Notes: This kit is a real diamond in the rough. The first time we hit the track with this kit it really got our attention. It revs out super fast and pulls like a much bigger engine than what it is. It uses a +3mm Hot Rods crankshaft and a Max Power Ceramic Nickel Bore plated OEM 97mm cylinder. We also provide a full bottom end gasket and seal kit. It is basically a total rebuild kit less main bearings (and we can get you those also for a bit more) It comes in multiple compression ratios and uses either a CP or Wiesco piston – Your choice. If you got a tired YFZ, limited funds, and some mechnical skill, this kit is a pretty sweet deal that really does the trick.
