I have a 07 jackpot and it is popping and surging when you accerlerate. I have read a lot of the post about cleaning the throttle body. When removing the gas tank, does it need to be empty? I noticed that there isn't an on/off swith like other bikes. I have read the owners manual and doesn't help me. Any tips for me? Also I did the throttle reset and it doesn't do anything different.
