Hey guys!
Almost done with my project of building a board track racer with a Zongshen engine. I have a some questions that maybe one of you could answer.
1. The port near the spark plug on the cylinder head. What is it? I see in some pictures its blocked off.
2. Two vacuum ports on the intake manifold: what would they typically be routed to?
3. Crank case vent hose: Where is it routed?
Here's a pic of my bike. Thanks guys!
