Off road motor bearings
 

Do off road racers use any special techniques to deal with the extra grit and dirt that oiled motor bearings attract? Should I be running shielded bearings on my mod motor? Anyone try sealed bearings?

i run on a verry loose and dusty track I dont use any thing special i just make sure the berring is well oiled before every run and after each run i fully disssasemble the morot an thorugly clean it

they really dont collect that much dirt
