i think the oil is coming from the back of the motor. i have my bike sitting flat i never stand it up. could it be elevation change???

i would go 4 mil for more power. boost bottle doesnt do anything u dont need it

while on my way to Glamis from san diego my banshee leaks oil, and on the way back what could be causing this problem anyone?? and i got a light problem one of my trail tech lights always burns out after one ride ,why??

i put a 421 cheetah in my bike that will beat those 450s. still good for duning too
