Merry Christmas from the Yamaparts workshop. The elves are hard at work
/Joacim and Ole
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
Since a while back we’ve been working with a vintage Yamaha club in Indonesia: Yamaha Lawas (directly translated Old Yamaha). Yamaha Lawas was founded in 2012 and already have over 2000 members, their focus is old Yamaha two-strokes. Their aim is to help people with their restorations, both by providing knowledge and helping them find parts.
Herman from Yamaha Lawas sent us two shirts as a thank you for helping out with a project. Ole and I got a chance to rock them today. Cheers and thank you!
We have a new parts list uploaded to the site. This time it’s for the YCS1. As always, you can view it using the link below (or download it for personal use if you right click it), or click through to the Manuals section to view all manuals.
YCS1 Parts List
We finally got round to starting the YL1 we got earlier this summer. It took a few kicks to get it going and, as expected, the clutch had stuck together but after that it ran smoothly. Enjoy!
We're a site dedicated to the collection and restoration of vintage motorcycles, especially Yamaha's light models from the late 60's early 70's. Our focus is on the AS1, AS2 and AS3 models.
