ive been having problems with my 94 f2 jerking when i hit aboujt 50mph and above. then when it warms up it seems to do it at all rpms when im steady on the throttle. i just put 126 jets from dynojet which it recomends for k&n which i have and exhaust which i have a full vance and hines. the main jets that were in it were 138's!!!. im hoping it will run a little better. im wondering about the 2 tee fittings on top of carbs by the needle housing. the one in the middle goes to that big rubber hose that goes to some plastic box thing on airbox. the tees on the left and right of the middle one with the big hose have no hoses on them. its just open fittings. im wondering if that has something to do with the slides opening up
