GY6 50cc
I have a couple concerns on this GY5 50cc motor i bought off ebay for a little project.
Im curious on what this port is for on the front of the engine http://i676.photobucket.com/albums/v...35482994_n.jpg also Im curious what are the 2 vacuum ports are for on the intake elbow. http://i676.photobucket.com/albums/v...11589742_n.jpg Thanks guys! |
1. Part of emission control system. A lot of folks remove this stuff, then make and attach a block off plate to the opening. There are part suppliers that sell these plates, but they are easy enough to make.
2. Vacuum ports are there to operate fuel petcock/pump, and the ACV/anti backfire valve on the right side of carb. Some manifolds have just one nipple....doesn't matter either way, just cap off unused ones. |
