Screen adjustment behaving weirdly

[Oodoom]

Hello all, my screen has started misbehaving, was hoping to get some ideas on what the issue is.

Was working perfectly last time I rode the bike before Christmas, about 6 weeks ago I replaced the OEM screen with a VStream that is no taller and only a little wider. At the time I fitted it, I started the bike up and the screen adjustment seemed fine.

Got her out of hibernation this afternoon, fired her up and the screen didn't move and wasnt responding to the switch. After some experimentation, I established that if I repeatedly dab the button quickly, I can get it to go up and down, very slowly, in very small increments. If I hold the button down as normal, it either doesnt move at all, or it moves a little bit but then reverses and ends up back where it started. This happens going up or down.

I can get the screen all the way up with multiple dabs of the button. When I switch the ignition off, the screen behaves exactly as it normally does - ie. lowers automatically with smooth movement all the way down. When I fire her up again, the screen doesnt move and doesnt revert to where it was last set.

Anyone got any ideas? My initial thought was that the motors might be worn or jammed, but it automatically lowers itself like it has always done. Could it be a dodgy switch? Is there a control unit that might be faulty? TIA Trophy Hivemind!

The first thing you should do is remove the screen and check that the four pivots that hold the screen do their job correctly, both going up and down.

It could be that one of the four pivots that hold the screen is forced and that is what prevents the screen from going up and down correctly.

You must also check that the plastic stops are all and installed correctly, of course you must add some grease inside.

Once the screen is extracted, check the four pivots from left to right that any of them have no play, since they are aluminum pieces, some of them could have been damaged.

Once all this has been verified, if you still have problems, come back here and tell us about your experience.

With the dealer tool, you have an option to have it calibrate itself. I don't know if the DealerTool has that function.

My V-Stream moves very slowly as well, and when I installed it, I noticed that it does not fit the arms as flush as an OEM would.  I'm about to go back to an OEM screen and be done with aftermarket, since the shape is not the same as the OEM where it fastens to the arms.  I've also had a Cal Sci on it that I really liked for it's performance, but it fit the same as the V-Stream and functioned like the V-Stream as well.  I'm hoping that all this time with the aftermarkets haven't warped the operating mechanism any.  I still have my as new original screen but it's the low version and I would prefer the high touring one.

 Hi all i had meet this  little  issue with my screen
 i noticed that appears after i drived   with the full up position so
 after a cup of days , with engine start on and  neutral gear
 pushing the button , the screen goes up an down slowly
 also it moves a little bit but then reverses and ends up back also  where it started
 this phenomena disapears after 1 mn in traffic

Mine just started doing that also. I think, without any testing or measurements, that it is an indication of a weak or low battery. IDK.
But, I am also interested  in anyone's experience/knowledge in this anomaly.

A weak battery is certainly a possibility to explain why this happens,
and why it seems to resolve itself after the Bike has been running for a while,
when the Battery would get charged back up - so check / test the Battery condition,
and that all its contacts are clean and tight, together with checking for corrosion
inside the Main Fuse holder next to the Battery.

It is also worth cleaning the pivot points of the Screen arms to ensure they are free to move.
If they are tight this will place extra strain on the screen motor and could cause the "Anti-Trap"
feature ( where the screen reverses direction as described ) to engage.

Be careful not to drop and lose the little specialised retaining clips that hold the screen arm pivot pins in place !

A worse scenario is that there are some crimped wiring connections buried inside the main wiring harness
underneath the rear of the fuel tank, where the harness runs across from the two screen Relays on the
right side of the bike to the left side.  I know of one Member that had these connections corrode and fail !

If everything else checks out OK, get an auto electrician to test the wiring with a Test Meter to see if there are any signs
of increased Resistance in those wires - which might indicate the crimp connections starting to corrode or fail.

Hi
You mean the 30 amp fuse on battery from
Main wire could be guilty even if
It appears unburned?

I said to check all the Main Battery contacts are clean & tight and to also check the Main Fuseholder for corrosion.

Any loose connections or corroded terminals can result in reduced voltage.
