Clock lens remove/replace

1994 R100RT.... I need to remove and replace the clock lens. It has a large blister on it and I can hardly read the clock.
 
Removing the clock will be some fun...you'll need to read into the fairing from the sides to undo the knurled nut and relax the tension on the bracket holding the clock in place:

I suspect the lens will be firmly fixed to the body of the clock by a crimped ring around the edge. It takes some skill and maybe some tools to uncrimp and recrimp the ring so it still looks OK and is water tight. There are various places that can do this work...see the speedometer section in the link in my signature line. An alternative might be to buy a replacement from various sources...I bought a replacement voltmeter for my fairing from Bass Pro...they had good instruments designed to withstand the vibration and wet environment of boats.

Thank you for your reply. It sound like it is better to replace it. I do not have the tools for this job. I’ll heading to the internet to find the replacement.

It's actually not that hard. The trick is to get a flat blade screwdriver of the correct size that allows you to "unfold" the crimp to remove the lens and cover. Reassembly is the reverse.

Really.. I’ll try this and let you the outcome. Thanks for the input. Any suggestions on removing the faring?
 
Do you have to remove the fairing? Aren't there some pockets on the sides of the fairing that would allow you to reach around and remove the attachments? You might have to use a mirror and a flashlight to get a sense of things, but it should be possible to do all this "blind". The knurled nut and bracket hold the clock in place. There would then be a power and ground wire...maybe a wire for lighting...they hopefully these would just pull off.
 
No need to remove the fairing to get to the clock. Find the knurled nuts with an inspection mirror, and then reach up behind the dash panel to remove the wires and get to the nuts that hold the gauge's bracket on. Smaller hands are useful here.
 
A tight fit

Getting to the clock's knurled nuts is a very tight fit but can be done without taking the fairing off. A small hand works best. LOL. St.

I am going to put new fork springs in and need to take off the speedo for repairs. I am also replacing the headlight and the interment wire harness. So I figured it would be easier to remove the faring. I’m also replacing the windshield.
 
Steering stem grease

While you are in there....With the fairing off, this would be the perfect time to do this oft-ignored maintenance. Unless you know otherwise, assume that it has never been done. This is especially true on a full-fairing bike such as an RT or RS. The original grease turns to a stiff waxy substance over 35 years. With luck the bearings and cones just need cleaning and not replacement.

Thanks for the heads up.
 
Steering stem lock

At the risk of playing pile-on, also consider removing the lock assembly for cleaning in solvent and lubing with graphite for the same reason. It is a 15 minute job and will make it work like new.
