Exup valve. What noise does a loose one make?
#4
It's like something loose with a tinkling sound at 30 to 40 on/off throttle. Normally if really loose it rattles like someone tapping a spanner on the exhaust at tickover when cold.”

That’s exactly what mine sounds like, rattling at tick over. Bizarrely, it didn’t do it before I had it refurbed. Did nothing to the EXUP so don’t understand what has changed. Anything that you can do about it??

I’ve serviced it regularly and had it apart again as soon as I noticed it rattling. But all the constituent parts were present and correct.

Sorry for the thread hijack.
