started tearing apart my bike lastnight to begin the the repairs for alaska, siscovered somthing odd when i got to the air box removal. my bike has no air filter of any sort. i just bought it this summer, and it's always run pretty well (it developed an odd stumble below 6k, but only at part throtle). i was just kinda suprised to find no air filter, makes me feel alot better about deciding on KandN pod filters. kinda spooky, just hope nothing too bad has gotten in there that i'm not aware of yet.
the last owner was probobly too cheap to replace a $10 filter....there is no way you can tell (at this point) if there is damage inside the engine but if the engine is running good then don't worry about it...put on a filter and ride...it's a good thing the gs airbox is in a hidden place unlike the new sportbikes who have air intake tubes at the front and pick up bugs and all kinds or small rocks when you ride them...now imagine if one of them didn't have a air filter :guns:
keep the air box, if your going to ride LD, you need to have it, your going to ride in rain, and lunchbox filters are worthless in them. if you put a uni or a aftermarket drop in you will get almost the same gains as the lunchbox. also with the lunchbox you change more than a couple thousand feet of elevation and it isn't going to run for crap. till you rejet it. with the air box the bike is going to run alot better and be alot more tolerant of un-tuned carbs and out of spec valves. you can't run her that way with the lunch box. the only reason I can see to ever put one on is if you do alot of short rides, (less than 2 hours) and just want to keep the rocks out.
Either that or they thought they could get better intake performance by having no filter at all. Some kart racers will cut out the end of their K&N filters and throw a precharger over it to hide it...it's called a cheater filter.

Also known as the Ring Eater, as you will be replacing piston rings every race.
