Perty clean lookin' bike!

I remember reading somewhere about using powered oxalic acid (wood bleach) to clean rusty chrome.  Just put some into water, soak the offending rusty parts for a few hours then go over them with a white scotch-brite pad and toothbrush.

Hell, its already been explained in detail here>> http://www.vintagebmx.com/community/index.php?showtopic=4004702  No need for me to retype everything

As far as rust removal goes, I've used this on my 77 f gas tank and its great http://www.safestrustremover.com/ . My concern is getting the finish (the stock look) right.

Thanks for all the feed back.

droool...wanna trade sidecovers?lol. Very nice looking bike, that aluminum looks as though it`ll clean up nicely with a little (ok alot) of elbow grease. Best of luck with it!

I polished all the alum and chrome using BLUE MAGIC and a small buffing wheel that I put on my 1/4 angle air grinder with a 1/4" arbor. Looks better than new....     I left the painted portions of the engine alone.

WOW - thanks for the pics - I was wondering how my 77 and 78 would look with polished front forks.  I am so in.   Very nice!

Well the clear on the Aluminum is coming off so just polish away..



If you want you bike to look cleaner, try this, put 72 headlite ears on it, and change sidecover emblems to 72 style......JMO.. but hey, I dont subscribe to "Stock Life"... ..

The 72 style is probably the best out of all the years.

My thoughts, exactly... 

Hey, Heff: what is "never dull"? I've always used Simichrome, and lately, also Mother's. Mother's is more work, but gives a real pretty sheen, a little diferent from Simichrome.

Nevrdull is awesome. It`s now distibuted by Eagle one

i learned about nevr- dull for my trumpets when i was a band geek in grade/high school.  go ahead... i've heard them all!   

when i really learned its worth was the time i decided that cleaning up some old Cragar wheels on my firebird might be fun.  i started w/ LIGHT steel wool for the surface rust and then used the nevr-dull wadding polish (its kindof weird like insulation soaked in silver polish that has dried back to the feel of insulation)... works like a charm.

i like the stuff because of it being wadding instead of a gel or fluid or paste... you just grab a wad, use it, realize its not too bad and stuff it back in the can for next time.

OK so here are some pics. I would really like to do a very meticulous correct-as-possible restoration.

Man, that is one gorgeous K3! 
I can't believe the finish on that tank paint!
That crashbar takes me back: had to give mine up when Vetter came out with lowers, went to just case guards instead. And used them, too often...   Your crash bar will do a better job, and brings that retro right home!

As far as the "original" look goes: the rear tire appears to be the wrong size, although it also appears to be a safer profile type than the original K87 rear type (looks like 120x90 metric, maybe?). The front was originally a ribbed pattern, which Avon makes in the original 3.25x19 size, in much better rubber (I have one on the front of mine now, OK until the pegs start to scrape, then drifts a bit, at 36-38 PSI). The ribbed ones tend to be more stable at speed than the "non-linear" variety, and Avon rubber is second to none for grip in all weather.

Nice work!

Thanks, still deciding weather to polish up the motor and hubs or let them be.
