Topic: Drive chain advice? 78' 750K

[zeus87]

Well moving, its time to do chain and sprockets.  I have the stock 630 15/41 drive set up, any recommendations?  I dont want to buy crap, but i dont want to spend a fortune either.  With there being so many choices, i figured you would know best...Thanks  ps, i hear alot about 530 chains? whats this all about?

for the first time in my life, i tried a non-"o"ring chain.  properly adjusted and lubricated, it was toast in 400 miles.  have an RK
"o" ring chain now, all is well after 4K miles or so.  looks new.  i looked into a 530 setup, couldn't find both sprockets for my bike.  supposed to be the hot set up:  less overall weight, and more importantly, less rotating mass.

Got the same bike. It depends what condition your sprockets are in. Mine are good so I picked up an Tusbuki X ring 630 chain from Loudfastugly and slipped it right on. I like the look and the price was right.

I just made the change from 630 to 530 EK x-ring chain on my K8. I have not ridden yet, since the change, but the change-over was simple enough. I have no real reason for changing to a 530, other than assurances that a contemporary x-ring is at least equal, if not superior to, an older 630 chain, in terms of strength. And since the bike had sat for nearly thirty years, and according to much other advice encouraging a sprocket replacement concurrent with chain replacement, I decided to do both. The sprockets were JT and I believe were 18 front and 48 rear. Ordered all from Dennis Kirk for about $140 plus or minus a few bucks. I could get part nos. if you need them...

DID chains are the good

ahh good deal, yeah part numbers would be awesome! i do alot of business with deniskirk.  THANKS man!

[moham]

part numbers would be awesome!

chain: 11-9922-110
rear sprocket: 81-060-48s
front: 81-116-18

FYI: I ordered a 110-link chain and used a dremmel cutting wheel to size it...then we used a couple of vise grips and a rivetting tool to press it in place. Probably not the easiest way to do it, but it worked and I saved $40 on the specialty rivet tool....(checking my receipts, it was closer to $160 everything...)
