Hey everyone, thank you in advance for any information shared. I have a 99 yamaha beartracker 250 that I am restoring (not to oem specs). I am having trouble finding suspension parts other than ball joints. Does anyone know where i can find shocks/springs for this atv? Are there other yamaha atvs that have interchangeable parts? Or what options might i have. I typically use this quad for hunting, getting around the farm, and trailriding. Thank yall again for any info. The trailriding includes moderate hill climbs, creek beds, and wet/dry trails
