ya toomey has 6 clips just took mine out and put a stock one in never looked back easier to tune and flat out runs better with the stock one over toomey imo
id take em apart and clean them and set your float height. if ya dont have a clymers manual suggest picking one up. sometimes leaking is theres some dirt and gunk on the needle and seat
you can run them but IMO there more like drag pipes then anything good for trails id get some t-5s if your doing trails unless ya looking for a smother hit of power get some pts or something smiler ive got t5s for trails and love them
ive got some sitting here i pulled them out and put stock needles in made one hell of a difference pain in the ass to turn with toomey needles but if ya wants some toomey needles ive got some right here for ya
