I did a little searching and no luck finding an answer to my question. I have a 98 Honda CBR900RR and was wondering if there were any aftermarket air filters that are good for more power. And, if going stock what is the best brand of filter to use. Being under the tank I doubt its been changed very often, and I want to go through everything on the bike. I do that with all my cars too, change all the fluids and filters as soon as I get them. Also, just wondering what kind of power adders are available to my bike. Are jet kits worth it, head work, on and on. Its super fast already but I want it to be at its best. Thanks
