Added reply in a thread Stripping YZ250 clutch cover to bare magnesium 10/9/2019 7:34 PM

I was hoping to not have to abrade the cover if possible. I know how good aluminium comes up with sodium hydroxide, was hoping to do the same!

Gday from Australia! My YZ250 clutch cover looks cruddy. I’d like to strip it back to bare magnesium. It looks anodised to me instead of painted, but I am unsure. I’ve used sodium hydroxide to remove anodising from aluminium parts, but haven’t tried ... more »

I've actually got a homemade carbon pipe hanger on my bike now, I'll have to take a pic this weekend and post it! Turned out pretty ace. The carbon pipe hanger has actually been fitted to my last three YZs, still rocking.

Dude, of course I know what the upper engine mounts do. It was a tongue-in-cheek comment. Relax. The alternating weave pattern in the layers gives it plenty of bracing. As mentioned, I had a set in my old bike for two years of hard abuse, not a problem. ... more »

Haha cheers for that man, all sorted now! Yeah I'm pretty stoked on how these ones turned out. I made a set for my YZ125 a while ago, they were offset so it was it was a fair bit more effort.

G'day! I made a set of these for my last YZ, had them in the bike for two years and never encountered any issues (honestly, I could probably run no upper engine mounts and it wouldn't even matter). Thought I'd show some pics. First I wet-laid some carbon

This is the fifth frame/swingarm combo I've had done, it holds up extremely well. I ride extreme enduro on my YZ250 two-stroke, and it holds up great. As you said though, looks are subjective.

Couple of inserts on the main frame that couldn't be removed, everything else we just unbolted. Everything on the swingarm was removable. We also anodized the engine mounts and chain adjuster blocks at the same time. I'll post pics of these, they look ... more »

Nope! The anodizing process involves being completely submerged I sodium hydroxide, which cleans away any junk. When we anodized the frame and swingarm of my YZ125 a while ago, I sanded back a few of the deeper gouges. This 250F frame was a lot less ... more »

Just a dollop of silicone over the steel nutserts. The sodium hydroxide doesn't affect the silicone, pretty handy!

Anodized. Completely different to painting, and much more neat and durable. Doesn't add any thickness to the material. Also gives a unique effect when two different styles of aluminum are anodized. You can see the cast parts are gray, yet the extruded ... more »

G'day from Australia! We just anodized my mate's frame, subframe and swingarm for his freshly rebuilt 2016 YZ250F. Turned out sweet! Go to Deadwood Moto black frame for Ackie Rush to see more.

We will have it assembled probably tomorrow, ... more »
