Air Filters

I think general consensus is to keep the stock airbox on an old four like that. Cone filters, while not impossible, are tremendously difficult to tune. If you need an airbox I have one that is in great shape! Plus a whole bike for parts if you're in need.

Due to the difficulty or for the main idea for the engine to feel well? Seen many bikes with the cones and looks great, but I understand that it's difficult to tune. Seen some vids on it regarding the vacuum. Is it that big of a problem?

Thanks for the tip and offer, but I'm situated in Sweden so I believe that it would be a hassle getting the parts here, hehe.
 
It comes down to uneven air flow and restriction. Installing cone filters on an inline four means you have a lot of turbulent air coming from all different directions into tiny individual filters. This means all four carbs are constantly getting an uneven supply of air. The purpose of the airbox is to collect and still massive amounts air so your carbs can breathe easy. If you're well versed in rejetting carbs or you know someone who is, by all means go with pods, because they do look sweet. However, if you want the bike to run well right off the bat, find a way to make your stock airbox look awesome. Or fab up a new one!

I see! Thanks! Sounds correct. Think I'll have the box for now until I meet someone who knows this better than me!
