Dumbass who put NOS energy drink in his bike thinking it would improve its performance. Guy originally posted on a GSXR forum (user sti2gsxr), and may or may not have posted as a joke. Nonetheless, its funny as hell because, someone, somewhere has done it.
sti2gsxr is forever know as "nos guy" after he put NOS energy drink in his bike.
