I haven't noticed that sound personally so this is just a guess. Someone mentioned on this forum that as the cam chain stretches the noise will increase until the tensioner takes it up another ratchet notch and then it will quiet back down and the cycle will slowly repeat. I don't know if this is what you are hearing or not.

 

damn, i guess ill just button it all back up, and keep riding.. if something breaks it breaks, then i will know what was making noise..... dont know what else to do.

 

If the bike is still under warranty and the noise continues I would probably run it by the dealer. I mean if your hearing it above the big gun exhaust that means its a pretty loud noise. thats probably not good. My 2 cents...

yea that kinda what i figured thats why i decided to check the valves.... so maybe ill have them look at it.

 

Also verify the header bolts are tight. After running in your Big Gun, they may have backed out a bit. The slightest leak there can sound like valve tick.

 

+1 Same thing with Yammi 4-stroke outboards.

 

My guess would be cam chain tensioner

 

exhaust is tight.... would the tensioner tick loud enough to hear over the big gun with quiet core out?

 

Never heard a big gun sorry

 

EMS, I just noticed a ticking sound yesterday. I have the Muzzy and I could hear it over the exhaust with helmet on. I don't hear it at idle, I mostly notice it when I'm decelerating. I'm going to try and locate the source of the noise tonight, and I'll let you know what I find.
