I've had mine 18 yrs after a succession of Austrian, Czech, Brit, Italian and Japanese bikes. It's the longest I've ever owned one bike so you do get to know it and it's foibles and peculiarities. Bricks don't like sitting and rubber bits deteriorate check the pump damper and replace internal fuel lines with 5/16 SAE 30 R10 submersible line, external lines SAE 30 R8. Avoid E10 fuel it turns fuel lines and the damper into Vegemite and can get into the injectors. Electrical connectors need to be gone over and cleaned with Deoxit, I then put dielectric grease in them it keeps the air out which helps combat corrosion. Avoid staring the bike until you have cleaned out the fuel system, cooling system ( OEM coolant is cheap from BMW with distilled water) and changed the oil and filter. RBM is the resident expert on instrument conversion, LED conversion and all things electrical. I tend to go overseas for parts Moto Bins, Motorworks in the UK, Beemer Boneyard, Euro Motoelectrics in the US. Once you get it going don't be too concerned if it smokes, they tend to settle after putting some mileage on them. If it is severe you can run high detergent flushing oil for a short period. Good to see more Ozzie Bricks they are getting quite thin on the road around Brizzie.
