I started to change the oil in my Yong Heng today. I am switching from Royal Purple to Husky full synthetic oil. After draining the RP oil and flushing out the old residual oil with the new Husky oil - (Husky full synthetic is clear) - I noticed that the oil level sight window has a dirty oil film on it. Flushing with the new oil did not remove the film.
I would like to clean it. Has anyone removed the sight window? Is it threaded into the casing cap or is there a retaining nut on the inside? I could take the case end cap off but have read that the sealing gasket is a pain to get back in place.
