Maybe a bit more difficult on a murdercicle but here's how I do it on a car=
. Charge the battery so it's at least 1/2 charged, then take the negative c=
able off the battery. Put a test light between the battery post and the cab=
le end. If there is a drain, the light will light. Now start removing elect=
rical things until the light goes out. (On a car I pull fuses one at a time=
.) When the light is out you know which circuit to tackle. That might be en=
ough to get you started.

Not a roadster-specific question, but related to vintage vehicles (my '72 Y=
amaha): Any tips on tracking down the cause of a battery draining down near=
 flat after a couple of days of sitting? New(ish) wet-cell battery, just to=
pped up the acid this Friday, charged it up. On Saturday the bike started, =
ran fine (after I cleaned a couple of fouled spark plugs =96 two-strokes, y=
ou gotta love 'em), but went to try it again this evening and it barely lig=
hts the neutral light.
