the famous red spring for the pulley
well... as a warning to other people, it's simple but just not an evening job in a MAX IV.
after removing the engine/wires/cradle then the T-20/shifting rods/chains/adjusters, I got to the pulley.
So If you are planning to change the pulley spring in your Max IV, consider doing full maintenance/dual shifter/t20 oil change/ or other upgrades at the same time as your AATV tub will be empty by the time you get to the pulley.
I'm doing the red spring, the dual shifters and the shimmed clutch spring at the same time, cleaning and greasing while reassembling the beast.
