O.s speed ty tessman 110%
Is it possible to be running to lean and running under normal operating temp. I have it set up on a race tune and it was only running at 180°. I dont want to keep leaning it out to reach optimal temp and have something happen

Engine tuning is not really based on temps, more on sound and performance. Temps are more of a guide line.
If your engine is running on a "race tune" at 180° then let it be. Better life on the engine overall.

I am not an OS Engine person, but I assume this is it

That motor is a 21 XZ-B based
All I had to do was go to OS Engine website, find the engine, download the manual and the parts are right there!
