Santa Cruz Rider, welcome to the wonderful world of VMax-dom. I suggest you change the brake & clutch fluids immediately, unless they are clear "like water." The flush will help to remove moisture which can corrode your parts, and also any particulate matter which will become sludge in the system and can eventually plug-solid a line, which could lock-on your brakes, or make it impossible to work the clutch.
Changing the front fork fluid should also be a maintenance thing. It's not uncommon for a bike to have leaky fork seals, oil film on the lower part of the fork(s), the slider. Replace the seals before changing the oil if you need replacement. Changing fluid on a leaking fork seal is a waste of time. The hardest part is to break-free the hex screw to disassemble the downtube from the slider tube, the screw is accessed thru a hole in the bottom of the slider after removing the front axle. It's a hex allen wrench fitting, and an air tool is best to loosen it. Do NOT remove the fork cap before disassembly! You need the fork cap to hold pressure on the damper rod that the allen screw inserts-into.
Your brake pads probably don't yet need replacement, but going to front HH-rated pads will increase your braking abilities, and is probably one of the cheapest things you can do. Check for the groove down the center of the pads, if you don't see a groove, or it's very shallow, barely there, time for replacement.
Since the Bay Area weather can be cold and wet, w/the fog, I think you would probably be happier w/the larger windscreen. Be aware that it does affect handling at highly-illegal speeds, if you are 'hell-on-wheels,' get the smaller flyscreen 1st. It won't be very expensive, used. New they're about $140 (GIVI) but the OEM Yamaha part is probably obsolete from the dealer, though they're a frequent item on here or ebay. I'd take a look at davesax36's offer.
