      Thanks for your question! does not recommend ordering parts for a year or model other than that of your machine. Although the parts may appear similar, the manufacturer often makes changes in parts from year to year, model to model, which will create compatibility issues.

      Thanks for your question! With the Yamaha Banshee, in order to get the 66.25mm piston you would need the 1.25 oversized piston, unfortunately we do not carry a WSM kit with these specs but they are offered.
