Alright folks, I recently bought a 2001 K1200LT from a dealership that took the bike in as a trade in. She has 20,070 miles and I paid $3200... which regular maintenance work to I begin with?...
Congrats on your new bike.
You got a 2001 with 20K miles for $3200?!
That means my 2000 with 98K miles is worth 50 cents.
I'm keeping it, it is a great bike!
You will enjoy yours.
As with any new bike, I would do a complete "inspection" service. BMW manual calls the 12K interval service "BMW Inspection" as opposed to the 6K interval "Service". Your service manual will list the items but going from memory involves all filters, valve check and adjustment if needed.
Then I suggest you just ride it. If you undertake every suggestion on this site to preemptively "fix" things you'll be wrenching and not riding.
I did a lot of stuff to my 2000 just because I read posts on this board, I'm not sure if they all were needed. You can save a bunch of time and money not fixing things that aren't broken.
Replaced clutch slave preemptively, don't know that I needed to do that. Still have the original clutch slave in my KLT parts bin along with a charcoal cannister and various other things.
Drilled the clutch housing weep hole. (Has anyone ever reported that the weep hole saved their clutch?) Although drilling the clutch housing weep hole is pretty quick and easy to do.
I still have the original starter relay; I just keep it on a Battery Tender. If you get a low battery and slow cranking, just don't keep trying, jump it or charge it, or replace the battery. I'd pass on replacing the starter relay, just observe the precautions.
I've rebuilt the final drive a couple of times. Never had a failure. Rebuilding final drives has been some kind of hobby.
If you are planning long vacation rides, a preeptive final drive rebuild is good road insurance for that year bike. (or just have a plan for an emergency final drive change out on the road).
I replaced the fuel line connectors with metal quick disconnects. That is a good idea.
Recently replaced the brake lines, but never had a brake line problem. Probably a good idea on a bike that old and given the reports of OEM brake line failure.
I'd put on a new set of tires. I'm partial to BridgeStones although I am now using the Bridgestone rear/Metz front combo since I am riding a little slower than I used to. A set of old Metzlers like you may have won't be nearly as grippy as a set of "Stones". Since you have such a great new bike, you deserve a new set of Bridgestones or Avons, they really set the bike free.
Enjoy the Ride
