Review on 💙 ModQuad Decompression Plug - Ultimate Decompression Solution in Blue Anodized DP-1BL by Travis Carter

Install it on a Yamaha yz450f I think some plastic has fallen off, not sure but it wasn't there when I checked for an oil leak. But it was a good fit, oil was included, don't know if that should be included with the original part from the factory? But when I wanted to install a new one, nobody was there. I don't know how it works as I'm not an owner and couldn't figure out what type of oil it needs, but I check the bike whenever I go to the guys to work on something else and it seems fine to work, not sure about the rest of the bike but the fork is fine. (I think someone put the wrong oil in the engine who hasn't had time to look at it yet)
