I can't speak for the Lama itself but two
things you want to be sure of:

1. lubricate the bearing w/ a light oil, not
a thick grease.

2. Always make sure to clip off the fuel
supply (ie. do not allow the engine to flood).

In some machines, they use a 30 size bearing which is marginal for 46 use and
when you try to start a flooded engine,
it just blows out the bearing. Ask any
TSK46 owner about that.
