Title: Project CB750-1004286
Post by: greggo325 on March 09, 2013, 12:07:20 PM
I found one!  It's a mid-number sandcast, and it's been off the road 15 years.  Unfortunately it has a K1 motor :-\ so I'm on the hunt for a 4xxx sandcast motor, or cases.  It's a running bike, and I paid a fair price for it.

I have a great set of 4-cable carbs, a gold/black stripe tank, and a set of stamped HM300's that are on my K6.

Welcome !

Contact Wayne, our Discussion Board Manager, he can make a project thread for you in the Discussion Board category, "Beginning to End - Member Restorations."

Any chance you will share your frame number so we can add it to the "VIN Directory" ?


Thanks Steve!  It is #4286.  As you can see, the motor and most of the original parts are long gone.


My list of parts to find so far:

K0 side covers...probably buy them from FrankenStuff over on SOHC4.net Bought.
K0 air box...might grind down the ridges on a later one
New 18" rear hoop, spokes to re lace what's hopefully the original two-hole hub
4xxx Sandcast motor or cases
Ducktail seat...Yamiya is damn expensive, but looks the most original
Fork ears
Wrinkle tank...only if I find a decent one for $300 or less - I've seen it happen

It has:
One smooth oil hose
Black kill switch
Unpainted caliper
Small taillight, and I think the original rear fender
K1 gauges...I'll rebuild them into sandcast style with parts from Lecram

Here are the carbs I'll be using.  We discussed them here before ;) They are known to be from a sandcast, and check out the difference in choke handles from another 4-cable set..a little fatter and rounder.

There is a frame vin #1004286 with motor #1004491 already listed in the registry, double check the numbers to insure they are correct. Is it possible you bought the bike from an owner who previously registered the vin on this web site. The bike looks to be mostly a CB705 K1 put onto a sand cast frame. Good luck and enjoy the restoration.  Marty K.


I do see that, and the bike has been off the road since '98 according to the tags.  I wouldn't be surprised if the owner previous to the guy I bought it from had harvested many of the good parts for another bike.  I guess I'll find out once the paperwork goes through the DMV.  The frame stamp looks original to me.  Is there any contact info for that owner?


Here's my stamp, there is no tag on the other side of the neck.
(http://cb750sandcastonly.com/coppermine/albums/userpics/10005/normal_2.jpg)

i think there's 2 wrinkles on ebay now.


I have seen those.  One looks to be in horrible shape, and the other one the seller wanted $700.  I'll use the gold body work from the other bike pictured until I've collected all the parts, and I'm ready for a tear down/rebuild.  It seems patience is a virtue when seeking out all these parts, so I'm in luck there.  I also have several other bikes and projects to keep me entertained.  I have a '65 CA95 Benly, a '71 CB500 Four, and a few others in various stages, including that K6, which will get some different body work, and carry on for some more fun.


How old might the entries be in that registry?
 The last tag is '98, so maybe someone had a complete sandy needing whatever, and used a crashed K1 to finish this one back to salable condition.  I ran all the numbers through the free databases, and they came back clean, so I'm not really worried about it being stolen.  I think the VIN stamp looks legitimate as well.



As cb7504 said, this bike seems to be K1 bike with Sandy frame, because front fender, front forks, ignition switch and seat lock is K1 as well. Especially K1 seat lock on Sandy frame is very strange.


Yes, mostly K1 parts on this bike.

I was able to gather some history...The gentleman I purchased 4286 from bought it six months ago from a wrecker/towing guy, who had had it sitting since 1998...the last time it was registered.  Seems that at some point the engine, gauges, front end, and many other parts were harvested, likely to save another sandy.  So far, nobody seems to think my VIN has been altered, so I think it just means I have more parts to find.  




Okay, picking it up Saturday, but I walked down to the shop it's at (PO was having work done) and snapped a few more pics to see what I'm getting. No cut fender, a three hole rear fender, the wrong starter/kill switch, wrong oil tank,  but the frame is solid, and I think it has the correct headlight bucket...and that's a short list of what I noticed today.  I did find #8 bolts all over the place, so that made me a little happy ;D

My dad and I picked up the bike this afternoon, and I got a great surprise when we arrived: the original wrinkle tank ;D  It's pretty trashed inside, but we will have it repaired by a skilled bodyshop man my dad has known for 30 years.  He worked some unbelievable magic on a CA95 tank that we had all but given up on.  

Are those the correct fork lowers?

I can't tell the difference after examining some available photos.  Could you let me know how to tell them apart?

Thank you

Where the rubber dust cover meets the fork tube the K1 is thick at this point and gradually transitions down the tube. The K0 is thick at this point but the transition is much more abrupt and a distinct ridge can be seen on the K0 tube. Someone may wish to post a picture.

the lower fork legs should have a distinct lip around the fork leg just below the rubber gaitor. as the early fork seals where smaller and prone to leaking, they tried to resolve this by removeing the metal fork seal washer and using thicker oil seals. by the time the k1 was released they made the bigger leg to hold the bigger and thicker oil seal

greggo325,
If you are going to clean the tank. I'd use some rust remover from AutoZone or Harbor Freight "Evapo-Rust™"  Rust Remover. Fill the tank up with this stuff. let it sit for a few days then check it. You will use this stuff over and over to remove rust on other parts. Also once the tank is clean, have a liner ready to go inside.. Do the de-rust and liner after the body work is done. If there is holes in the tank, no matter how large, a product called Kwik Poly http://kwikpolyllc.com/ (http://kwikpolyllc.com/) is what I use to strengthen/line and fill holes in gas tanks. Just put a piece of duck tape over the hole to keep the KP form leaking out. I'm sure everyone has their favorites, and this is mine. Great stuff.

Hey, thanks for the advice!  The tank is going to a body shop owner my dad has known for decades.  He rescued my CA95's tank after sitting for years with a poorly done Kreem job, and a layer of rust underneath that.  It was so bad I feared it was a complete loss, but somehow Carl saved it.  I think he has a radiator hot tank or something similar.  He works some magic over there ;D All efforts will be made to save the wrinkle tank ;)

It took a few months of searching, and lots of help from forum members over on SOHC4.net, but I've found a sandcast motor, and it's an EARLY one.  CB750-10003xx ;D ;D ;D  It's missing the correct head, and clutch cover at the very least, but I just couldn't pass up such an early motor ;)  I'll post up pics when it arrives.

It looks like the Engine # pad changed shape over time, am I just dreaming this?  I look at #100 on MarkB's 97 bike, and it also has the same shape as #371.  Is this a change that's been noted before?  I also see a square shaped raised pad just above the # pad.

Yes, the vin pad topic has been brought up before. There were two versions of sand cast case vin pads early version was 11mm wide and later version was 19mm wide. There appears to be no definite vin cut of point for this change. Marty K.

I'll post a few here, and I'm very eager to hear a verdict on the alternator cover.

Enjoy! I sure did ;)

I've been posting most of my progress over on SOHC4.net, but here's a quick update.

Everything's been torn down to the frame and motor.  The wrinkle tank has been cleaned with Evapo-Rust, and a couple dents were removed by a paintless dent removal guy who goes by Dent Dynamics.  He does great work for great prices.  All the bodywork is ready for paint just as soon as I buy the tank stripes.  Motor 371 is still sitting as is, waiting for an inspection/rebuild.  The running K1 motor that came with the bike is what I'll use until I can do the motor up right.  I found a true sandcast head and cylinder set, and those will be on the way shortly!

So, here's how it sits for now.  I'm working to rebuild the wheels, and front forks so I can put a roller back together after the frame goes for paint.

(http://i1197.photobucket.com/albums/aa424/greggo325/7869FBFE-4745-4B24-8BB2-B669C60D2289-4098-00000226CEF91CDA_zpsc4bb2283.jpg) (http://s1197.photobucket.com/user/greggo325/media/7869FBFE-4745-4B24-8BB2-B669C60D2289-4098-00000226CEF91CDA_zpsc4bb2283.jpg.html)

All my black parts, frame and small bits included are at the painter.  The clear coated aluminum bits, minus the engine covers have gone there as well.  Those should be ready in a few weeks, so I got to work on the engine.  I've copied my post from SOHC4, and Hondaman is a gentleman named Mark Paris, who wrote a book about restoring 750's. 

(http://i1197.photobucket.com/albums/aa424/greggo325/null_zps1763c6c4.jpg) (http://s1197.photobucket.com/user/greggo325/media/null_zps1763c6c4.jpg.html)

The cam is definitely not stock, and per Hondaman's book, has more than .370 lift, because a fully backed out tappet adjuster wouldn't let me remove a few of the shafts, we had to rotate the motor until the certain lobes were free from their rockers...if you've read through Mark's book, you know what I'm talking about.  It has an 'O' at one end.

Everything did come out nicely, but the rockers are about halfway worn out, and the cam lobes had some wear as well.

I found a very nice surprise once I got the head off: the original sandcast cylinders!

The deeper I get into this motor, the happier I am...the pistons look almost brand new, and it turned over like a dream with the alternator bolt...the kick lever not so much, so I'll see if I have problems there eventually.  After about twenty minutes of tapping, razor-blading the gasket, then finally giving up and using a gigantic pry bar at the starter motor and cam tensioner mount (the one place Hondaman says it's safe), I freed the cylinders from the cases.

(http://i1197.photobucket.com/albums/aa424/greggo325/null_zps1420079e.jpg) (http://s1197.photobucket.com/user/greggo325/media/null_zps1420079e.jpg.html)

I got everything required to split the cases, and I stopped before flipping it over and undoing the bottom case bolts...top bolts are off.  I forgot to take pictures, but the tensioner rubbers look BRAND NEW...there was barely one little wear mark on the slider, and the wheel was not chewed up at all.  I've decided to use the new Cyclex parts, and save these nice used ones for another motor.  It looks as though someone rebuilt the motor with the .50 pistons, and barely put any miles on it.  This may turn out to be a really simple refresh for this motor :)

In other news, the painter sent back the battery tray so I could decide on the gloss level...it's perfect, so he'll get started on the rest soon.

They're apart!  Everything went relatively smoothly for my first 750 tear-down.  Figured out that the pistons have to come off to remove the crank from the top case. 

I pulled the oil pan first, and only found a few metal scraps, and some primary chain tensioner rubber bits (yes, it needs replacing).  It looked like the bottom end never came apart for the most recent rebuild because I found a riveted cam chain ::) ::)

Found what I think are crank bearing markings on the outer front edge of the top case.

Still need to remove the kick starter spindle, the top half of the gearbox, and the shift linkage.

Removed the oil pump to examine and compare to MarkB's #97.  It looks to be original.

Happy Thanksgiving!!  I got a chance to check out my painted and clear coated parts that the painter dropped off.  I think the gloss level is just right, and he was able to fix up my center stand bracket.

Thanks Pete.  I did have to pick it up from the post office instead of being delivered to the house, but there was no import tax.  At 25%, I shudder to think of what that adds to a set of exhaust pipes :o

I've had some more progress with the sub assemblies.  The wheels are laced up, and my forks are nearly together.  I need the right pliers for the bottom clip on the tubes.  Also replacing the bottom damper bolts and crush washers for peace of mind.

Thanks Pete!

I had a little more progress today, and took a shot at spiffing up one of the oil lines by hitting the fitting on the wire wheel, then shot the braided line with some black paint.  I think it turned out nice!  I'll clean the other next week and get them installed with the oil tank.

Before:

Exhaust spigots installed with new screws and crush gaskets:

Figured out that I just needed the end caps to get the swing arm spacing, so I got that back in the frame as well (I'm using the top hat bushings, and wasn't sure which pieces I needed, and how to get the spacing right)

I didn't really think about coating the metal Pete..I hope it will be okay.  Maybe I will hit them with some metal polish.

I got my tires put on, finished the front forks, and turned the bike into a roller finally.

Got a CL72 today!  It was pretty much free...motor's locked up, so we pulled the plugs and sprayed Kroil down the cylinders.

Worked on the sandcast also.  Installed the starter motor, cam chain tensioner, exhaust pipes, headlight bucket, and a few odds and ends.

I have the rest of the body parts ready to go.  


She fired up for the first time and fired on all four. Didn't even need the choke! It felt pretty great to hear my first full engine rebuild fire up and run like it should!

A sale may already be in the works, as a German fellow who exports bikes and cars from the states is very interested in buying it when I'm done.  He stopped by the shop to talk with one of the mechanics, saw my bike and fell in love with it. I have plenty left to do, but in the grand scale of things it's a small percentage of the work I've done.  Once I broke it down, I basically had a frame, a few good bolts, and two wheel hubs to start this project.  It was never going to be an all original bike, so I'm very happy with how it's turning out.

Here it is running nicely, but I need to turn down the idle.  The 2-3 coil went bad, so I'm hoping for a replacement and swapped in a used but nice looking stock coil.

I took my first ride on 4286 after a year long restoration!  I still have a few last bits to finish (like the fender stays and tank emblems/trim), but it felt great to shift into all five gears after a motor rebuild ;D

The motor ended up leaking from the cam pucks, and had to be pulled.  After installing helicoils in all 12 of the cam tower bolt holes, It's back up and running.

I still need a few last touches, but I'm just about there.
