Clattering top end

[don]

Don't know if any of you have read any of my other posts, but now that it's running I'm getting a little more attentive to other things with my bike. As in my signature, I have an 83 gs 550e. It FINALLY runs great. I've purposly tuned her a tad rich with the plugs being slightly grey in stead of the bone white I'm uset to seeing with the race engines.

My question is this. Do these motors' top ends, (valves), usually get a bit chattery after a long ride or a nice highway ride? Mine do. I baught the adjusting tool and know for sure all of the valves are .004"-.0045". It's nice and quiet when it's cold but gets ... like I said...... chattery.

On the 16V 1100 it can be a little clackity at idle when hot but quickly disappears on any revs

A noisy valve train is a happy valve train. When they get real quiet(tight) thats when you have problems.

Thanks for the replies pos and al. Comments for both of you in response to you help. Pos, when it gets noisy, and I'm under way, the valves are almost louder than the stock pipes. It's like a swooishing noise. From what you are saying, I guess the answer to my question is yes, these motors get louder with a true heat-up. And al, being an old car engine guy, it makes sense to me that the noise is a good thing. No pushrods to poke holes in rockers and valve covers, lol.

Thanks for the help guys. I'm not gonna wory about it getting more clattery with heat.

Start it.......ride it........flog it............:twistedevil:

It should have a sewing machine type sound. If you've got loose nuts, bolts or shims flying around in the head, thats not a good sound.

A loose cam chain can make some very loud noises, is your cam chain tensioner working correctly?

I bought a Kawasaki Concours for a song once because the guy new it needed a new engine. "That thing is toast," he says,"Just listen to it" Rattly clanky banging clackety loud POS.

So forty bucks for a tensioner and I down the road in silence.

So it's worth a look.

It sounds like more noise than normal; I would pull the valve cover adjust the valves and make sure the chain is tensioned properly.

Anything above 2K rpm there should be no noise; with stock exhaust like al says like a sewing machine.

When I first got my bike I had it apart every other month thinking something was coming apart in the head. Never was. They are designed to sound like a shaking silverware drawer.

Of course on occasion your sounds worse than most

Yeah, clanging along with disco fog.

Bill..i did a search but to no avail..someone once upon a time had posted pics and a tutorial about making inserts for the ends of the cams to take up the slop..you know where we may find that??

Those are for the eight valve motors. I have sixteen valves with rockers.

yup both of my 750s are 8 valve..both have the clatter..it wont hurt anything as is, but someday i may just get the urge to dig into it..am makeing myself a performance and parrts vendor file in my documents and was wanting the info to squirrel away there. you know.. the materials he used and how he milled the inserts and such.

Took the valve cover off Saturday to run the feeler through the valves. There were a couple that were loose. Readjusted all of them and took it out today, (Sunday), for a quick 50-60 mile ride that included a couple of short highway stints. All seems well with the stealth bomber.

(One of my neighbors gave my bike that name because when I go by their house, (slow, 30-40 mph), the chain is the loudest thing on the bike.)

Once again thanks to all of you for the help.

That's where that darn 9mm socket went....

Thankfully not the case JW. The last time I adjusted them, I'm sure I cheated on more than one. In stead of actually readjusting a tight valve I just cracked the jam nut back a smidge, wondering of coarse if it would start to back off more over time........ quandry solved. Yes it will. And once again shortcuts are proven to be the long way. The sad part is I know better. Gettin lazy in my old age.

Sounds like you need a new chain and sprockets.
