New to The Brick from Illinois

Hey all, I just purchased a 1993 BMW K75RT and will be picking it up on thursday. I'm very excited as I already love this bike. I currently ride a 97 Yamaha YZF600R, and also own a 80 CB650, an 81 CM400, and a 96 CBR600F3.

Firstly, the bike has been sitting for a little while, it runs but a little rough. I plan to change the oil, plugs, drain the gas, run some seafoam in it, change oil and filter, change fuel pump, and lubricate/change all fluids. Anything else I should do?

Also, the owner claims this was designed to be a police model, any way I could check this? It does seem to have a plug for a CB radio that seems stock but I don't know if other models came with that or not.

Anyway, so far I love the forum and am learning a lot. Hope to be enjoying the bike soon!

They shouldn't run "rough" :nono...We usually buy them because they are smooth and fast .  If it has sat "for a while" it could be a fuel problem or an intake leak (degraded rubber).  My bike had sat for a few years ( basically since 1994 :hehehe).  I found out after the deal was made. I bought the seafoam...but then took off the tank lid and found a disaster.   Anyway, renewed the entire fuel system and cleaned the tank with help from this forum, AND a new crankcase vent hose.  She was very slow to start the first time,  but has been running for 4 days now like a sewing machine.  I replaced the injectors for the same cost as cleaning them...

Congrats on the RT, I bought one last week.

Along with your list include checking the final drive splines, one of the few weaknesses of the K75 line depending on miles, maintenance, and riding style.  Simple procedure to remove the FD, check, and lube.  I bought a '92 with 37K, that the PO and service records didn't record a lube, but seemed to have had an easy life, and was relieved to find this:

In extremely good condition.

+1 on Jackgeiger's input.  A crankcase breather tube that is cracked/split can affect idle.  The tube is inexpensive ($9.95 at Beemerboneyard) and easy to replace.  On mine the area around the clamp is cracked.  Even though the RT starts/idles great, I plan to replace the tube.

Running the VIN might tell if it was a police model.
