As you can tell by all the questions I'm new to OS BMX!!
Right then, my next problem is that there is movement in my 1 piece crank. How do I go about tightening it? There appears to be a flat faced nut with two recesses and a lock nut on top of that. Do I just loosen thelock nut and tap the flat faced nut around with a screwdriver/chisel?
