Still a mystery as it was running and going flawlessly.My stock chain went 48,000 miles on a diet of PJ-1 Blue Label.I replaced it with the then-current EK VX-2 X-ring chain.  I did not replace the sprockets, as they looked fine to me.The EK chain had 58,000 miles on it when I sold the bike, still spinning on the OEM sprockets.  The chain was still quiet-running, virtually kinkless, and still within the specified stretch limit on the 21-link test.And the sprockets were still decent-looking.Needless to say, it's been all EK VX-series X-ring chains ever since.Bill ZellerLemont, IL(FJR1300, CBR11 Blackbird these days, a worthy replacement for the ZX)On 10/17/2025 2:00 PM, gpzlist-request at lists.micapeak.com wrote:> Send GPZList mailing list submissions to> 	gpzlist at lists.micapeak.com>> To subscribe or unsubscribe via the World Wide Web, visit> 	https://lists.micapeak.com/mailman/listinfo/gpzlist> or, via email, send a message with subject or body 'help' to> 	gpzlist-request at lists.micapeak.com>> You can reach the person managing the list at> 	gpzlist-owner at lists.micapeak.com>> When replying, please edit your Subject line so it is more specific> than "Re: Contents of GPZList digest...">>> Today's Topics:>>     1.

Well, I verified the 5/8” pitch value, but when I measured the chain width, it measures 3/8” between the inner plates, which would make it a 530 chain, not a generically equivalent 520 chain as Enuma’s website claims. Please explain. Also looking for experience based replacements for the OEM chain.>> Drive (front) 17T Sprocket:> This sprocket is NLA from momma Kaw, so I’m looking for generic equivalents for this item that are otherwise identical to the OEM piece.>> Driven (rear) 45 T Sprocket:> Although this sprocket is still available from momma Kaw, I’m thinking that there are other equivalent alternatives to the $119 OEM piece. Experience based suggestions encouraged and appreciated.>> That is all, and I appreciate any insight and recommendations based on your own experiences. I look forward eagerly to your replies.>> Best regards,> Bill Denton> Yardley, PA> 267-980-7788> WKDENTON at VERIZON.NET> Lazarus CycleWorks> We Breathe New Life into Old Bikes>> Sent from my iPhone>>> End of GPZList Digest, Vol 181, Issue 1> ***************************************______________________________________________________________________GENERAL GPZList MAILING LIST INFORMATION:This is from the GPZList mailing list.
