i bought this 2000 busa almost a year ago .the bike was set up for racing and street use. Well shortly after then engine spun a bearing so i purchased a 2007 engine with 4000 miles. i swaped the engines and returned all the racing gear back on the bike except for the nos system which i did install back on the bike but left the bottle off. it has a four tube spray Bar system in the airbox .now i realized during the engine swap the airbox did not have an air filter so i installed one in it. the bike ran absolutey great. i did notice a few airbox mods (like the flapper was removed).once realizing the engine was running great i decided to put the bottle back on and take it for a spin. and yes i left the airfilter installed. well i proceded to hit the nitous and it took off likr a rocket but it back fired pretty hard and blew the airfilter all to pieces. this resulted in airfilter material to be sucked in to the intake. now the bike wont idol and is loading up. i have changed the plugs four times since and still no change. i did a chem dip on the valves by filling each cylinder full to clean the valves. after this i sucked each cylinder dry changed the oil and filter and replaced plugs once more and still no idol and it is sputterin while goin down the road.but seems to rev up fine while sitiin still .i had to turn the idol screww way up just to keep it running at 1500 rpms. but i did noticed if i unplugged the fuel pump the idol jumps up to about 3000 rpm and seems to run smoothly til it runs out of gas. im so confused on where to start.i know i should of just left the bottle off. but i know that now . i just want to get my busa running again. can someone plz steer me in the right direction.
