I put the Kleen/Pair/remove AIS/remove smog crap or whatever you want to call it. I took it out this morning and it ran fine, but when I shut the bike off the tank is now whining. I pop the gas cap and it equalizes the pressure with no issues. The cap vent didn't change, so I doubt it is that and I checked the vent hose on the left side of the tank and it seems fine. Anyone else see this?
