i figured it out it was in the design of the bike "how the carbs are mounted", "downward" so that they dunp gas into the motor the factory had a problem with this so they recalled all bikes with a defective fuel cut-off valve. when this did not work the cylinders filled up with gas. when this happened there was no possablity for air intake. it striped out my starter clutch assembley and i had to take my motor apat it was hell --Anthony
