While I have this down time recovering from ACL replacement surgery, I have had a lot of time to work on the 98 YZ-400. I finally am getting to the chain and sprockets and noticed how beat up the aluminum chain guide is. Anyone tried the TM Designworks guide. I put the rub block on some time ago, and other than the noise, like it a lot. I just wonder how the nylon piece hanging down from the swing arm will hold up.

Other stuff swingarm/linkage bearings, greased steering stem bearings, forks serviced new seals, long sealsavers, hebo clutch, fastline brakeline with custom bracket, complete valve job, clean up ports in head, 426 con rod, 426 cylinder, 426 piston (weisco), WR transmission, new shift forks, BBR Kicker 1" shorter, rebuilt Scotts damper, SS brake pins.

Hmmmm, maybe I should have kept the 520 and just had the suspension done.... it would have been cheaper.

I’ve had two on two bikes, they are pretty indestructible. They may not give it in writing, but I was told they were guaranteed against breakage. As for wear, they do not appear to wear much at all, although after a while your chain lube will stain portions of the white guide. I probably have 100 hours on the older one and it looks good for that much more at least.

For both bikes I just bought the kit that included rollers, guard and guide. FYI the newer model arm guards have a preformed rail for the rollers to ride on, getting rid of probably 90% of the noise.

Hope this helps.

I have one of the newer rails with the pre formed ridge for the chain and it still made a ton of noise until I remounted it and put Automotive grade GOOP under it. Now it make almost no noise what-so-ever. Best advice Ive ever used. I dont remember who told me to goop it, but it worked great, I couldnt stand the noise. It sounded like firecrackers going off!

Sounds like the noise is between the guide and the swingarm, not the chain and guide.... interesting.

I have over 250 miles on my buffer, and guide.
I love them! they are holding up great!
my guide said 3 yr warranty on the package. (the part by the rear sprocket)

and my GOOP is starting to seperate from the buffer, but not from the swingarm. its getting a little noisier, but not bad at all. i will remove the old GOOP, clean and reapply!
It takes almost all the noise out of the chain slap! definatly worth the effort!

Automotive "GOOP" (glue) found everywhere, home depot, wally world, auto parts store. it's worth the 4$..... trust me :)
