Hi all,
Got a used BJ4 WE coming for an event I am doing here in Calgary, and as some of you know the track here is rough with some HUGE jumps.
My problem is, that as far as I know, no one else here has a BJ4, so I won't be able to scrounge any parts, so I'm on my own.
So, what has anyone broken? or what wears out?
Basically what should I get in the way of spares?

thanks
Stu
