Mixture: A lean mixture is felt as surging. The bike pulls, then doesn't, then does, then... Closing the throttle a bit makes it go away instantly. Many mistake a rich misfire as lean surging. I know I did.
Pods: Reconsider. Unless you are willing to invest many hours testing and tuning, or put up with a bike that doesn't run well, pod filters are not worth it. It has taken me 3 years of constant testing, adjusting, and learning to get my bike to run as smooth as stock. I had to remove the stock air box when I did my suspension modifications, so I had no other option than to use pod filters. Sure, it is now much louder, and may make the same power as stock, but it wasn't worth the effort.
I was speaking with a guy last week who is ready to sell a bike just because of pod filters. There were 3 other old-timers around, all nodding in agreement. They have all learned the hard way, and know better, now... CV carbs don't like pod filters.
If you aren't yet convinced, do a search here and read of the misery others have experienced. Also watch some Youtube videos and listen to how poorly the bikes run. Coughing, spluttering, misfiring... Still not convinced? Think you can easily accomplish what others can't? Then go ahead. Be sure to spend the $ to get good filters like UNI foam filters, or K&N. Then buy a box of quality (not the cheap knockoff) main jets, in pairs, ranging from 117.5 to 135. Consider making stacks to mount the filters onto. Then invest many hours testing, tuning, and taking detailed notes, rather than just riding.
Bottom line: Don't do it.
