Its a crap shoot with this Bike

Maybe the damper needs adjusting? Or check the torque on the front end nuts and bolts? Some have mentioned they found some not tight enough. It also has been mentioned that the bolts that hold the handlebar mounts could stand to be tightend up a tad ( the big ones with the rubber dampeners )although mine seem ok. Just some thoughts.

Do you have any other farkles besides the wind shield? That info might help someone provide a solution.
