Then I don't know why it's happening. Some bike / chainring / chain combos are just prone to chainsuck from what I remember when I rode bikes that have those shifter thingies on them. I seem to remember when I ran a shimano chain with my race face crank on my stumpjumper, I was more likely to have chain suck issues. Not sure what you're using for lube either. That could be the issue.
If you're gonna be dumb, you better be tough.
