Sparky,
Great find! Best thing to do is to remove the motor from the casting. Just back out the screws, and the motor will drop out.
Back out the screws holding the brush plate. Clean the armature commutator face with a pencil eraser until its all shiny again. Then using a toothpick, clean out the slots between the commutator segments. While you've got the brush plate off, clean out the brush tubes too.
And while you've got the shell off, you might as well spray some TV Tuner Cleaner into the E-Unit.
Lightly grease the spur gears, and oil the the axles on the front and rear trucks. Reassemble and play!
For Smoke Fluid I recommend JT's MegaSteam. Their new"Nada" scent is scent-free and smokes up a storm!

The 8900 is a good runner but not a very good smoker. So a little smoke fluid will not be noticed that much. Or when you take the chassis out unsolder the smoke unit ground wire or add a small on/off switch.
