I have a '18 R12LC with SW Motech engine crash bars attached. Other than using SW Motech Valve Cover guards will the plastic Machineart valve cover guards fit past the crash bars? Manufacturer says probably. I need to know definitively. Anyone know for sure? Also if using same crash bars are you bothering to use valve cover guards? I had a near tip over in gravel and realized the rocks would still damage the valve covers even if the crash bars prevented structural damage.
