Hey everybody

Are 4x20mm diameter holes if the front slope of the airbox lid the best option for a standard mc21 running a HRC box wire splice and TYGA end cans ?

Thanks guys

I used the search button and found 138 listings. Give it a try, as there are quite a few years of material
This was quite informative http://www.nsr250.net/forums/viewtopic.php?t=9161&highlight=airbox+mod

Thanks Rob !!!

I also used the search button and from what I can gather, 4x20mm diameter holes in the front slope of the airbox lid is the way to go. I am just hoping for clarification from anyone that may have done more recent testing that the 4x20mm holes in the front of the airbox is still the ideal option ?
