Make sure not to over tighten the catch on the door, or you'll never get it open again. Mine popped open on me twice in the first 2000 miles, I adjusted it and it seems to be better, we will see as I am heading out on a 2000 mile trip up to Calgary this weekend.hmd520 said:Make sure the spring is tight and pulling the latch back into place.. Also check to see if there is alot of play in the bag when you close it... it has about 1/4 " or so when you push on it.. but it should be a little hard to close. Might just need an adjustment.
