I have a 1992 walker with the vtwin 16hp motor. Motor is bad. Everyone i talked to said that motor was junk in the first place. Im looking to put a 20hp or bigger Kohler motor in it. The estimates i have gotten from dealers around here are right at $3,000. Just wondering if anybody out there knows where i can get the engine and the kit (muffler, remote air filter) cheaper and do it my self.
