Rear Wheel before and after!

I knew that I wanted a better wheel on the back of my 1980 CR 390 project. Aim was to find a 83 XC wheel and use it . Better Wheel. Better Hub. Better brakes...LOL! 18" over 17" running in the longer 1980 23 1/4" swingarm.

The Ebay search started. I actually bought three wheel sets before I found enough good usable parts to make what I wanted...

Here it goes from start to finish

Side views.. needs work..

Did someone take a side grinder to this wheel or what??? I have never seen a wheel marked up like this!

Nastiness:

Rust in hub after cleaning:

Now lets strip this thing and start making it look new again:

After Black coating and with new Motion Pro Rim locks (x2):

And a freshly turned Hub!!!

Look how smooth that wheel is now!

And now for Custom "Made Special For Me" Rim decals by Roost MX****************************************

And one last shot - Ready for new sprockets and Quality German bearings****************************************

Just wait until you see the brake backers for this wheelset.... this is really getting fun now!

FRAME /SWINGARM BARE METAL CLEAR COAT / Titanium effect

Third time is the charm!

I was not happy with the clear coat from before so I did it a third time.

Bead blasted to a somewhat rough finish and immediately clear coated with UV and chip resistant powder and have let it cure out for about 6 weeks.

There is absolutely no color on this frame. This is bare metal, media blasted for effect and cleared.

I wanted a titanium type look with the metal kind of appearing through it.

If you look at the swingarm pic that is up close you will see how the bare metal sparkles through... even though the clear coat makes the metal take on a darker Titanium color. Up close this is just amazing to see. Truly Unique...

Here are some pics:

There will be more up close shots in the threads ahead.

Swingarm Bearing Install Tool

I saw a picture of something similar to this on Yahoo Husky Group. Credit for the design goes to Peter ???

I tweaked it a little bit and made myself a homemade bearing installer.

Bearings will recess to exactly 3 mm for correct depth for O-ring insertion. OD of machined bushing keeps needles in place and tight during install. No hammers, no drifts, no swearing involved.

More swing arm pics in the next thread!

HT,
Love the "colorless" finish. That is one bada=s looking frame! Parts look great too. Reassembly on the horizon? Very very cool!

Sorry Schimm... just saw this... Closed out Disneyland at Midnight last night with the kids and their friends... my daughters 9th birthday****************************************! The Haunted Mansion set up as Tim Burton's "Nightmare before Christmas" was my personal favorite...

With a little luck but more importantly free time during the holidays, I should have a rolling frame complete by New Years.

Swingarm will hopefully get assembled today but have season ender Little League game( i'm a coach on my son's team) followed by an awards Pizza Party.

Then , per the recommendation of George @ Uptite, on to tackle the motor conversion from 1980 CR390 to CR420...making a great motor even better!
