Need help, ASAP

08 Zx10r, Boggs like nobody's business. Won't go past 35mph with the throttle about 10%, any more throttle and it just Boggs down. I have already checked the plugs, fuel pump, could, injectors, etc

clogged/dirty injectors will cause a skip/light miss idling progressively getting worse as more fuel is required acclerating. can tell u there is no good way to ck a fuel pump, those no load flow tests mean nothing. ur describing a operating fuel pump with just enough pressure to crank and support partial throttle low rpm. if bike just bogs out smoothley/refuses to accept throttle, it is the fuel pump. there are some new direct replacements on e bay that work well. simple to install. i've used several on stk bikes. also that pump housing the fuel pump is in is a large fuel filter housing that should be checked. basically shake all the fuel out, give it a few minutes for fuel inside to evaporate and if u can blow thru it easily it is not a problem. replacement pump will get u straight.
