96 GSX Went riding for 2 hrs this sunday. Notice when I go faster then 6500 rpm it will just drop rpms and if I stay on the gas it will die. If I get off it drops to 2000 then I can jump back on it. If I run it at 6000 rpm or less it runns great even once in a while it it drop to like 4800 but recovers back to 6 in less then 5 sec. I have been having rave issues but they did not stick this time out. so was thinkinng mite be getting air in system or trash some place.

Anyone have any other Idears?

NEW motor with 11 hrs on it since rebuild 2 tanks of 32:1 with 1/4 tank left of the 2nd tank. gray line are gone, fuel filter is clean.
