Mark, good luck with your sale.  It is well worth your asking price and then some.

Thanks Kp for the great info.  I'll keep my eyes out for the single digits!  I wonder what happened to the the first four bikes.  Are they in the Honda headquarters?  What would be the value of a single digit and double digit sandcast?

About a year and a half ago I saw this ad for a cb750 that was being parted out.  The picture on the ad was that of a ruby red CB750.  It had only one picture and not much information.  The seller was parting it out.  I messaged the seller to see if I can save this bike, however he did not respond.  I saved the ad and for about a year and a half I messaged him probably 20 times asking if it was still available.   The ad had been removed from the website but for some reason I could still view it because I had saved it.  Well long story short, the guy messages me back about 2 months ago and asked if I was interested in the whole bike.  I asked him what he wanted for the bike not knowing that it was a sandcast.   He said what do you have to trade.  I asked him what he was planning to do with the bike and he had told me he was going to remove the engine to place in a golf cart project that he was planning.  I offered him a trade - his CB750 project for a 1982 CB900F engine which he could use instead of the sandcast engine.  He said yes.  So we do the trade and I had the bike delivered to my house while I was on vacation.  When I finally got to see what I had traded for, I was so disappointed to see that the numbers on both the engine and frame had been altered.  The bike however must have been quite early as it had a left sided horn mount, thin lipped alternator cover, 19 liter tank and short petcock.  The bike also had the double cut fender and rear rolled rim.  I was trying to figure out what I should do with this bike.   After much contemplation, I decided to keep the bike and maybe build it out.  I could probably get it running and road worthy.

Hi there Jean-Louis.  Welcome.  Very nice gold Sandcast.  it looks like it has an early cut-off switch without a pointer.  What's the history on your sandcast?

This is an amazing piece of engineering and was awesome to see and hear at the Quail with Sam.  It was probably the loudest bike there.  Also to get the 13:1 compression that Vic was able to get from an early Sandcast engine is a remarkable feat.  The amount of rare parts that are on this bike makes it nearly one of a kind.  Vic mentioned that the gears were hand made, the cylinder head valve cover was engineered with bolts that run through the cover and stabilize the rocker towers, and he also said the clearance of the vavles and pistons was so close and precise that the pistons would "self clean". I posted a video of Sam starting the CR750 on Youtube.  https://www.youtube.com/watch?v=qgpudMsulzo

I just wanted to mention our very own Sam (Ujeni) won best in class and won best in show at the 2019 Quail Motorcycle Gathering. It was a great event and great weather for a motorcycle show on a golf course. Makes me want to get one sandcast ready for next year!

I located this guy on facebook and messaged him calling him out for messing up an eBay item that I had.  He acted like he did not know what I was talking about then blocked me.  He has two ebay names and uses one to outbid his other ebay name.  He did this to get out of paying an auction that he won.
