Ken,
don't listen to Carl.
Jet it as lean as you want, especially in 40 degree weather and skip that stinky oil. Custom welded pistons are the HOT setup!
Seriously, glad to see th TZ getting some TLC. Looking forward to seeing it in the spring.
This piston was the result of too little oil (spilled some in the wind mixing in the tank) and a little too lean at 1/4 throttle. Bigger main was not enough. It ran PERFECT, plug was nice and brown. Rolled off after a bonzi fireroad blast and she locked up tight.
