hey guys have a 93 kat 600f and when i full throttle it it pulls hard from 1000 to 5000 then from 5000 to 8000 it seems to fall off a lil and from 8000 to 12000 it pulls hard again. is this normal or is something really wrong. it kinda feels like v-tec kickin in a 8000 lol thanks in advanced for the replies

 

what kind of exhaust/ carb kit/ air filters are you using?
are you running stage 3 (pod filters, no airbox)?

 

all stock as far as i know. i mean i cant tell if there is a jet kit or not there is the factory air box and factory exhaust. sorry forgot to mention that lol any other suggestions?

 

well, box stock oil cooled suzuki's always have a dead spot in the midrange. you can tune it out, but it'll involve alot of trial and error. any time you tune for one particular rpm range, you're also going to comprimise power at other rpms too. that's just the way it is. solving one problem may create others. if it's not really "choking" or misfiring, or anything like that, in all honesty, i wouldn't be too terribly concerned. all i4's have a deffinate "hit" of power at certain rpm's, some are just more noticable than others.
