BigT- I know what your looking for. I would consider talking to the reputable Mod guys and get a new current mill. You always want a good "backup" engine on race day.
As far as the 09, it's really running rich at 185* How much fuel is through it? How'd you break it in? I have the R3 and the '10 RC engines and they usually run over 230* at race tune. Make sure you have a pipe recommended for your engine. Call Murnan, Rick Brake at RB Mods or Reno at RB USA, they'll help you out. Good Luck! Happy Holidays!
