At first I thought it was the RM2 so I dismantled the base gave it a thorough cleaning but still to no avail. Then I switched toppers and used the origen. Side flavor was still there. Changed bottle and was still there, hence I knew it was the 510. Anyway I found out that the silicone gasket is removable. Gave it a good wash and seem a that the side flavor is a lot less now. Gave 510 a good cleaning as well. Noticed there's some glue like substance keeping the brass cup to the mod? I think I don't wanna touch that right? Lol.
Anyway the original silicone gasket I saw from t rebuild kit is semi transparent but my current one is a horrible dark brownish color which one wash off. Not much side smell left though. Should I change it?
That being said, yeah seems to work fine without the white ring. Lol. I learnt a new thing abt my REO today, cleaning the gasket. And to think it was being shelved for abit because I couldn't get rid of the side flavor.
