Problem with part after helix

I just made a helix, and on the track immediatly after the track does a wobble and I can't for the love of god find out why it keeps doing it.

Anyone have a fix? Incase you dont know what I'm talking about below is a screen shot of the piece of track in question. The helix itself banks back to 0 degrees and then right after for some reason it banks itself a tad in the opposite direction.

try to make conroll active, when it is already active, then try to make it not active

Yeah - that looks exactly like what I call "Anticipation Roll." Activiating the continuous roll on a node (vertex, sry...I call them nodes) that is supposed to be banked to 0 degrees will cause this. The problem here could either be the node at the end of the helix or the node right before the break run. Anyway, like roelywoely said, uncheck the con roll box & you should be fine.
