Ticking Noice still there

[templar]

I have now changed the pushrods, rebuilt the throttlebodys, changed the left camchaintensioner, changed the frontcamchain and rails and tensioner.done a valveadjust and a rockerarmadjustement.
Changed the adjustscrews for the valveadjustements
The tickingnoiceis still there and is more on the left than on the right side , and gets louder when the engine is warm .
The Noice frequence runs with the rpm.
What more can I doWhat is the cause of this?
Irun it on 20w50 ,
The bike is a2004 gsa

Has the left side cam chain tensioner been upgraded?

Yes

Pushrods?

 

[Pete.]

Throttle body shaft bushes worn? They tick very loudly when they are worn out. You can fix them quite easily with polymer bushes.

I believe there is an upgrade to the old pushrods. Read it somewhere in the past.

Have change them to the solid ones

Pushrods from the 1200 are solid and fit. I changed mine about £15 each from motorworks second hand if I remember correctly.

If its any consolation my old 80,000 mile 2002 R1150GS has always ticked on the left hand cylinder between being cold and fully warming up. I like you tried all sorts of things to eliminate it.......unsucessfully. Its very quiet when its warm mind. I did have to do a throttle body re-bush using a dan catta kit mind at about 67,000 miles the right one was making the loudest noise.

Have you tried a stethoscope, or listen with your ear to a large screwdriver handle, to tie down the source.

Seems you have addressed all the usual culprits, which leads me towards wondering if it could be piston slap or the small end bearings?

A blowing exhaust port gasket will often sound just like a mechanical tick.

Wha are you folks calling pushrods?

 

[Keith Chapman]

Might sound daft but could it be an injector firing that you can hear?

 

[Mzokk]

The little push rods on the 1150's they are about 50-75mm long for operating the rockers. In the 1150's they are three piece with steel ball ends and an alloy shaft. They are pushed together and over time the little ball ends can become loose and cause a ticking noise. The early 1200 ones are the same size but made of one piece of steel and don't therefore come apart.......thats the theory

Thanks @Mzokk
I always, wrongly, assumed the cam pushed directly on the rocker arms which in turn rocked and opened the valves.
I never knew, until now, the 1100/1150 & 1200's had pushrods

I have never thought about the injectors.
Do they get louder when worne?

I will investigate this . Seems like a not so expensive fix

I have tried to listen with a stetoscope, but it's hard to hear anything specific.
I have thought about both the small and big ends. And I've heard about someone who had a axial crankplay .
