortos that would lessen the effort?

There are several different levels of spring stiffness for Dellortos. I have purchased lighter springs from Bevel Heaven, which is my go-to place for carb parts.
I think I got mine from MG Cycle for my 96 Sport. But be warned! Happened to me ONCE. After a couple of miles of wide open riding, 135mph+, when I shut her down the slides didn't drop right away and my speed maintained for a couple of seconds which felt like much more, like 15 seconds. That's why they put those heavy springs in there.
don't forget that carbs with real pumpers (not vhbs) have a slide ramp operated pumper lever. you will feel a real increase in effort when the lever hits the ramp at 1/2 throttle. only way to lessen, remove lever and disable pumper
Oh, and I forgot, if you have bell cranks on your carbs (nothing to do with the pump by the way), swap them out for flat tops. The bell cranks, make like a quick throttle decreasing throttle travel and increasing throttle effort. See Archimedes.Along the same line, we should have a database of throttle barrel diameters. The larger the barrel, the softer (but further) it would turn. I suspect that the 2C throttle is softer than the monopoly piece throttles.
