I don't understand. Just what is that material?
And is the chain simply running along, wearing a groove in it?

its UMHW and its an ultra resistant friction proof plastic synthetic used in huge industrial machines. i used a band saw to cut out a groov and then run the chain through it. the jaged edges get worn down smooth and then there is no resistance on the chain. i have run 3000km through this thing and never had a problem. it also will not melt. its rough for the first few kms you run with it until its set then its smoother than a wheel!

UHMW = Ultra High Molecular Weight plastic. It is a form of plastic with a polymer chain weight in the 100's of thousands of Daltons, and is a self lubricating bearing surface used in chain conveyors and other applications where metal drags across it. It can be worked with ordinary woodworking tools - cut, lathed, etc to just about any shape you need. Most woodworking supply houses sell rolls of it in the form of tape, about 1/32 inch thivk and an inch wide - it makes great drawer slides, table slides, and guide faces for bandsaws. It is also availabe in just about any size/thickness sheet you might want.
Great stuff.

It also works great for custom intakes. It is fuel resistant and isolates the carburetor really well. You can find it on ebay.

That is really cool. I had never heard of this and in looking around for some to try, found it also comes in colors. http://www.garlandmfg.com/plastics/products.html

I've made a new chain tentioner out of an old Derailier gear cog sleeved it and it fits strait onto the stock plate. Works a treat, no chain noise and runs smooth as.

I had a Yamaha 500cc thumper
it used it on the chain tensioner
used when I bought it
used when I sold it
that plastic looking stuff holds up very well -- super smooth also
the chains glide over those things

Any chance you could provide pictures of your custom installation?
