Forgot the mention that the stock 372 piston is 97 grams with no pin, clips, or rings. The OEM 268 piston is 73 grams and the farmertec is 66 grams. The lighter piston makes a huge difference in the way it revs and throttle response.
Little disclaimer though, like many AM pistons the 268 piston from farmertec is to wide between the wrist pin journals and allows for some rod walk but minimal. Golf full circle 266 piston is worse sadly. So use AM pistons at your own risk. I'm not gonna tell you to use a farmertec and have it grenade only to catch hell from you guys. Just remember, YOU will determine the quality of your build even if it's as simple as cutting a piston to fit. The OEM 268 piston fits the rod like the OEM 372 piston.
The farmertec ones i built are not seeing production but they are being tested by firewood hacks in the area to see if they hold up. Farmertec ring and wrist pin as well as it's a good bit shorter then the 372 pin. OEM clips and pin bearing. I do have one i've been cutting with on the hill but i built it with an OEM 268 piston. With this new lumber tax i have a feeling it may be shelved for a while
