YS 45fs Side Exuast Rebuilt Engine
This engine was used when I purchased it. I contacted a dealer in California and ordered a piston and sleeve kit, front and rear bearings, check valve, drive washer and a full set of gaskets and orings. I ran it on a test stand after completing the rebuild. It ran great! I was going to put this on a Sig Kougar MK II from the kit I was building but, due to my first kid and a new job, my life took a different direction. I am including a YS factory muffler for use with this engine or you can get a header and tuned pipe for it.
