Broke the frame down today and removed all of the little parts and brackets from it.  When I went to loosen the nuts from the top triple I noticed a major problem on the right side.  It was cracked and when I removed the bolt holding it, it fell apart in two pieces.  So now I am in the hunt for another triple.

Harsh,
I'm leaving tomorrow morning to go be a very small vendor @ a small vintage Japanese swap meet and I'll be there until Sun.   Do you want me to find one there for you? if so PM me and you can phone me and I'll find you one there.I went there 3 years ago and a guy I met who came in as a buyer knew I was looking for one so he went back home and got me one for a good deal.  ;)

Met with Cal today.  He snagged my replacement head and is going to bead blast it then have his machinist do what needs to be done.  He also picked up a bunch of parts that attach to the frame that he is going to bead blast for me.

Since I can't do any engine work until I get the head back I figured I would get to work on the frame.  So I stripped it down to bare metal.  It was a bit of a pain because of little nooks and crannies, but I got it done.  There was a bunch of mouse fluff stuff on the inside of the frame, but I got it all out.

It was a bit of highs and lows over the past couple of days.  I cleaned up the frame a little bit (well a lot) more.  I took a wire wheel to it and removed any imperfections and gave it a bit of a tooth for the powder coat to grab a hold to.  Also spent some time sanding the rear brake plate and then I polished it up nice and shiny today.  Took the rear tire off the wheel and at some point instead of using a rubber strip to cover the spokes they wrapped a couple layers of duct tape over them.  Spent some time with the wire wheel on the inside to remove the glue and rust.  I will soak a towel in Prep-N-Etch and lay it over the inside of the wheel to take care of the rust.  It will take a bit working the towel around the wheel, but once done it should be just fine.

I pulled out the Japanese grease fittings to replace them with some standard zerk fittings.  I drilled out the holes in the swingarm pivot bolt, but when I went to tap them my bit broke.  I tried to get it out, but failed.  Luckily the SL350 I picked up from dusterdude uses the same bolt so I was able to swap them.  A new tap and some extra cutting oil and all is good now.

The rear wheel had the bearings replaced at some point with sealed bearings.  They spin nice and smooth so I thankfully don't have to mess with them.

Not sure if this will show up well via pics, but in person you can really tell a difference.  I decided to try and document my polishing process a bit more.  All I did today was wet sand the part.  Tomorrow I will hit it with the buffing wheels.

Start:






After 320.




After 600.




After 1200.




After 2000.

Not sure what I am going to do in the middle.  Sanding/polishing them would be exceptionally difficult.  Cleaning the wheels on the 750 is a pain in the arse so I can't imagine trying to get in there occasionally with some metal polish.  I am thinking about hitting the middle with a brass wire wheel to clean them up and powder coating the middle whatever color I do the frame in.  That way a simple spray and wipe would suffice.

Wire wheeled the center part then moved onto the polishing.  Again, not sure if the differences will show up via the pics, but when looking at it in person you can see a change.

After black compound




After rouge compound

"Of all tyrannies, a tyranny sincerely exercised for the good of it's victim may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated, but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." - C.S. Lewis
