Motorcycle Repair: Oil Spilling Out Of Alternator, rotor stator, carburetor jets


Question
I have a 1974 Honda CL-200,  I have recently purchased this motorcycle and it does not seem to want to fire... We are getting sparks on both plugs, so upon researching upon how to adjust the timing we found ourselves in the alternator case.  When removing the alternator case lost a good quart of oil.  Is this normal for my model bike.. it stops spilling if the bike is upright on its centerstand but regardless oil is residing in the alternator encasing..  Is this model supposed to have oil in the alternator case.  Thank you for your help in getting my bike running...

Yes, the alternator windings do run in oil, to help keep them cooled off and to minimize the size of the engine. Keeping the bike on the centerstand will reduce loss, but when you get done and the dyno cover is back on, then check the oil level before you fire it up again. Just DIP the stick into the hole, DO NOT screw it back in, to check the level. Add, as necessary.

When you check the spark timing, be sure to verify that the mechanical advancer is free to advance/retard. It is located BEHIND the point plate on the end of the camshaft.
Points should open at the F mark alignment of rotor/stator index mark. Maximum gap should be about .014" when turning the engine over with a wrench on the rotor bolt.

Check the valve clearances, while you are in there digging around... .002" for intake and exhaust, when valves are closed on the T mark alignment. Check the side that is loose, revolve the engine ONE turn and check the opposite cylinder's valve clearances.

If the spark timing is set and you have a good spark, and it still won't run, you could have partially fouled plugs or your carburetor jets are plugged up from sitting.
