Air-Box & Filter Optimization (660 as example, universally applicable)

I wanted to expand on some specific facets of 2-strokes to kinda "accompany" the points covered in my reply to Iron Horse's reply (Iron Horse if you see this before I've got my reply video up I apologize, I don't know how KZbin went so long w/o serving me that video, it 1st appeared in my feed about 1wk ago at which point I just went into high-gear to get my full reply ready!) This video covers intakes, specifically going over how to keep an HD2 akin-to a Maxi (when both are new, Maxi's only have a 2% edge, it's the rapid oil-blocking on HD2's that is their achille's heel), how to prefilter either type of setup so you could even get an HD2 to outperform a Maxi, and the importance of assembly/sealing of the box.

Great tips, was just wishing I had an easy solution to oil on hd2s

Nice video, good tips. I was on the fence with max flow for similar reasons. Do you have a take on the k&n style, cold air intake velocity stack setups?
