Odd? seems to go away with a blip of the throttle?

Re: Geoff's 3AJ rebuilds....
I think I'd be pulling covers and make sure nothing is loose. Sounds like something is rocking back and forth and blipping throttle causes it to stabilize momentarily. I had a loose flywheel on a two stroke Rz350 that got quiet at higher rpm, rattled badly at idle. Nut had backed off and was flywheel was chewing up the half moon key. I had to use valve grinding compound on the shaft and flywheel to smooth out the roughness, cleaned up and torqued new nut and key. Quiet as can be now.

Re: Geoff's 3AJ rebuilds....
Yes its the same with the clutch in Mez, first thing I'll check will be the primary gear nut.
The noise came on last Sunday, went out for a ride & I noticed it when I pulled in the garage for fuel. Definitely sounds like something come loose

Re: Geoff's 3AJ rebuilds....
Just to clarify, are we talking about the noise that has the same frequency as the exhaust note at tickover?
If it is that noise I think I'd have a look at the airbox/airbox lid.
Or is there another sound I'm missing
Bike looks BEAUT Geoff

Re: Geoff's 3AJ rebuilds....
You can hear it through the whole video, but it does sound worse as Mezo says at around 1:10 when the tick over slows down, sounds like a jackhammer Rick. I've already checked the flywheel Steve, I thought it was that too

Re: Geoff's 3AJ rebuilds....
It's been a long time since I listened to an air cooled & couldn't remember how much mechanical noise you NORMALY hear. Think I was listening to the inducion.
Try to isolate where the noise is coming from with a stethoscope or listen through the end of a long screwdriver Geoff, gives you a better idea of what to strip.

Re: Geoff's 3AJ rebuilds....
Been listening with a screwdriver Rick, hard to pin down though, can feel it through the screwdriver too
