My 89 BMW K100 RS100 has a two piece front fender. During a maintenance procedure I removed the front and rear fenders. No problems. The re-installment of the front piece is no problem but the rear piece is another matter. Seems the dual calipers inverted U shaped metal brake lines prevents the rear section fender from being placed back into position. Do not recall any problem during removal. Been messing with it for several weeks as I don't want to force anything into place. Any suggestions or prior experience would be appreciated. Thanks, Ken in Katy.
