Karting??..

Since the seat is inda way I can't see the clutch/chain area. Chain guard suggested. It really sucks when the chain snaps and whacks you upside the head :lol:. Some tech guys won't even let you on the track without one.
These are good investment too Rocket Sprocket Guard Saver
Driven sprocket probly the part of the kart closest to the track, this will contact the ground before the sprocket and with any luck will keep the chain in place.
Yep. I think it has one on the engine, or at least looked like it did in a previous photo, but it needs one on the rear sprocket.
