I have a 1980 KZ750H LTD. Can I do the same conversion with my bike.

I didn’t find any reliable numbers quantifying performance numbers. I think the only reason to do this is just the availability of the 530 vs 630… and maybe just the idea that it improves performance.

The myth is true…
Going from a 530 chain to a 520 chain yields an increase in 1.5 hp / tq.

So…
Going from a big ass 630 chain to a 530 chain should prob be even more. Maybe 2hp.

Shit, i’m gonna go from a 630 to a 520 chain on the z1 and get an extra 3hp?!?
Watch out Adam, your KZ has no chance…

I’m also running a 630 o-ring chain on my Z1… and i’ve never had to tighten it once, after 5k miles. Love it.

I’d be really interested to see what type of “perceived performance” or “reduced drivetrain powerloss” you get from going to a lighter 530 chain.

It’d be interesting to be a 1/4 mile run before and after.
Or a dyno measuring rear wheel power.

If it was anything noticeable, i’d switch to a 530.

Thanks Adam. I’m thinking about doing the conversion on the 1000 this winter. Currently I am running an 630 o ring without any issues.

Weird sprocket/chain config for the late models. Your new setup should be a lot better. For my 79 KZ650 I went with 17/42. It’s an easy adjustment to drop the rpms around 1k or so during highway cruising. Here is my KZ650 setup.

530 (JTF513 Series) 17T Fr sprocket
530 (JTR481 series) 42T Rr sprocket

Yup, I haven’t put the chain on but the oring chains should fit fine. I dont think the KZ had enough clearance to fit the $150 630 oring chains.

does this also open up the availability of running the $100.00 o-ring chains? For us that believe any form of lubricant is a crime.
