If there is one mod you must do, its the FCR carb... I dont know if it makes more power, but the throttle response is 1000 times better and the bike feels like its awakened. Not sluggish and slow revving, it feels like it should. I also installed my Akra full Ti pipe and that helps as well. The pipe is so damn loud, PERFECT! I cant wait to go riding this weekend. I love SMs now... I already know the next one Im going to get and if the dealer in minneapolis doesnt sell theirs i think I'll buy it by the end of june.
