Added a shim to the casting side of the slide bushing. Seems to work ok.
-
On the yoke...
-
Not sure what you mean by "removing slack". Are you having some kind of problem you are fixing?
-
up/down sidetoside?
-
Sorry, frount to back...cee baily ultra dome and 56k..The movement concerned me most in cross winds and traffic.
-
I've got the same issue, but haven't addressed it yet. A big windscreen on the highway will do it.

Warning:
I had slack on my '11 with a CB screen that I was not real concerned with.
Then I took the bike in for the 16K service and they found some rivets that had come loose on the mounting bracket. You might want to look real close or have the dealer take a look. I don't see any good outcome from that bracket coming loose at speed.
-
I just noticed this today on my new-to-me 09. Seems to be a bit loose front to rear. I don't notice it cruising down the freeway but only when there's no load on it and road bumps can move it a bit. Guess I need to investigate, are all C14s like this to some degree?
-
No. I have very little or no slack in mine. Could be manufacturing tolerances off, could be wear, could be riding fast with a large screen. Could be anything. It's not a bad idea, though, when you have it down for some maintenance to check that out. I do grease my slides with white lithium about once a year.
-
Yeah I've checked other ones and most don't have it. I rode my bike with a giant screen at high speed in heavy winds once. I had to hold onto the screen as I came around big trucks. The screen was going crazy. It put all that wear in there after a 250 mile ride. I haven't used that screen since.
-
I have a larger than stock screen. I think it's a Calsi, plus 6". I'm guessing the mechanism isn't made for handling the larger screens?
-
if physics are of any help, the area of the screen will have a linear relationship with the stress on the mechanism, whereas the speed will have to be squared.
Meaning: a screen of 20% more area will increase stress on the bracket by a factor of 1.2 (so 20% more forces) while riding at 120 mph instead of 100 mph will increase the stress by a factor of 1.44 (1.2², so 44% higher forces). This doesn't account for changes on the aerodynamic coefficients or the height of center of pressure.
Implications: for the ones driving at legal speeds or slightly above: you can basically mount a sale there and still exert far less forces there than somebody with a stock screen driving at 130 mph. But none of us would drive faster than the legal speed limit, now, would we? ;D

I've got a V-Stream (which is larger than stock) and have no problems at 120 with the screen all the way up. You've got to take the shape of the screen into consideration and not just the size.

Have you been talking to Brian, Martin?
-
Have about 50,000 miles with a CB Ultra Tour Domed. Haven't done anything to it. It moves some in turbulence but not too bad. Might be time to check and lube the mechanism. Thanks for the heads up.
-
I dove into the mechanism and checked things out. All looked good and the slight play is from the sliding mechanism. I greased things up and put it all back together.
-
Relief holes(vents) help a LOT and don't pass much weather at you. If the holes are down low, so even when the shield is up the holes are behind the dash, you will equalize the pressure and have a smoother ride and use less throttle to go the same speed.
Sorry - I just battled this issue as it looked like the mechanism was suffering and my windscreen was sure to crack eventually. I use a big V-Stream on a '10….and was also holding onto it passing trucks! Sucks!!
Thanks - hope this was of some help.
-
Enlarged vent in Cee Bailey.....Oh YEA

There are two mounting bolts to the rear of the windshield housing/dash that mount to the frame, in front of the stem bearing and just below the triple tree. You will have to remove a brake line bracket to tighten the nuts. Mine lost both nuts and the bolts were in the process of backing out of the mounting bracket. It can only be reached from under the dash. Once tightened your windshield play will be gone.
-
Is the play on the mechanism itself, or because all of you reporting that issue, have aftermarket screens, which are thinner than stock? Or maybe both? With aftermarket screens, you definitely need to shim appropriate brackets to remove extra play. Glad I read this to check all fasteners when installing the CooperDawg sport screen. Thx.
-
Not everyone gets this issue even with the larger screens..but it is good information to know.

I checked mine and they're tight. My small amount of play is in the track.
