I don't know where you might get a trim strip, but you can replace the little screws. You'll have to first get the old ones out, the take some small screws, and slip the heads into the strip from one end. You might have to file them a little to fit into the strip. It's a pain in the ass, but it can be done.

Paint for frame components
Hey all
Just wondering if you can recommend a hardy (black) paint for use on the swingarm, stand etc?
Ive used what seemed to be a fairly tough paint but it chips like a drag queens nails...
Any thoughts?
(Cant get the swingarm powdercoated due to not wanting to remove bushes)
Cheers
Ash

Preparation is key as well as product selection for chip resistance.
Your choice of products is critical for chip resistance because the system has to work together to provide the necessary durability. If a lacquer primer is used under a Polyurethane topcoat, you will not get the durability expected from the Polyurethane. The primer in this case is the weak link.
Lacquer is a weak product. It has no catalyst and can be moved with solvent. The Polyurethane is catalyzed and cannot be moved once it has cured. This difference in technology causes the bond between the products to be weak and provide very little resistance to chipping.
A degreasing solvent to remove all the grease and oil prior to sanding/blasting etc. is a must. If this step is not done, the abrading will drive the contaminate into the surface of the metal and create a weak area.
An Epoxy primer such as PPG's Delfleet Evolution F3950 would be best. It will provide the necessary corrosion protection and excellent adhesion. There are other products out there that would be good for this situation. The key is to use a two part epoxy primer.
For the topcoat, the best product is a two part Polyurethane such as PPG's FDG or FDGH. This will provide the needed chemical resistance as well as impact resistance and a great shine.

I know this is an old post but I wanted to share what I discovered in case someone else has this issue. I also tried to find some gt500 fork dust seals and failed. The 1976 gt750k and l models use a rubber gaiter that should work but I was not sure how the top part would attach to the fork. The dust seals for a 1976 gt750m are still available from the dealership and will work with a little modification. The groove on the top of the lower fork leg is too low for the new seal to snap over so I had to widen the top edge of the groove about 1/8â€

dust covers
Thanks for the comment. I dont want to grind on my lowers to get other dust seals to fit. I have thought about Gaters like Lane suggests but he also suggested checking the newer bikes for covers that might, maybe, could, possibly fit. In time I will get out and do that. I'll pass along anything I find. Dofin

ZINC PLATING - "At Home Style..."
Also posted on the KTW board...
Ya'll...
I have been toying with the zinc plating idea since I have several project bikes in the mill that will need many parts plated. I know you can take a bucket of bolts down and have them plated for $30 or 40...but...I won't have everything together at once...and...I am apt to forget that one part I need to put something together. I know no one else has this problem... Right????
I've talked this chemical formula over with Lane and purchased them from an eBay seller for about $15 along with a LARGE surplus zinc anode for about the same price. I went and picked up some Muriatic Acid at Home Depot today for use as a "pickle" and decided to get started. Besides, my wife wasn't back with the wax I needed to get started on the rubber molding...
Thought I would post this as it seems really easy as long as you observe safety...goggles and gloves...
Here is the HIGH-TECH plating vat... Zinc anode bolted to one end with a long impact chisel across it to hang things from. M/C battery and a bulb to limit current to about 100ma per square inch of surface to be plated. I need to find a large wirewound rheostat (like I threw away a couple years back).

You also need to pickle the parts in the acid for a few minutes and then rinse WITHOUT touching them. I just attached a piece of thin copper wire to the parts and used that to handle them throughout the entire process...

First thing I tried was a small nut that stayed in the plating solution for about 25 minutes. After polishing up with a Scotchbrite pad it looked like this...

At this point I was pretty jazzed....so I looked around for more stuff to play with... How about rear wheel spacer and a passenger footpeg mount?
Here is the peg mount BEFORE...

Here is the spacer after the pickle and rinse...

The spacer partially plated and the peg mount going in the tank...

The spacer AFTER...

The peg mount AFTER...

This spring was REALLY NASTY... Corrosion, gunk, you-name-it...

I even found this old exhaust stud at the bottom of a parts bin with the rounded off nut still frozen on the stud...

It wound up looking better... (Yeah...I know it's unusable...)

Finally, here is a shot inside the tank where the "magic" is happening...

Just wanted to post this so if you've wanted to do some zinc plating but (like I did for years) thought it would be too complex or a pain...it doesn't seem like it is.
I also have a formula for the "Yellow Chromate" for ignition boxes and other parts. I need to get back in touch with my supplier and have her ship me some chromic acid... I'll update this thread later with the results...
Thanks for looking!!!!
