I own a husky CR 250 1999 model. This bike has a cover on the airbox wich I always put back on when servicing the filter.

Last weekend the cover came off when riding, I didn't noticed at the time but noticed that the bike was running a lot crispier. When I got back and lifted the seat the cover was completely off.

My question is if removing the cover improves breathing noticeably and if that is the case if any alterations to jetting might be made.

Thanks in advance.
