Sandcast #97 restoration
« on: November 01, 2010, 03:57:36 pm »
I've finally started this project after picking the bike up this past spring.  I spend my summers boating and fishing and do little if any work on the bikes.  I've got two other 750's that I've restored, an early diecast and sandcast #5383.  I'm going to post this on this forum and the SOOC forum so some posts by me will be identical but the replies will probably steer it in different directions so I'm not sure how that will work out.  But I figure that way I can get feedback from two different audiences.  My goal is to make it as correct as possible which I realize may be next to impossible because of the rarity of some of the missing parts.  There's plenty of work to do and plenty of missing parts.  I'm looking for all the advice I can get and if anyone has a part that I'm missing and you can part with please contact me.  I know they won't come cheap.  So for my first post, here's what it looked like when I picked it up last spring.







What a great motor number

Mark, not sure I understand the four identical links to the same current sandcast auction on eBay?

No it was part of the price...oh, do you mean does it turn over?  Unfortunately not.  More about that soon.

There's got to be a story about how you found this bike or it found you. Number 100, amazing! I wonder how long the assembly line was running when it rolled out the end all shiny and new.

I'll use it everywhere.

I have no reason to believe it doesn't but I haven't got that far yet.  I'll let you know.

I actually found it from a posting here on a CL ad.  A custom bike shop in Oklahoma picked it up locally and I made up my mind I was going to get it.  The seller was out of town so wasn't answering his emails right away but through a little detective work I tracked down his shop and got his phone number and called him.  I got lucky.  We'll see how lucky once I get into it more.

All I'll say for now is too much?

First thing is to start the tear down.  I hoisted the bike up and dropped the front wheel and the three exhaust pipes that were there so I could put it on my cart.  I have a stand but it only puts the bike 18” off the ground and I hate kneeling and bending over.  The pipes disintegrated during removal.  I soaked all the nuts and bolts with a 50/50 mix of acetone and ATF.  I’ve used it before and seems to work great.  It separates though so you have to keep shaking it.


It must have been set up as a cruiser.  It has old running boards and crash bars.  I’ll get rid of those first.






Then I pulled the front end, fender and forks.  The headlight bucket and ears were completely broken as well as the speedo.  Good thing I have one of those.  Looks like someone took a baseball bat to them.  I think the tach is salvageable.


The tops of the fork tubes look pretty gnarly.


At least the front fender is correct and solid.


It looks better without all the junk and broken parts on it.


It’s missing the kick-starter so I put one on just to see if the engine would turn over.  Nope.  Tried moving the shifter too.  Nope.  After that I drained the oil…and water.  A cup of water came first then about a quart and a half of oil.  Nothing in the oil tank (although it is well coated inside with a layer of oil and dirt) or oil filter housing.  Ruh-roh.  Not a good sign.

I'm going to post this on this forum and the SOOC forum so some posts by me will be identical but the replies will probably steer it in different directions so I'm not sure how that will work out.  But I figure that way I can get feedback from two different audiences.

No worries about that at all.  I've had some custom computer case mods that I did the same thing with - type out an update, copy it to both forums, answer/respond to any questions/comments that come up.  Twice the audience for the same amount of work (well, twice minus anyone like yourself that's in both places.)

What a great motor number

It's 68 in binary.  Not sure if that means anything, but there you are.


EDIT:  Forgot to mention the obvious - I will be watching this build.  I know little about the 750s, and would never even think to attempt a project like this.  Nothing but respect for those that do.

Interesting observation.  So in a way it's a 2-digit engine too. ;)

Just a bit more history before I get too much further.  The license plate on the bike was 1979.  The seller told me that it had been sitting and then an attempt was made to get it running again in 1986.  They never succeeded because they couldn’t get the carbs right.  So, I was told, it sat in a barn (don’t they all) until he obtained it.  (If it was in a barn it was a leaky barn.)

Anyway, one of the first things I discovered was it had the 19 liter tank and in pretty good shape at that.  The badge recesses had been filled in and unfortunately the cap and short-neck petcock were missing.


By the way, does anyone have a short neck petcock they could sell me?  This is a high priority for me because it is one of those really visible things.

Note the lack of dimples in the area where the carbs tops are.


I could tell from the bottom of the tank that it was originally candy red and after some debate I decided to keep it the color it was born which happened to be the same color as my later sandcast.  It’s already been internally derusted and coated and repainted and looks great.  Blake Conway who did my others did this one too.

My K0 was the blue/green so I put that tin on the other sandcast (so I could have one of each color) and I plan on using the red where I need too and borrow parts off the K0 so I can maybe get #97 put together while I hunt for correct parts.  Eventually I’ll probably do the K0 in gold (even though the VIN is a little low for that).  Can’t even think of that right now.

Yea, I saw that one.  I was slightly interested in going to take a look at it.  It's about 2 hours away.  If it was older and had more of the stuff that I'm missing, I'd be all over it.
