How can I diagnose this problem? My blaster dropped power when I'm in like 4th gear roosting....if I'm in some slicker terrain and I'm snagging gears in powerband and the tires are spinning once I get into like 4th maybe fifth sometimes....the power drops out and I need to downshift to get it back....shouldn't I be able to just keep em spinning thru all gears in the band and not have a issue? Can it be a air mixture prob? Or jetting?
