Ready to ship

Vic sent us some more pictures of the CB750. It was picked up in San Francisco on the 20th of February, at this moment it’s somewhere on the ocean heading here in its crate. Until it arrives we’ll have to make do with the pictures.

No 742

A little over a year ago the red Sandcast Honda CB750, that Vic over at world motorcycles restored for us, arrived. Well, we sort of got a taste for them and asked Vic to restore another sandcast CB750 for us, this time a blue one, and to make one with as low a number as possible. Since then Vic has been hard at work restoring bike number 742(!) for us and yesterday he sent us this video of the first start. There’s still some work to be done, and a voyage across an ocean, but it’s starting to come together and it is running fine!

Sandcast CB750

A year ago we contacted Vic at worldmotorcycles.com about restoring a sandcast 1969 Honda CB750 for us. You can see our original post about it here. It arrived in it’s shipping crate a few weeks back and had to clear customs. This is our first “unboxing”. Vic’s done a great job with it!

The very earliest CB750’s that were produced were this sandcast version: the crankcase was created using a sand mold. After engine number E1007415 the engines were die cast instead. Couple this with the fact that the early chains were to weak for the engine which caused them to shatter the crankcase and you have very few of these about 7000 bikes produced left in existence with their original sandcast crankcase. This is one of them.

Mark Haycock wrote in his book about the CB750: “This is properly identified as the CB750. Not K0 or K1, just CB750. This fact seems to cause a lot of confusion throughout the world. Perhaps it would be wise to use the title ‘pre-K1 CB750′”, so we’ve chosen to do just that. K0 was coined in retrospect and not an official designation.

The engine and frame serial are both around 2500 so it even has the horn on the left side behind the front brake hose, this was changed to the right at frame number 1003951 since the hose would foul the horn. We’ve taken the bike to its home in the museum but haven’t snapped a full gallery of it yet, until then: you can enjoy these snapshots and our unboxing video :)

Sandcast Honda CB750

A while back, in December, I posted an update about visiting Vic World in San Francisco. Since then he has been working hard on restoring a sandcast, 1969, Honda CB750 for us. It is almost complete now so I thought I’d share some of the pictures he’s sent us of the restoration process.

For those of you wondering what’s special about the early, sandcast, version of the CB750, visit Vic’s website and read more.

Once the bike has arrived in Sweden, we’ll take a whole bunch of pictures and video of it running.

San Francisco and Walkthroughs

It is time for the next walkthrough on the AS3 Europa! This time we’re covering the assembly of the footrest, the rear fender and the rear wheel. Click here to go to the update.

Now on to something more exciting. As some of you might know from an earlier update, I am in the US at the moment (hence the updates at strange times). What you definitely don’t know is that we’re planning on getting a new Honda CB750 to our collection. We have a K2 from 1974 (in Europe they kept the K2 moniker longer than in the US) but we thought we would round it out with the original 1969 sandcast version.

The ones of you who are into CB750’s know that there is only one person to talk to when you want a sandcast 1969 CB750: Vic World. At the moment he is hard at work restoring a red sandcast for us. I took the chance stop by and talk to Vic in San Francisco on how he goes about a restoration.

The choices both we and Vic face are quite different from what you would face when you’re working on a single restoration. We have the advantage of performing several restorations which means we can prepare a lot of parts in advance and work more using modules. When you’re performing a single restoration you’ll need to prepare the parts specifically for that bike which takes more time and money.

Vic has built up a lot of NOS parts specifically for the sandcast versions, you can see the shelves full of parts in the pictures below. So far our CB750 is still in modules, strategically placed around the workshop, but you can get a sneak peek of the rebuilt carburetors that will eventually go on our CB750.

I got a lot of good advice from Vic and I’m struggling to put it into text here, just know that when you come to us with questions about restoring a motorcycle, I know more now than I did before!

Hidden in the background is the race version of the CB750 Vic built a while back. It is one of only a handfull in existence. Rebuilt from the ground up with original CB750 racer parts and skillfully created titanium parts made by Vic himself. He later competed with the bike at Daytona in 2000 and 2002 at classic motorcycle races. Click here to go to his website and read more about both sandcast CB750’s and his racer!
