a clip came off the needle in my car last weekend n went threw the clutch side jug of my 96 xcr 600 sp.[xx(] i got another jug n looked at the two. n noticed somthing wrong. i measured the bore of my new one (63.5) n the old one (65.5) so i took it to the local sled shop n was takin to my friend. the first owner of my sled was a competitive drag racer.(im the trird owner) so we called him up n and asked questions n told him our problem. we finaly got it out of him that the jugs were off a 680 ultra. my friend told me that the 680 had more nuts then the 700 xcr. what do yall think of the 680 ultra?
