1995 Kawasaki ZX-6 E Dragbike in Rogue River, OR

ZX-6 dragbike it has a tranny problem I think think it is a simple fix but without pulling it apart I can't be sure.It will still shift through the gears it just misses shifts about every 3rd run or so I have a spare motor that could swap the tranny or swap the whole motor I am asking $2200. as is. with airshifter, 6" swingarm mods, brake lines drag chain & sprockets,new K&N filter,fresh clutch, dead man switch, M/T 7" drag slick wheelie bars , paint and other parts I have over $5000 invested. This bike took me to 20011 track champion at Champion raceway in White City 11 wins 3-2nds. In cool air the bike runs 11.40s at 116 mph with a 170lb rider. NO TEST RIDES if I don't answer leave a mesage I will call back.
