What are good port durations for good low end power while still keeping good top end speed?
I’ve heard between 110-130 intake, 150 for exhaust and 120 for transfers. Thoughts?
Also my 66cc iron sleeve transfers are not flush with the top. I heard it’s good to fill the empty space with JB weld so it’s flush?
