no worries. but if you want to keep that bike and set it up for fmx you could. itll just mean you have to do some work to it. but if your like me and love doing that kinda stuff its all good. first you wanna strengthen the frame, then stiffen up the suspension by either getting harder sprins, spacing the springs with washers or adding more oil until your satisfied with the stiffness of the fork. but putting more oil in than recommended can mean you can burst a fork seal. then get ya self a fastace,DNM etc. rear shock n throw it in. you might have to put heavy duty hubs in aswell and heavier spokes then you might wanna do some engine work eg, carby, porting, irk, bbk, or just get yaself a 140 and throw it in.
