Hi guys and Gals,

I usually hang in the VA and MUG rooms, but a guy I know has a 1985 BMW K100RS for sale for $2500 w/ almost 100K miles. Seems in really decent shape considering...only a few scratches and missing the right side mirror. Has the fairing, hard bags, decent rubber.

I understand these bikes will smoke a little, especialy on start-up, but this one seems to be a real smoker, yet it pulls very strong and engine sounds smooth. Anything on this year/model I should look out for?

These bike usually smoke at start up if left on there sidestand overnight. The smoke should go away quickly after starting.

You might have the guy leave the bike on it center stand overnight and then try starting it ( it should not smoke)

Cons about this model, if he still has the complete fairing on the bike they are very hot (warm) when riding. Service is a bitch as you must lube the trans splies and drive splines every 40K to do this the bike must be split in half (big job) usually runs about $500 off the top of my head.

At 100K the bike is getting twords the middle of its service live as I have heard of these bike running 150K-200K+ before needing a major motor rebuild.

When these bikes are left on there sidestand overnight you will get smoke on start up (very common) but if it goes away quickly after riding and continues not to smoke its should be ok.

If you determine that the bike does not smoke when left on its centerstand overnight and the guy does not have all service records or at least the service record for the spline service and valve shim check I would take a pass on the bike.

My favorite of the brick line is K75s as they are extremely smooth motor ( the K100 - K1100 line does have some vibration in the handlebars) which I hated.

Spline lube is more often than that but once you do it it gets easy. More like every 15-20K I think. I always have had R bikes but the K1200R is really calling me........I agree that you should center stand the bike and see if it smokes. Also you could get a nicer bike with a lot less miles for not too much more than that. Be patient and keep looking!

My Buds' K1200RS is a nice bike. Keeps up w/ my 2003 SuperHawk easy.
I *like* the loudness button!
