Everything is back together. After setting the pilot screws, I re-synced the carbs again. With the engine hot, dropped the oil. The oil looked brand new when we got the bike because the PO changed it, but had never run the bike. With the minor running we have done, that oil turned fairly dark pretty quick. :headscratch: :nea:
Checked the oil and sure enough, it had gas in it from when the bike sat all those years. Well, at least it gave the engine a good cleaning. :hihihi:
Not too much gas, just enough to mix with the fresh oil to remove carbon. I flushed with some clean oil and then refilled with fresh 10W40. Pulled the filter. It is an aftermarket chrome filter housing. I did not like it much, but many like their chrome. I did not like that there is no inner lip to retain the main seal, only the outer lip of the housing. I did a test tightening with the new seal and sure enough, it slipped and the housing leaked. There is also no spring or washer holding the filter back away from the bypass holes. I will post a picture of it as soon as I can.
I searched my old '81 parts left over from the '81 diesel :hihihi: and found the oil filter housing, spring and washer!
Cleaned it up and it fits like a champ! (Maybe because this is also an '81?) :smilie_happy:
