Triumph TR6 - Exhaust Rumble when De-accelarating

I am hearing a rumbling and minor backfiring thru the exhaust when I let off the gas and start to slow down. Espiceally when I am in 2nd or 3rd. Any ideas on what is cauing this? Thanks in advance.

Mine did that when I first got it. Carbs were set too lean.

If you're damper oil is low or leaking past the o-rings, it will also lean out the carbs and cause the popping. Piston rises too quickly, no resistence.

Exhaust leaks between the Cyl head and muffler can cause this on overun, I agree that the fuel mixture is the first thing to look at
