Re: 1000rr 08 where do throttle cables go?
I would always use the old cable to thread a new cable. To be sure to get it routed correctly. First replacing one cable, then replaceing the other.
I have not done this myself on my cbr1000rr08, but after a quick look in the shop manual it looks like you will need to remove the top shelter, lift the tank and remove the air cleaner housing to get to the point where the throttle cables are attached to the throttle body.
And what happened to the old throttle cables. It is a little early for needing new ones.
