I LOVE MY 98 900RR AND I WANT TO GET AS MANY HORSES AS POSSIBLE OUT OF IT WITHOUT ENGINE REBUILDING OF COURSE I KNOW CARBS JETTING AND AFTER MARKET EXHAUST WILL HELP ANYONE HAVE ANY SUGGESTIONS ON WHICH BRANDS (EXHAUST AND CARBS)AND WHAT STAGE JET KIT I SHOULD GO WITH I WANT A QUARTER MILE ROCKET!!!!!!

 

Go for a yoshi pipe with K&N filter

 

get some velocity stacks as well. The best way to feel the power is to lighten the bike up. So like a 520 coversion kit and a rear wave rotor will decrease rotating mass and help the motor rev up faster getting you up to speed quicked. That and going down a tooth in the front sprocket will help the bike out of the whole shot. Not really horsepower mods but real world mods.
