My throttle assembly's return spring no longer moves it back to neutral when it is near 0% or 100%, and lazily returns a little when it's in the middle.  I think I broke it by using a mechanical  throttle clamp 'cruise control' device[1] , I'd been feeling the groaning of the throttle spring when forcing roll-off while clamped, so I don't think the pinion gear of the throttle needs adjusting[2] as the throttle remains smooth and not snatchy.  If I disassemble the throttle, can I tension the return spring to proper, snappy operation?  Can I buy a replacement return spring, rather than an entire assembly[4]?

I would certainly think that you can just replace the throttle return spring.  The spring is very tricky to install.  I had to reinstall mine when I took the throttle clam shell apart to install heated grips.  I used a flat blade screwdriver that I modified with a notch to grab the end of the spring and rotate it around into place.
