This bike is stock except for the aluminum skid plate, bark busters and, the extended carburetor vent tube. The pilot jet was changed to the next larger size. I purchased this bike new for my oldest son, riding was not his thing so the bike spent most of it’s time in the garage. My youngest son expressed interest in riding, so I replaced the tires and tubes, he probably rode the bike six times that season on very easy trails as you can tell by the pictures the tires still look new. $850.00 BRO
