The vinyl toolkit bag that came with the bike was neglected and has self-destructed.

Does anybody have any ideas for something to hold the tools and that will fit under the seat.

I have several of those bags from other bikes laying around. PM me your address and I will send you one.

hell, im lookin for tool kit for my GS. im never lucky enough to get tools with a bike.

Find a smallish rollup toolbag, the kind they put wrench sets in.  Vastly superior to sliced bread, and better than the stocker too...
