Eh? Can you clarify the question please? Looks like you have an 04-07 model, which has the exhaust "flapper" valve with the pulley situated under the rear of the bike I think.
Sorry, not sure what you mean by reset it. Might be able to help if you gie a few more details.... Why do you think you need to reset it? Is the cable connected? Are you getting an error code (flashing light) on the dash? You might just need to turn the pully wheel so it's in the standard position.
