Hi guys first of all GREAT site! I was hoping someone could tell me where i can find the det (knock) sensor on a 04 700 classic please? Im not sure what it even looks like lol i read on a post somewhere i had to pull the seat and the gas tank off to get at it as opposed to pulling off the head. would this be accurate? can i even see the sensor from jus having the bonnet up? I need to test it as i think its faulty, i believe i just unbolt but leave it hooked up and go for a run and see if the problem clears up? Any info on this issue specific to my sled would be great! thanks for any help guys and happy sledding!
