LTZ 400 NEED FOR MORE SPEED

I HAVE A 09 SUZUKI LTZ 400 AND AM HAVING A HARD TIME FINDING AFTER MARKET PARTS FOR IT LOCAL DEALER KEEPS TELLING ME THAT SUZUKI HASNT PUT ANYTHING OUT YET.WHAT IM LOOKING TO DO IS MAKE IT FASTER AND WOULD APPRECIATE ANY SUGGESTIONS ANYONE HAS. DONT GET ME WRONG RUNS GREAT AND I LOVE IT JUST WANT MORE. DONT REALLY WANT TO GET INTO ANY MAJOR MOTOR WORK YET JUST STUFF LIKE EXHAUST AND OTHER BOLT ON STUFF ANY AND ALL HELP WOULD BE APPRECIATED THANKS IN ADVANCE  

just order parts for earlier years. most slip on exhaust will fit multiple years, along with different brands. my advice would be ebay. you will find whatever you need there and if you wait for the right time you can score some major deals on expensive things. also to make it faster without engine mods is somewhat difficult. and exhaust and uni or k&n air filter will give it a little more bite. tires will pay a huge part, more grip means more ground covered. also jump your sprockets. less teeth will give it more rotation. another thing that isnt very hard is to port and polish the head. it does involve small engine work but nothing too difficult. also for the 09, dont quote me on this, but i believe there is a wire that if you disconnect it it shoots the power levels way high. maybe want to google it. i think i read about it in a dirt wheels a few months back. just those small things will help alot. you might want to try drilling holes in the airbox cover too. it will allow more airflow and less restriction. im not sure if the 09's are carburated. im pretty sure they are fuel injected. but throwing a carb on it and tunning it just right will make it much faster also.
