Thanks for the replys, yes I did change grips and I thought about the glue, tried again last night and it still wont come apart. I did use a screwdriver and it will completely seperate all the way around about a 1/8" but something is def. holding it. I'll continue on and figure something out, thanks for the help, just wanted to be sure it was just the two screws.
The bottom has a small tab that locates in a hole in the handlebar. It could be stuck in there a little. You would notice that if the top was trying to come off but the bottom is staying in place.
Definitely only two screws, I've had mine off a few times. There are a couple small nubs that index the two halves together, but I don't think they are even 1/8" long. If you have it apart that far you could see them.
