I am new to this site but many people have told me how helpfully it is so i decided to join. ive been having a problem with my busa lately. when ever i try to give the bike throttle it hesitates or bogges and then it gets power. many people told me that it was the spark plugs. when i switched them out, i found that the bike was running to lean. i switched the plugs out and now the busa is hesitating worse. what can the problem be. thanks for any help.
