Hi Mark, on your 97 engine start-up video, I seem  see the longer winkers rods on the front ...
Were they longer on the very first Sandcast models?

I am not aware of different lengths. There was only one stem on #97. It had a 19mm hex and was about 38mm between the hex and the winker base. Every other one that I have has a 17mm hex and is the same 38mm dimension. I used two NOS stems that matched the one on #97. Has anyone seen a different length on sandcasts?

I have not. Of course they went to shorter versions around 1975.

It's just a question... Because we do not know much in France of the peculiarities of the first Sandcast because the first arrival "official" is dated at the beginning of October 69 and set aside the 313 we have never found trace of the 73 bikes of the month of September 69 or it was marked "California" on the wooden crates containing the bikes.
And how much does the stem in mm from the start of the blinker to the nut near the headlight bowl?

That is the 38mm dimension I referred to.

I’m am going to sell #97. I’ve had it almost 10 years and have had a ton of fun with it but priorities are changing and it's time. Besides I have at least three other projects I’m working on.

Most of you guys know about the bike, but to the best of my ability I have put together a summary here. I’ve probably missed something but everything thing else is in this thread. For all that I have put into it I would like to see it go to a good home so I’m reluctant to put it on eBay, although maybe that would be just fine. But if anyone here is interested I would like to give you a shot.

I’m trying to come up with a price and I’ll be checking out the Mecum Auction in Las Vegas (maybe this isn’t the best timing). I will say I don’t want to give it away. It’s pretty special and very correct. There are maybe 15 2-digit sandcasts in the world (probably less than half that number in the U.S.) and only a few as nice as #97. If I get the right offer it’s gone. If anyone is interested reply here or PM me.

Good luck with the sale Mark.  I hope it goes to someone here who appreciates the level of work youve put into the bike.
All the best, Steven.

I have seen this bike in person. It is easily one of the best restorations I have ever seen.

You will miss it Mark! :)

Thanks for the for the kind words guys.

You're probably right Sam.  :( But I have three other projects to keep me busy. At least one of them is 3-digit.  ;)

I have finally decided on a price. After seeing the results at the Mecum auction and talking to several knowledgeable people I have decided on $69,000. I know some people may think I'm crazy but that's what I'm asking. If you're interested please contact me.

Priced low. For a bike of this caliber restored at this level, $69k is a great deal.

After the recent eBay auction for KP’s 2-digit sandcast I’m lowering my expectations for what I would like to get for #97. I started high for probably obvious reasons but I am lowering the price to $60,000. I will consider offers. I have three people that have expressed interest but no offers yet. If anyone is interested feel free to contact me.

This is one of the highest quality restorations that the community has seen, was featured in one of the world's top museums and is fabulously well-documented. It's all there folks. Someone is going to get a deal.
