Big port head vs small port heads?
Well i have the Lifan,.. Its closer to a GX390 than a Loncin Predator,.. The 2011(ish) and on GX390's are UT2,.. CDI ignition AND small port heads vs the previous UT1 big port heads,..
The Lifan utilizes the CDI ignition,.. But from what i gather DOES NOT share Honda's thinking in going to the small port head,..the Lifan is still the large port head..
What are ya'll thoughts on this?,.. I'm in cam selection mode and just when i had settled into a decision, NR's 280TQ, i stumble upon the head information,.. Obviously this needs consideration in cam choice,.. Thoughts?
(And thank you)
