Default Trying to Troubleshoot a clacking sound from front piston exhaust pipe

I have a 2006 Vages with 10,000 miles on it . And there was a very faint clacking sound coming from the front exhaust pipe when I bought the bike. But now that I have put 5000 more miles on the it , it seems a little louder to the point it bothers me .
And Iím trying to find out what is causing this sound . I check the oil psi , 80 psi , check the front cam spring adjuster ,it look good not frozen up. And I check for a loose baffle inside the front pipe. The sound itís not consistent like a valve tapping with the RPMs of the motor itís more of an inconsistent clack clack and then it stops for 2 or 3seconds and does it again . This sound also fades as the motor heats up .
Could this sound be piston slap ?

I did see that as the possible cause in the service manual. But there are no good pictures or info on how to replace them .

Oh, I read through this thread too fast. I thought you ruled that out. Yeah; sounds like a weak/bad lifter.

Both of mine will tap like crazy when they have sat for a couple weeks without starting. Goes away as soon as the oil pumps them up. My 2011 sat for a couple of months one time and it took a while for the tapping to go away. Probably 2 miles or so.

I thought that I ruled out the front hydraulic cam chain tensioner . But I have no way of testing it so if it’s cheap like under 50 bucks I might just buy one . The Hydro lifters are up by the valve springs . What the clacking sound is coming from exactly is a hard thing to determine . Which did you replace the hydraulic cam tensioner‘s or hydraulic lifters in the top in the motor ?

I doubt it's the cam tensioner. I guess it could be. Maybe a faulty part from the maker.

It's more likely to be one of the lifters. If it's a front one; it's easy to get at and pull the valve cover.

I didn't replace anything. They just pumped up and were fine.

I drained the 15/40 oil from it today and replace it with M1 20/50 . Then ran the bike twice about 3 hours apart for a good cool down . And will say there was no change .

This is the same exact sound but from a different bike , I just got this off of YouTube
Sounds like a loose baffle right .
