Hi from Georgia. Got a non-running scooter and I'm getting it back in shape. It's a 2016 IceBear Ghost 50cc. I'm a Jeep and vintage outboard motor mechanic, so the two-wheeled stuff is new to me. Fun learning, though.
I just chucked the old motor and put on an out-of-the-box GY6. All is good, but what is this line coming out of the intake manifold area with the forked, Y-shaped line fittings on it? The old motor did not have this line.
