Hey all... Just started up the 125 to prep for winter. I noticed exhaust coming out of the power valve breather hose. I never noticed it before. Is it normal? https://youtu.be/sTmsnXiDI-g
I suppose some seal in the PV assembly has gone, allowing exhaust to escape into the forward housing of the cylinder.
I doubt it has a negative effect, but I would be looking to fix the seal before it gets any worse. Someone with more experience will chime in.
-BIG DAN
From a quick diagram search I discovered I have no experience with this style PV.
