FITS ALL YAMAHA YFZ450 CARB MODELS AND YEARS. New after market 95mm cylinder. Wiseco CP or JE forged piston.

This is a bolt on kit that requires no machining of any kind. Our kits come standard with CP-Carrillo, JE, Wiseco, Wossner Pistons, Hotrods or Wiseco crankshafts, Hotcams or Webcams, Cometic, Vertex, Athena, or Winderosa gaskets and seals, and we have many of our own parts we have manufactured specifically for us. We always stock the exact same parts from different manufacturers so that when back orders occur like they have been for the last year we have an alternate part to send that is the same quality. This would be the ONLY reason your order might be slightly different when it arrives. All parts we sell have been tested and we have had huge success with them for the last 20 years.

If we ever have a part that does not function well it is immediately discontinued and we stand behind everything we sell 100% (unless otherwise stated in the listing). That way we can fix it for your ASAP. 99% of problems can be easily solved without returning the entire order. Once items have been installed or used in any way they are not eligible for return.

This product is NOT DIY. Over 99% of people in the world are not qualified to build an engine. It has to be done 100% correct, and many parts must be measured down to the.

The correct knowledge and tools are required to do this. We ALWAYS STRONGLY recommend parts be installed by a qualified, experienced mechanic. 99% of failures from kits that have pistons is because the ring gap was not properly set. It is the responsibility of the person assembling the parts to make sure this is done correctly. Also, we want information from customers when their experience is less than desirable so we know what areas need improvement the most.
