I'm riding a 1990 BMW K100LT with 80,000 miles. I've slightly modded it for comfort. These bikes are notorious for blowing hot air on the driver all day.
I removed all the fairings and it's made a world of difference. Twin headlights from a Yamaha sport bike, plexifairing, $15.00 wal-mart driving lights and a rear topcase from a 1984 Goldwing.
My final drive was pretty knackered, so I found a used one complete with drive shaft from a K75 for $200 shipped. BMW wants $1500 for the final drive alone, so I got a great deal. The bike accelerates much quicker now as it has different gearing. My revs are a little higher at speed, but still plenty of power and you can't beat the price.
New tires, and changed all fluids. I'm set to go - mechanically.
Trying to bring everything is tough. Swap a pair of jeans for an extra lens? Pants liner sacrificed for jacket liner? You get the idea. OK. I'm packed. 1 more day....
