"Cheap pods are just a waste of money and are more restrictive than stock airbox at high rpm"
Only half this statement is correct and that is cheap pods are a waste of money...
I have tried every manufacture of pods both expensive and cheap and NONE have been more restrictive than the stock airbox...
And this restiction (stock airbox) is how a simple, basic, non accelorater pump type carb works on these bikes.
Lets not forget, Honda was building an inexpensive, reliable, dependable motorcycle for the masses. and INMO did a pretty damn good job.
BTW, I too perfer K&N.
