530 Chain conversion

I'll send you my front if you want. Only a year old. Won't be able to use it after I put in my 550 gears.

Exactly!
And thats why i didn't use a spacer when i did the 630 to 530 conversion last year

Per Dave Marsden (Eminent Historian) History of Kawasaki Z1 and KZ
Section regarding 1975 Z1-B
(original in all caps)

REAR DRIVE CHAIN AND SPROCKETS:
DUE TO COMPLAINTS OF THE DIFFICULTIES IN USING THE AUTOMATIC CHAIN OILERS OF PREVIOUS MODELS, THE Z1-B WAS FITTED WITH AN O`RING CHAIN. ANOTHER FIRST FOR KAWASAKI. THE NON O`RING CHAIN WAS NOT REALLY UP THE JOB ANYWAY, SO THIS WAS A GOOD MOVE.
THE WHOLE OF THE CHAIN OILER SYSTEM WAS REMOVED.
THE CHAIN WAS ONCE AGAIN AN 'ENUMA' PRODUCT, AN EK630S-TO X 92 LINKS.
BECAUSE OF THE EXTRA THICKNESS OF THE CHAIN, CAUSED BY THE O`RINGS, MANY OTHER PARTS OF THE BIKE HAD TO BE MODIFIED. THE CHAIN WAS 0.11 OF AN INCH WIDER.
THE FRONT DRIVE SPROCKET HAD TO BE SPACED OUT FROM THE INNER TRANSMISSION COVER, SO A MODIFIED SPROCKET WITH A BOSS BUILT INTO THE BACK OF IT WAS PRODUCED. BECAUSE OF THIS, A THINNER LOCKING NUT WAS ALSO SUPPLIED.
THE REAR SPROCKET REMAINED THE SAME BUT A THIN SPACER WAS FITTED BETWEEN THE SPROCKET AND THE CARRIER TO SPACE IT OUT. BECAUSE OF THIS THE SIX SPROCKET RETAINING BOLTS NEEDED TO BE MADE LONGER.
THE PLASTIC CHAIN GUARD WAS ALSO MODIFIED TO A SLIGHTLY WIDER DESIGN AND THE CHAIN ADJUSTER PLATES WERE CHANGED ONCE AGAIN.
BOTH REAR ENGINE MOUNTING PLATES WERE MODIFIED, ALTHOUGH THEORETICALLY, ONLY THE LEFT HAND ONE NEEDED TO BE. ONE OF THE 8 X 40 MM BOLTS, HOLDING THE BRACKET TO THE FRAME, WAS SHORTENED TO 36MM.
ALSO SHORTENED WAS THE TWO EXHAUST MOUNTING BOLTS. THESE WERE NOW 104 MM LONG INSTEAD OF 108 MM. THE TWO 10MM LOCKING NUTS, AT THE REAR, WERE ALSO MADE THINNER. THIS ENSURED NOTHING TOUCHED THE DRIVE CHAIN.
KAWASAKI RECOMMENDED THAT THE NEW O`RING CHAIN SHOULD BE LUBRICATED EVERY 500 MILES.
NEW PART NUMBERS:
CHAIN 92057-096
FRONT SPROCKET 13144-062
REAR SPROCKET SPACER 92026-108
MOUNTING BOLTS 92003-087 (SPROCKET)
ENGINE PLATE 32030-046 LH
ENGINE PLATE 32030-047 RH
MOUNTING BOLT 110G0836 (ENGINE)
CHAIN GUARD 36014-061
CHAIN ADJUSTER 33040-066
ADJUSTER BOLT 92003-147
EXHAUST BOLTS 92003-180
LOCK NUTS 92019-021


Good Fortune!

In that case you might have to take the studs out and thread them a little further.

Yep, will do, I'm not a newby at this, just unfamiliar with the Kawasaki set up.... What wheels will you be fitting to yours..?

Nessism wrote: I used the following on my 750E. As far as I know the R1 uses the same gearing.

JTR488.40 Rear sprocket
JTF513.16 Front sprocket
These sprockets match the stock gear ratio.

530 chain with 102 links.

A 530 chain is the same width as a 630 so no spacers needed.

Stock gearing with the 630 setup is 33 rear and 13 front.

Thanks for the info Nessism, there's so much conflicting information on the net, the more you read, the more confusing it gets...!!!

Within 20 min I was walking out the door with everything including a loaner chain breaker/crimper.

My local shops should be charged for what they do to my wallet, rape is an offense everywhere else...!!, Luckily I found an online distributor who's based about 20 minutes from my house, I contacted him last night and he has, or can get everything I need, and at great prices...Thanks for all the help guys

A little chain FYI

530: first number is the length between pins in x/8", so in this case 5/8" between pins. Second number is width in x/8", so 3/8" wide.

630 is 6/8" wide (or 3/4"), and the same 3/8" width.

Understood...

This shop is more expensive than online but not extravagantly so. I buy from them when I can. If they go out of business they won't be there when I really need a part and don't have time to wait for an online order.

I'm glad I found the local online guys, they are up too $60 dollars cheaper on the chain i picked than the local shops...!!!

At $60 cheaper just make sure its not made in China

I should have added that because there's no shipping as well, I'm picking it up from the warehouse, Its an EK chain and its made in Japan...
