In this video we throw some aluminum shavings as I first weld up the fabricated intake manifolds before port matching them to the heads for improved flow! I didn't remove a ton of material but rather increased any tight radius and gave a general cleanup on the port surfaces both intake and exhaust which I didn't show. I was careful not to open up the ports so mixture velocity would remain high.
This GL650 engine should be breathing really well with the Mikuni VM34 carbs and stainless exhaust! Keep an eye out for the engine assembly videos to come!
