Another 2004 KX125 rebuild? Yessir!

That's a pretty roached piston if I've ever seen one.









Notchless to say, that clutch is primo.

Whatever you do, do not put a 2018 front fender setup on. Modern fenders look like ass on the last gen two strokes.

Anodizing stock hubs will be very hard. It will turn out flat in color, unless you turn them on a lathe and polish them.

He meant Cerakote, he's just learning!

Whatever else you do, leave the swingarm silver.

Rookie mistake.

All good bro. If you’ve got any questions, I’ve built a few of those Kawi’s from the ground up.

Sending the frame and rims off to get a gloss black powder coat.

Cleaned the hubs up with a wire wheel on a bench grinder and used a dremel wire wheel in the tighter areas. They came out pretty sweet.

Exhaust pipe and silencer got the scotch brite and steel wool treatment.

Off to a good start!

2005 was not Chevy Trucks.

I want to mint this swing arm out but this is the first time I'm dealing with a painted swing arm. Do any of you have recommendations? Do I strip the paint with a paint stripper or just hit it with the scotch brite pads right away to remove the paint? My plan is to use 80 grit up to 220 once paint is stripped.

You want to use scotch brite to remove the pain then use sand paper?? Little bass ackward if you ask me...

Use the sand paper to remove the paint, work your way to higher and higher grit then repaint it.

I was just wondering if that's the most efficient way. I read a lot of guys have used aircraft paint remover or soft abrasive pads to knock the paint off. Was wondering if paint would fill the grit too quick and potentially take more time.

Drop it at a powder coater to have blasted and powdercoated, I think the common color used for swingarms is a BMW silver

There's a company called Protocol that makes a non chemical paint stripper, in Canada it's sold through Praxair but not sure about the US. I stripped my '03 KX swingarm and it worked exceptionally well without attacking the aluminum

I’d second the aircraft remover used it a bunch pretty effortless

Subframe is dialed.

First time throwing fasteners in a tumbler. They came out pretty decent. Anyone else use tumblers?

I'd like to know more about tumblers?

This is the tumbler used

This is the media and polish used

You can find the above items cheaper but my old man had cabela's points to use up so that is the reason for the cabela's plug.

This was my second experience with the tumbler, I did my personal hardware on my CR. I did not thoroughly clean the hardware, to be honest I just took the hardware off the bike and through it right into the tumbler with no polish. My results were okay after about 5 hours but the corn cob media stuck to the grease and didn't clean those areas well.
I purchased an ultrasonic cleaner for $120 on ebay and I am going to try putting all the hardware in the cleaner first then the tumbler. The results seen above were about 7 hours and 3-4 cap fulls of the polish. Only so long because I honestly had it running on the side of my house so I didn't have to listen to it and I forgot about it and left.

Thanks for the info mate. Don't want to hi-jack your thread mate but I have a 2000 model kx125 I'm building and I'm struggling to find any info on what pro circuit works pipes fit, do you have any answers?

Radiators are looking solid. Dremel abrasive wheels doing the trick.

They're actually a fun old bike, parts are dirt cheap and easy to obtain. I did one, went a little over the top, but, there you go. If you wanna different look, we can handle it, not too difficult, scrubdesignz.com...

Ended up going with the aircraft paint stripper on the swing arm. Then I proceeded to hit it with the 220-grid/scotch brite combo. Thing came out cleannnn.

Finally got my cylinder back from Millennium Technologies after getting it honed and replated. Dropped a new Wiseco piston kit in it as well. Top end is looking cherry.

Next steps will probably be cleaning the cases and starting to put this bad boy back together. Unfortunately now that classes have started back up I definitely won't be working on this puppy as much as I'd like too so have patience with me! Haha
