Thanks for the replies guys
Checked the front sprocket this morning and it's not hooked at all; there's a bit of play when pulling the chain away from the rear sprocket - I'd guess 3-4mm, but no chance of jumping off (assuming I was doing what you described in your post Jake).
Jake - sounds like you abuse the hell out of your front sprockets...LOL.
Eric - do you still live in this neck of the woods? 13-14mph average speed is quick compared to what I usually average on most of the trails in Tillamook, think I'm around 8
I'm going to get a full kit ordered up and have it on hand, my guess is I'll be swapping everything out in the next ~20 hours or so.
