You probably already know this...
--Change all fluids: brakes, engine oil, fork oil, rear shaft drive gear oil, engine coolant, etc.
--Check the condition of the chain/belt, if applicable, and change out if any doubts about life left in them.
--Check the electrolyte level on your bike's battery (flooded); check its age, replace it if it is more than 2 years old (flooded), or if more than 6 years old (AGM); see below about a voltmeter/battery monitor...
--Install a voltmeter/battery monitor on your bike prior to the trip to monitor the electrical system's health on the trip: if the reading is below 13 Volts when running above 2,000 RPM, you have a problem -- get it fixed ASAP; if your battery reads below 12.4 Volts (flooded)/12.6 Volts (AGM) in the morning, before you hit the starter, check the charging system, and if that is working, your battery is dying...
--Check your electrical loads to see if you are near the alternator's limit: add up the max, current draw for all accessories (heated gear, especially!), then add in the amperage the bike requires to operate down the road; subtract this from the max. current output of the alternator, and make certain you have a positive number greater than 5 Amps, or your bike will leave you sit somewhere...
--Check your maintenance records for any replacements/adjustments which are anywhere close: filters, valve adjustments, etc.
--Check tire tread life, and condition -- replace if you think you may not have 4,000 miles left in them (give yourself a margin for error).
--Pack up your bike with all of your gear, and take it out on a test drive to check for balance, and handling with it fully loaded, in rain, if possible.
--Check the age and condition of your gear: riding suit/jacket/pants/boots/gloves; check the condition of your rain gear (if applicable); check the age of your helmet.
Riding 2,400 miles in 7 days doesn't leave much time for exploring, and enjoying. We rode 1,935 miles, circling Lake Superior, back in 2009, spending 9 days doing it. We were two-up, on one bike, just us, no one else. We took in a lot of sites, ventured down a number of side roads which looked interesting -- and they were! I'd suggest a slower pace, to take in the sites around you, but that is just me, and my approach to touring. YMMV. Cheers!
