According to the numbers its a early frame, looks like 69 but the motor is a K7 1977, if it was the original sand cast motor you would have a treasure on your hands and something worth a lot of money. Some pictures of body work and gauges would help verify the basic bike year. Is the original motor hiding out somewhere in a corner?

I think i have the engine the number on that is cb750e-1002884

The new number would be a correct motor for the frame, it is also the highly collectable and valuable sandcast. If you put the two back together you have some good money on your hands. Like said some pictures would help verify.

If it is true sand cast I am jealous!

What you need pics of

 

[dirtdigger]

Engine clutch cover have different number of bolts as does the oil pan. Oil filter cover will be smooth not finned on the sandcast. Side covers on the bike, gauges and upper triple tree. Does it have original exhaust in good shape? Should have HM300 stamped on it.

 

[pmaco1978]

It is missing the oil filter cover and the other side cover and i am looking for all the side panels for the bike

 

[dirtdigger]

Count the bolts in the clutch cover. Any idea why the motor was swapped? Case broke by the sprocket?....most common reason...the drive chain would break and go through the case.

 

[pmaco1978]

I hace no idea bit i did find the sprocket cover and the clutch cover jas 10 bolts and three in the center

 

[pmaco1978]

This is the bike it self

Gauges setup isnt stock for the year, looks like a lot of non stock parts. 10 hole is not sandcast...must be replacement cases with the old case engine number stamped in.
