Grip problems

[pburgess]

I've got an '02 gz250 that's been serving me well for the past 3500 miles that it's seen in the last 7 months i've had it. just put on a new rear tire and was looking for some new grips while i was at my dealer a few days ago. found some gel progrips and after quizing the salesman to make sure they'd fit, i went over how to change them with him even though i figured it was a completely mindless swap. i figured the whole soapy water thing out but after getting them changed, i put the sliders back on and they wouldn't screw in. turns out the fastener inside the handlebars worked loose and now won't screw back together. which means they're also stuck about 2 inches inside each end of the handlebar. so anyone out there have any good ideas for getting them fixed without sending it to the service dept. at my dealership, seeing as they couldn't even warn me of this in the first place.
