I think this has been discussed before however I can't find a suitable resolution as yet, the dreaded windscreen drive gear failure, mine finally gave up the ghost at 116k's, after a few hours work I found my gear like all others that havre failed has the stripped/worn teeth. I am now investigating the possibility of have a new one made using 3D printing, if I am successful I will get a few made for any other poor unfortunates whose bikes has have suffer a similar fate, if however someone has managed to get replacement gears made please let me know where I can get one.
Cheers

They are available from Bikequip in the UK, not cheap though... :thumbs

#edit: I just looked up the cost and currently it's roughly $321 AUD including shipping. |-i
That does includes replacement cables as well as the actual gear though...

I bit the bullet and ordered a repair from the UK, while it is a simple matter to get the gear made, the problem is the weird spiral cables which also need replacing, so I would advise people to do a bit of servicing on their screens

The RHS weird spiral cable on my original ST1300 popped out of its track and jammed. It's back in for now, but some more serious attention will be needed for it to work properly, that'll be a day or two job for me. In the meantime, I don't raise or lower the screen.

Try not to raise/lower the screen at speed it puts a lot more load on the gear.
-
Having an aftermarket larger screen will put additional strain on the gear as well...
I just leave my screen in the one position unless I really need to alter the height.
Like Glen said, try to only alter the height while travelling at slow speed so there's less stress on the mechanism.
>while it is a simple matter to get the gear made<
Apparently it's not as simple as you'd think, or at least that's what Steve from Bikequip has said...
It is worth mentioning at this point that manufacturing the gear involves a process called Electrical Discharge Machining (EDM) or more commonly known as ‘spark-erosion’ whereby a very fine wire is used to erode an intricate patterned recess in the base of the gear to provide a perfect fit onto the drive shaft of the wiper motor.
No other process can achieve this fine machining.

I have a windscreen metal gear in a box somewhere
I will have to find it and put it up for sale
I purchased it from the US and never used it
Stay tuned

I think the main cause of the failure is the lubricant in the cable, when I dismantled mine I thought the issue was the blocks not sliding freely however it turned out the the inner cable was the issue, I could barely move the cable.
