Death Rattle

It could well be an air lock in the lubrication system and the rattle is probably due to the hydraulic cam chain tensioner not being pressurised due to lack of oil pressure as the oil warning light is on. I would not run it with low oil pressure and the light on as it could damage the engine. The air lock needs to be sorted first and the light should go out within seconds of starting the engine.

 

Result. Glad you got it sorted

 

I'm curious, what bike this is on and what special oil change procedure is required to prevent an air lock in the lubrication system? I've never come across this on wet sump engines.

 

Strange but true. This is now Triumph's recommended method to prevent air locks. The oil level in the sump remains below the oil filter entry so oil will not piss out all over the floor. Still feels odd doing it this way though

 

I don't think Triumph have adopted the new method for an oil change across the range but there have been issues with late models of Speed Triple and this is their supposed fix for those bikes.
