Title: Exhaust manifold temps
Post by: DomP on October 26, 2025, 06:36:03 PM

Does anyone know what the exhaust temperature should be running at, as in what is a safe maximum?

I just did some tuning on my CB550K1.  Needle adjustment, re vacuum sync. Its running smoother than ever  all.plugs are a nice tan color. Checking the exhaust pipe right at the head the temps were 95ç -105ç after a 10 min ride.

That's roughly the same as im getting while im tweaking the carbs, so likely cooler once on the move I guess
