Source for aftermarket swingarm chain guard?

[1911user]

The swingarm chain guard on my 90 kdx is worn into two pieces at the front of the swingarm. The Kawasaki part is $27 on ron ayers site. That seems kind of high for a rubber strip with 4 bolt holes.

Are there any aftermarket choices? Tips to repair the current one?

funny , I'm in the same situation currently. I need the chain guard and chain guide for my YZ.
cheapest I've found them for online is around $60 for OEM (pays for both parts) but I too am like what the @%#$ !!
its just a piece of plastic.

You mean that 'looks like a piece of black bungee cord', type of thing ?....

1191user,for the KDx you might want to try MSR and White Bros for the front chain slider(thing on the swingarm) and Fredette or White Bros for a chain guide(thing at the back sprocket) They all list them for this bike.Rocky Mountain and White Bros sites.$27 seems about right.
Speeed you have a wider selection to chose from UFO,White Bros. and T.M. designs.there could even be more, the yzs have alot more aftermaket stuff available for them, these are the only catalogs I have at home.
You can make your own chain guide blocks if you have access to a plastic shop just take the old block with you and they should be able to cut you a piece of teflon stock to match.I have even heard of a piece of hard wood being used as well,oak or black walnut,yes it does work. ;) Might also be able to make the swingarm chain slider out of a piece of flat stock if its cheap enough,Just heat it up and bend a piece around the front of swingarm and attach with the oem screws.

I dont think a tire would work, tho it would be nice if it did , but i do belive the guides are made of a nylon material , not plastic , so they will last more than 1 ride , and have a non-resistant surface to the chain.

I made mine also. The top is made from a white plastic called UHMW (Ultra High Molecular Weight) and the bottom is a black material called Delrin. I was curious which would last longer, but after almost a year they are about the same. Both materials can be purchased from McMaster Carr online for a very reasonable price. I can post a couple of pictures if anyone would like to see them.

Guys the simple and cheap solution is go to a shoe repair shop and buy a piece of new (or used) synthetic sole material (probably neoprene) of the correct thickness. Use the old one as a pattern and trim it out with sharp knives and wood sanding techniques. I put one on a previous KDX and it lasted for years and was still on it when I sold it. Cheers John

Chain Slider

I made one wonce out of a tire! Used the sidewall of an old bias ply cut to shape and wrapped around swingarm so it covered both top and bottom.Never replaced it! :ride:

I made one out of a timing belt. I made a couple of spares but have not had to replace the first one.
Question: Does anybody know how or where to get or make a lower chain guide?
Thanks for the help.

UMHW rules. We used to run chains over when I built food coveyors. Doesn't wear and super slippery. I used to make copers for my skateboards out of it. I would have to rough it up with a grinder to slow down the board.

Copers? Man, I hope you meant to say rails.
