I recently had to have my engine replaced.
There was no oil in it. It was my fault for not checking the oil before each ride but it is such a “pia” to pull the seats and cover just to check the oil.
I changed the oil and filter in December 2017, rode only 500 miles and the engined died because of no oil in August 2018. It wasn’t burning oil that I could see or smell. The oil filter and plug were tight and there was no oil anywhere on the engine. The mechanics could not find any cause for the loss of oil.
Today when cleaning the air filter I found a lot of engine oil the air filter case and soaked into the air cleaner foam.
Any ideas as to the loss of oil and the oil in the air cleaner?
