. . . I would do the following:
Bike Prep - complete flush and replace of all fluids if this had not been done within the past 2 years; bleed clutch and brakes; tire tread check; brake pad check; shock absorber check; clean and re-grease every element of the shift linkage; check all lights (including those on the dash to make sure they work); check that all heating elements work; check cruise control operation; check that throttle cables operate smoothly and normally; check condition of windscreen and that it operates smoothly; check that mirrors are attached tightly and that they are tethered properly; check for vacuum condition in gas tank; check that gears operate normally, both up and down.
Rider Prep - join BMWMOA and get Anonymous book; get boots, riding pants, riding jacket, riding gloves that are appropriate for weather conditions; check them carefully if you already own them, and fix the "little" things like a baulky zipper (these will become "big" things during the trip); think carefully about your choice of helmet - will it be too heavy, too hot, too noisy, too uncomfortable to WANT to wear for multiple days in a row, 5 - 10 hours per day; check condition of helmet parts - shield scratched, chin strap loose or frayed, interior smelly, lining ripped, etc., and fix/replace problem parts (or buy a new helmet); put out on the bed all the clothing you think you will want to take, then examine it with a critical eye - do you really need 6 pairs of cotton underwear, or would you be better off with 2 pair of synthetic, one to ride in and the other to wear when you wash/dry the first?; remove everything that is not necessary, and then examine the remainder with the same critical eye; put out all the ancillary stuff - spare eyeglasses, sunglasses, lip balm, sunscreen, helmet liner, flashlight, spare key, BMWMOA Anonymous book, maps, travel guides, reading material, journal, pens, computer, toiletries, medicines, cell phone, PDA, etc. etc., and then remove everything you don't truely need; assign EVERYTHING to one packing location (e.g., left case bag, main compartment) and then pack to make sure that everything fits (+1 on the Space Saver bags and baggies); take yourself out for a shakedown ride of at least 2 consecutive 500 mile days wearing all your gear and with everything packed on the bike, and honestly appraise both bike condition, gear condition, and your condition at the end of each day; begin to build neck strength (exercises and/or wearing helmet for increasing lengths of time) so the helmet does not give you stiff neck; decide how you will maintain hydration (+1 on the camel back or another water holder called the Platypus. They both have a tube from the water holder to a valve that you bite on to sip water on the go; go online to www.Campmor.com
for one source) and then practice using the hydration method during your shakedown rides; decide how you are going to handle a flat tire (if you decide you will fix it yourself, obtain the gear and practice plugging the hole and inflating the tire if possible. If you buy the gear from your dealer it's a good bet that he will give you a used up tire that was removed from a bike on which to practice plugging holes. You can practice inflation by letting all the air out of one of your tires and then inflating it.); decide if and how you are going to structure your riding day (+1 on 100 miles, rest stop, 100 miles, gas/rest stop); plan your route using maps and (if so inclined) gps/mapping software, but keep telling yourself that this plan is tentative and that you will change it during the ride; take a spare credit card (hidden somewhere other than your wallet), and numbers to notify credit card companies of a lost or stolen card; notify your main credit card company that you will be traveling and charging purchases in multiple states; carry a spare key, and consider hiding another spare on the bike itself; enter into the gps (if using one) all of the BMW dealer locations that are in the states you will visit.
Now go have a hell of a time riding, and remember that we want a trip report and pics.
