Cam Chain noise?

Hi gang,
Would it seem unusual that my bike would be making some noise before it's warmed up with only 15,500 miles on it? Seems like it's getting a little noisier than before. Not just on cold mornings, but like this morning at 70+ degrees while warming up the bike, I hear it a little more than it seems like I have in the past.

Maybe the grambo or gambo trick is in order here??? I guess the ACCT springs could be wimping out already. I'd like your thoughts.

Fergy with only 15K on it, I would guess its just the springs sticking, go with your gut and do the gambo or grambo. or you can just swap them out all together and go with the manual cam chain tensioners.

I chatted with Dianna earlier and she said to do the grambo and if anything changes, I'll know it's my cam chain making noise. I plan to go ahead and order the apes. (after I do the grambo)

mine is doing the same.... as its warming up, it makes a rattling noise as if one of the heat shields are loose... and once its warm, its making a weird grinding ticking noise..... no metal in the oil. so i am guessing mine is the chain.... gonna get apes here soon cause the grambo trick worked for like the first 5 mins (my try to up the spring preload first), then noise came back. i have 11k miles. question though.... how tight should i do the grambo trick, just let the spring do it? or should i turn past where the spring stops tightining. also how tight should i get the apes?

What I've been reading today is that you turn the slotted bolt CW and let it spring back, then gently turn it CCW and see if it goes any farther.

The apes from what I've read, you adjust in until you feel the cam chain thingie, then start it up and adjust them in slightly until the noise goes away, then back out 1/4 turn and lock them. Then rev the bike and adjust them again the same way... That's what I remember from reading everything I could find on it today.

I think that all the grambo trick does is pop loose a stuck spring. Turning it the direction with resistance pushes the plunger in more, and removes the slack in the chain. This is a way of manually adjusting the tensioner. Unfortunately, you have to use a small screwdriver to do it, so you don't quite get the effect of using a wrench on the manual tensioners. Oh, and the automatic tensioners will actually loosen because the spring isn't strong enough to prevent the plunger from backing out.

Because they'll go out sooner than the originals. The way it works is that the spring unwinds, and when it reaches a certain amount of unwind, it no longer has any strength to keep the plunger tight. So by putting a new ACCT in, the only thing you have gained is a little stronger spring. The spring doesn't start back at the beginning; it starts where the old one left off.

on mine with the rigged up ACCT's that I had...remember there was a bolt screwed into them (not gypsy's mod) I turned the bolt in and believe me YOU WILL KNOW if you have them too tight....the noise that will come from those chains is very distinctive a whining rubbing noise.
