Hi Triumph friends!
A new noise recently appeared in the wide spectrum of sounds from my Rocket 2013 Roadster engine.
Here’s the video where you can hear it between seconds 2 and 6. After second 6, I roll on the throttle and it disappears.
There was always a lot of whining and other normal noises, but as I passed 20000 miles, this new highest pitch started to come and go. It is like crickets. I read, there is a thing called chirping and it happens with bike gets modified with Ramair filters, but mine is completely stock.
It started on a long range cruse at 70 mph. Mostly between 2000 and 2700, sometimes at or close to idle. While on cruise at 70 mph, it can be lasting for dozens of minutes and then disappear for a while, but it comes back again. I can hear it even when the bike is in neutral when revving in said range.
The frequency of this noise doesn’t change with RPM.
No degradation of performance was observed.
What preventative maintenance should I try to look into?
Thank you
