No,  520 is a narrower 530. 525 had different distance between the rollers.  Tooth pitch,  if you will.

520 is 5/8" pitch x 1/4" width, 525 is 5/8"x5/16" and 530 is 5/8"x3/8", all the same pitch.

Love the new carbs, are they the Chinese copies and, if so, what's the quality like?

I stand corrected...  I knew that you could use 530 chain on 520 sprocket in a pinch...  Didn't know 525 has the same pitch.  Might've saved myself some aggravation if I hadn't already bought a new sprocket. 
They actually look every bit as good as real Keihins,  to be honest...  Maybe the finish is a little more dull,  but they did a really good job machining the bores and slides. I'm surprised.  And at the price,  I don't care if they fail.  I can still afford Mikunis if they do.

Good stuff. The only thing I would do with carbies is put genuine Keihin jets in, particularly the mains, as the Chinese jet sizing sometimes leaves a little to be desired. I've seen a larger jet number with a smaller hole which obviously causes all sorts of problems.

Indeed. I know I'm gonna have to change the jets anyway. Might as well get the good stuff.

I made my first attempt at fitting the Rebel 450 engine into the Yamaha frame.  After I cut off all the original Yamaha mounts,  it'll go right in.  Then I need to fab up new mounts.

I decided to replace the lower frame section of the Yamaha with the part of the Honda frame that holds the motor mounts.  I figure it's easier than trying to make room in the Yamaha frame as it sits, plus it allows me a little room to place the motor where I want it.
Anyone need some Rebel parts?

You know, it's not as bad as people think.  Especially the later models.  By '78, they really had it nailed. I mean,  think about it. You had a DOHC, 4 valve-per cylinder design with a balance shaft,  and by then they had everything set up to be either self-adjusting,  or extremely easy to do.  And they had higher horsepower then any other 500 twin for years.  Even the Ninja 500 didn't make as much power. Yeah, they had quirks, but when did any design not start out with some issues? Yamaha fixed everything,  then gave up.

Cool, they have a horrible reputation here, tx750's being the worst. Apparently all balancer and oil froth issues can be solved though.
