Hey guys sorry to keep bringing this tired question up. I just put a FMF full pipe (powercore IV-2) w/ header on my 2000 ex and have a couple of questions.
1) What's the long crome aluminum spacer for ? (the instructions refer to using it on the rear mount, why?)
2) I also bought the K&N Jet kit w/ filter. Should I do a stage one or stage two jetting ? I'm not doing any other engine mods to this machine.
3) Anyone have specs on how tight I should wrench down the head bolts ?

Thanks guys/gals....

Jeff
