Looking for part number 17517-MB6-000 (2) for a 1985 VF1000FF - the rubbers go on the supports on the front of the tank for the upper fairing cowl to slide into.
i am also in need of 1 if anyone comes up with any.
I can suggest an improvised solution.
Wrap couple of layers of duct tape on the tank extensions, enough to fill the gap on the cowl and place a cut of bicycle tire inner tube like a wide rubber band on top of duct tape wrap and staple/glue the front of tire tube.
That will serve the purpose until you find the original rubber which extremely scarce.
