Second Air Assembly Needed?

[Drake747]

Hello all, i recently purchased a new engine for my gs. I noticed two pipes coming off from the lower cylinder head just below the carbs and realized that my old engine doesnt have that, what my question is, could i just plug it? Or do i need to run that second air assembly. Thanks

you have a 500f motor and the ports are part of the pairs anti pollution system
you can make up some plates and block them off without causing any problems

what should i make the plates out of? is there any other way to block them?, like just plug it somehow?
