If fitting a big bore kit you need to check the gudgeon pin diameter is the same on your saw, these can vary. I did a stihl recently and had to buy another piston, the original had a 9mm piston pin and the big bore kit came with what I think was a 10mm. Found a piston to match in the end but it wasn't straight forward. Just saying.
