you dont have rocker arms and push rods to wear on these bikes like a car or older bike has
and valve steams dont wear much on top because the bucket sits in a hole and goes stright up and down on the valve.

When dealing with described changes in sound, what we all are doing here is guessing. I hope you understand that, SCR.

And, from where I sit, a lot of things aren't making much sense. Valve clearance on these bikes does tend to tighten over time and I'm a bit surprised that the dealer found them too loose. Too loose is far better than too tight, and slightly out of spec loose isn't a big deal to me.

If it were me I'd get the dealer to specify what they did, shim by shim, on paper, so you have a record of where it was, where it is now., so you That way you will know what you have got in case there are more problems. If they charged you for shims then you should get the old ones back. They're yours, and they are overpriced, so keep them. If they just traded them out, that's fine.

As for the "settling in" comment, those are just words to get you to go away. The adjustment "settled them in," that was what it was for, if needed.

If they did anything close to right, you probably don't have a problem but I would still take it in and have them listen to it, tell you that it is OK, in front of witnesses, and then just quit worrying about it.

These bikes, when perfectly set up, sound like a bunch of ball bearings rattling in a can, and any change in sound can catch your ear, but that doesn't necessarily mean its bad. If they changed a few shims there will be a change in sound. What I don't get is how the ticking got louder when they "tightened" the clearances.

Anybody have a guess on that one?

The only thing I can think of is the oil viscosity. Was an oil change done on the bike? Did they use a thinner oil. It really shouldn't make much difference since the bikes have a mechanical valve train and will rattle anyway but it is the only thing I can think of. Tighter clearances should give less noise.

My bike will be fairly quiet just before I shut down after a run. If I park it for 20 minutes and start it up, the top end sounds noisy for a few minutes then quiets down (Maybe it's just me getting used to the noise). If I start it up in the morning, it sounds relatively quiet. I really don't get bent out of shape about it. Mechanical valve trains are noisy by nature.

One other item to consider is cam chain tension (too loose-I had this problem on my Yamaha). What if the cam gear tensioners weren't properly tensioned?

If the factory shipped my bike with the valves within spec, and if the service records from the previous owner were correct, the first time my valves were touched was when I shimmed them this past August. I'd put all but the first 4100 miles on the bike. When I checked the valves, the bike had approx 22,000 miles showing. All the valves were on the loose side of the spec. Here's what I found when I checked them:

EXH .33 .31 .31 .31
INT .25 .26 .25 .20

I did the 'math', pulled the cams, purchased shims, and reshimmed to bring the clearances within spec. In my case, the engine ran more quietly (makes sense) since the valve clearances were tighter after I brought them within spec.

I would have to say that mine loosened over 22,000 miles instead of tightening up.

Note - I did not run the bike to 22000 miles without checking the valves. They were checked shortly after I purchased the bike (used), and again at 12,000 miles.

My 2004 Bonnie has aprox. 9800 miles:

exhaust: .012" .011" .012" .012"

intake: .008" .008" .008" .008"

Triumph spec:

intake = .006" to .008"

exhaust = .010" to .012"

My gap now is at the sloppy side. Probably have to reshim at 12,000 miles.

Gregger makes a valid point about oil. I tried valvoline in mine at one point, but i believe it was dino oil. In any case, it quieted the bike down quite a bit, tho at the cost of performance. the response got pretty weak with the valvoline so i went back to mobil 1. So depending on what they put in it and what WAS in it, that could make a diff.

A mechanic at my dealer said that how you ride your bike effects how the valve clearances form. If you toodle around 4000 rpm the valves will tighten up and if you stretch her legs around 5-6000 rpm the valves will get looser. Mine have all loosened slightly as well at 32000 k's.

i don't ride her like i stole her but i do enjoy riding aggresively when it can be done safely... there are some wide open rodes in the middle of nowhere where i get my feet on the rear pegs, tuck in between the handlebars and get her up to a good sprint of about 107 mph from time to time so i guess it would make sense that they had to tighten them...

Normandy, the dealer is yanking your chain...

Wear causes the clearances to open up. If your bike was quieter before the service I would assume the dealer found the clearances too tight and made the necessary adjustments.

That's what I told him but he stood his ground. If wear causes the clearances to open up, how could the dealer find the clearance too tight ?
