Get a good set of pliers/spoke wrench and start bending them till they feel tight...or the wheel stops wobbling....now only bend from front to back as this is the front wheel were talking about here right ......( that means take the pliers/ spoke wrench and bend toward the rear wheel) Pfft!.......then when your done toing that you'll wanna get a small tube of elbow grease and rub it on the side of the rim so this doesn't happen again for a while!my son has a 90cc dirt bike and the front spokes are loose does anybody know how to tighten them.
