My first Oil change

Today was my first oil change since getting the bike back from the mechanic.  He did put 2.5 liters of fresh oil in when replacing the oil pan gasket, but used Castrol GTX 20W-50, and I want to switch it to Spectro Golden 4.  I will also be inspecting the oil filter, o-ring situation.

After draining all the oil, I re-installed the oil plug and decided to focus on the filter.  I will not be removing the oil pan, screen, etc since the oil pan gasket is brand new, and I do not have that ordered yet.  After the air filter nightmare, I will be doing a full oil strip down this winter.

My 77 R100 uses the recessed oil cover, 

can accept the hinged oil filter, and I will be using the advice on Anton measuring the depth of the canister, and deciding whether to use Shim and paper cover gasket.  GREAT ARTICLE HERE, http://largiader.com/tech/filters/canister.html

Removal of Old Filter

When removing the oil cover, there was a paper gasket installed.  When I removed the oil filter, the previous owner used a BMW purolator long filter, non-hinged.  The metal shim was installed against the face of the cover, and the o-ring which was red, was snug up against the canister edge.  My version has the older sharper edge canister, and the o-ring was marred with marks of the canister edge.  He basically installed it backwards.

New Installation

I installed the hinged filter, 

metal shim, white $2000 o-ring, and then cover, leaving off the paper gasket.  I do not own a caliper, and could not measure the canister depth, but after reading Snowbum's article,which sows it is rarely used, and most likely would always be better off without it, I left it off for now.  I will keep my eye on leaks, etc.
