So I tried just removing the side panel, 1 bolt at the top then pull out from the rubber grommets.
I cut the wire tie holding the harness, after lifting it up you have pretty good access to work. I don't see a need to remove the tank.
Just for reference, after you loosen the 7mm jamb nut turn the 10mm nut clockwise to reduce idle speed. When you have it where you like it tighten the 7mm jamb nut. I adjusted it by starting then observing the rpm, then shut it off quick and readjust as needed.
I have it now so when it first starts it goes to 1,500 rpm then rises a bit to ~1,600 then gradually drops back down to warm idle once about 3 bars are showing on the temp guage.
