I would really liked to have the frame... buuh 

I am starting to restore an 2/70 K0 with frame number CB750-1022139, and I am need to know some detal about some parts.

On what Serial number started the:
- HM300 mark on the exhaust?
- The white foam for the seat?
- The long Chain guard
- Ended the rear rolled rim?
- Ended the recessed ignitin switch
- Ended the wrinckle tank

On front fender, I have seen
- Double cutted With clamp for speedo cable
- Single cutted With clamp for speedo.
- And finally no cut on both ends-

On my CB7501018317, there is a wrinckle tank, double cut fender, recessed ignitin, read foam and rolled rim, unmarked mufflers, short chainguard, so the changes I am looking for is after this number.

I will preciate if someone have some answeer/Serial numbers on this to help me.

Maybee not the right place, but I try here also.

I am looking for a set of original 2-ring slipper type piston for my CR750 project. If someone out there have a set for sale, please email me on: jan@tveten.biz

ok. I am building a kit bike, so not the right thing for me actually. No big deal that I dont get them. But if you are building a dick man replica, it is the real thing.

Hmmm.....
I just start to think that someone is trying to scam me on this bike. The photo's Mike listed is the same Picture I got from the seller. When I google'd the frame and engine number, I got this tread....

There it is stated that the engine number is a sandcast, but it could not be the same on the photo.

I Guess I will not receive any phot of the frame,  engine number and title.... I always ask for this before I pay for a bike.

But back to the beginning, it looks like an interresting bike. Later Production bike With sandcast engine..

Maybe. That is why I have asked for a photo of the engine number to see if it is re-stamped.
