Well my bike is suppose to have a power commander and i dont know much about them, my friend has one on his gsxr 600 and it is under the back seat, I cant find mine anywhere on the bike, can you unplug them once you have set the computer on the bike like a car? just wondering if i need to buy onee now that im not sure if its on there, thanks

 

the power commander is normally placed in the trunk under the seat.
if the seller told you there is a pc and you can't find it, call him and ask. may not have been installed at all.

i don't know why anyone would place the pc anywhere else besides under the seat.
