Race for the Cure: S-Model Mirror and Fairing Buzz Thread

[scottymac]

Ok, it seems that we S owners have collectively accepted that for better or for worse, the mirrors and fairing are going to fuzz and vibrate. That's just how it is.

Or is it? Is there a fix to be had? I say we put our heads together and see if there is. How much more complete would your love for your bike be if we could come up with a how-to so current and potential Z750 owners could see this is something that can be eliminated.

(I hear the non-S owners laughing...  :wink:

So please, if you done any experimenting or have any insight, post here in this thread. Words of encouragement or outright mockery are always welcome. I'll be plugging along with it as time allows.

I'm still new to the z750s but I haven't seen to much of the buzzing could it be its only on the 05's? (mine is a 06)

[scottymac]

Hey John-

Mine's an '06 too.

It really is an only an issue from roughly 6-8K rpm. Otherwise it's as smooth as any other inline four I've owned.

I would not be surprised to find it's a lot different from bike to bike even within the same model year. Could be a couple of fasteners that aren't tightened properly, for all I know.

[johnd24]

Yea I see it now was trying to keep rpm's below 6000 but now I see it. Dosen't seem to be to bad just go quick those 6000 and its gone:)

while I'm still breakin in the engine, on the high way the other day the vibes in the mirror really wasn't so bad for the brief time I was in the higher range, (just could not help myself)  still can't see behind me without body contoursions though.  The bike really does pull though

I put some Salamander bar end weights on, and that's made a huge difference with the bar buzziness.

I still need to do something about the mirror vibration, too, so let's all keep each other posted with our tinkerings.

[Christopher]

I need to retract, my mirror statement.  The mirrors  do a fair share on "vibing" and there is a small amount of Buzz with the fairing and windscreen. But don't all fairing buzz?

Here might be a silly idea for the mirrors: At one point in car history windshield wipers had problems staying on the windshield. So they designed a small wing or airfoil that was placed on the top of the arm to provide a bit of down force and hold the wiper blade to the windshield.

In this fashion, what about a small clear or black plastic piece atop of the mirror, would this act as a stabilizer? This piece would be small no more than a half inch wide by one and a half inches long.

Any comments? (be nice. . . remember no idea is a bad idea, just one that doesn't work)

[JohnHS]

I plan on getting some heavy bar end weights to help the vibes in the bars but what about the foot pegs? seems like there should be a way to isolate them with a rubber bushing or something but I haven't seen anyone tackle that one. I know my feet can feel like I'm walking on wire springs for awhile after a nice long ride at around 85 mph.

I've heard of guys filling the handle bars with silicone? do know if its true or not....

Silicone and lead shot.  It's much easier to install heavy bar ends though.

[mgw750]

I put #8 shot in my bars, seems to work well.

Did a considerable amount of riding today and thought a lot about the fairing/mirror buzz.

Reach out and touch any part of the fairing while you're riding at most any cruise rpm, and especially within the 6-8K rpm "buzz zone".

The entire fairing- windscreen, areas by the mirror mounts, lower side sections by the tank all of it, it's absolutely spastic with vibration.

Gotta be the fairing stay mounting locations at the frame, and then the points where the plastic meets the fairing stay.

I'm pretty sure that unless you go strictly with bar-end mirrors, it won't matter what mirrors you run on the fairing....they will vibrate to some degree because the entire fairing as an assembly is humming along with the vibes. And the mirrors are rubber mounted on both sides, but it's ineffective because the mounting location itself is vibrating- there's no true isolation there.

I really want to put some time and experimentation into this.

I think we should start a research fund for scottymac, to look into this matter further.

Put me in for two chickens and a goat.

What happened at the dyno?

[scottymac]

LOL!

Working on a dyno post....didn't go quite as planned.

I have an old cat with digestive problems that I'd be happy to donate.

BTW, I had the fairing off this weekend to muck with my turn signals (for the &@^!# third time), and the main place where that front headlight/mirror/quarter fairing assembly connects to the frame has the same big rubber washer stuff as the mirror mount points.  There are three bolts on the frame that attach to the fairing just under/behind the instrument panel.  All the other connections are those stupid plastic rivets or the small hex bolts (like on the windscreen).

I didn't have time to find all the other places that the fairing connects to itself once off the bike though, since I had to reassemble for a ride that I'm currently running late for because I'm posting to the internet.    

Anyway, just FYI.
