I just posted a thread on info for the opened up air box side panel- you stated you prefer a stock motor, but went with the opened up side panel- what is you opinion on the preformance gain from this mod?
Yes... however, I left the inner baffle/snorkel in the airbox. The one that is to the backside upper corner. Why? well... when removed, it's a scoop for sand and silt. Since we left it, the side panel aids in fresh air. A give and take if you will.
... plus it looks cool.
On the other hand, I'll let someone get scientific for ya on your question. As it doesn't really pertain to this bike.
