PURCHASED A SINCLAIR LX 150CC SCOOTER (BIG CHIEF BRAND...NOT LISTED SO I CHOSE BIG DOG BRAND) FROM GS MOTORWORKS JUNE 2006. HAD MULTIPLE MECHANICAL PROBLEMS WITH THIS VEHICLE AFTER ABOUT 500 MILES - MOSTLY INVOLVING LOOSE BOLTS OR BOLTS THAT WERE INSUFFICIENTLY SIZED TO FIT IN THE VEHICLE'S BODY (CAUSED RUINED ALTERNATOR, COOLING FAN, LOST EXHAUST MANIFOLD, ETC.). FILED MULTIPLE COMPLAINTS TO THE COMPANY AND PARTS WERE REPLACED THROUGH TIME. IN MARCH 2008 HAD COMPLETED YET ANOTHER REPAIR ON THE BIKE (FAULTY CARBURETOR) AND TOOK FOR QUICK TEST RIDE. WHILE RIDING, A BOLT CAME LOOSE ON THE KICKSTAND, KICKSTAND CAME OFF, KICKSTAND LOCKED UP REAR TIRE, BIKE THREW ME ALOFT. I INCURRED SEVERAL INJURIES INCLUDING SPRAINED WRIST AND BACK, CUTS, AND ABRASIONS. ELBOW IS STILL NOT HEALED (MAY 2008). LOOKED UP THIS PROBLEM ON INTERNET. MANY COMPLAINTS ABOUT THESE MOTORBIKES DURING THE SAME TIME I PURCHASED MINE. SAFETY IS APPARENT CONCERN FOR THOSE INVOLVED. *TR
