I could use the American and Canadian part #'s for those cranks, if you know them.

Hey Fishy...
I can't find the parts numbers online as anything online is US.
The next time I'm at the Honda dealer, if they aren't busy I will get them to look up the part number.

The part # for the Cdn crank is:
13300-MJ1-000
it is then superceded by part #
13300-MJ1-010

Both are discontinued

American Honda 700 crank is currently 13300-MJ1-671 (1986)
It was 13300-MJ1-670 in 84 & 85.

I ain't puttin' no canuck crank from a 750 that carries a different part number in my 700..... poke bugey
Here's the real deal with rods.

I don't blame ya...

If anyone ever wanted to upgrade their 700 to a 750, I would recommend buying a Cdn 750 engine and just do an engine swap.

I guess that's a matter of opinion, the expression of  "upgrade to a Canadian 750"...... scratcher

Well its not worth it in my opinion....
I ran mine off the line with a 700, when I met up with Scotty13, and they were both the same. Whatever difference there is could be the weight of a full tank of gas to an empty tank = there really isn't that much difference.

I was looking through this post and wanted to address going backwards: I have 84 CB700SC and seen a 82 cb750 motor in my area for cheap I might be getting ahold of I am in the process of talking with the seller but wanted your thoughts on it?  It's only 100 obo hopefully the guy messages me back.  I have just recently picked up two 1984 CB700SC burning and leaking oil, second gear is shot, among other issues.  Hope'n to at least get one together and maybe throwing this 82 cb750 motor into the other frame.  Might be pretty ambitious but I'd like to have both on the road.  Right now I just want to get things together for cheap and enjoy riding.

The 82 CB750 engine will not bolt up to the 700s frame. Two completely different designs.

I suspected wouldn't but had to ask...Not sure how much of the motor is there either but for 100 might be worth fabbing some new mounts up?  How as the 82 pretty solid case?

I'm not sure if mounts would be the hardest part...?
Isn't the 82 750 chain drive?

Yeah, it's more than just fabbing mounts. The 82 750 is a chain drive bike, the 700sc frame is for a shaft drive.

Thanks guys I'm learning as I go!  I really appreciate the information as I didn't realize the issues I would have ran into.  I'm my worst enemy sometimes, you guys are great.  I'm glad I asked I would have been sitting on that motor kicking myself for not asking prior.

Save yourself all the headaches and find an 85 or 86 700 engine.
