Topic: Mable's Down (a rider again)

[Vin750]

I would recommend to anyone that is doing any chain or sprocket replacements to do everything at once. And, pry open the purse, let the Moths loose, buy a good chain tool kit, Motion Pro has one for a fair price. I have to laugh when I hear these guys asking for a "Chain Length" for their bike. WTF, If you don't have the basic knowledge, tools, or mechanical ability to properly measure, cut, and  install a chain and sprockets, GO TO A SHOP!!!!! You are riding Vintage Bikes for crying out loud. Go buy a Harley or a Beemer if you want Gravy. Get some basic tools, follow the prescribed guidelines in The Owner's Manual and you'll be fine. This isn't Rocket Science folks. You cut the chain, and then rivet it back together, or, install a Mater Link properly. If that is out of your realm of capabilities  than have a pro do it. Seriously, to quote the great Dirt Bike Magazine Editor Mr. Know It All, "You Should Have Known"

Glad you brought that up I like to get a good laugh. Now at  Desert-SOHC what sprockets size and chain length did you go with on the 530 conversion? I'm ready to get rid of my 630. I don't mind extra links on the chain better to long than to short Thanks in advance.

Excuse my ignorance on the topic but isn't the 630 chain a better and stronger chain? Why go back to 530?

And what brand of chain and sprockets do you guys use?

Chains are stronger, lighter, and mechanically more efficient than 40 years ago.  No need for such a heavy chain.

Sorry missed that quote....flybox is correct the 630 chains of yesteryear are not as strong as the 530 chains that are available today.  The ONLY reason I went with a 630 when I brought her back was that the sprockets weren't in that bad of shape to start with and to save a little cash at the time.

I bought a JT 530 conversion kit with steel sprockets in 18/38 and a 530 X chain with a riveted master link.

I got the parts in day before yesterday and got the sprockets changed and the chain feed to find a riveted masterlink.  I didnt have a tool so I bought the HF one for $15.00 since my local shop was out of stock on them.  I can say that the HF tool works pretty good once you figure out how it works and what needs to be swapped around to get it to do what you need to, but it does everything.  I had to drop 1 link from the 110 link chain for the 18/38 setup, the wheel was just to far back for my tastes.  I still need a counter cover but mine will work for now.  I went out for a short test ride and I LOVE the new gearing...it now lumbers along at 85 mph at 4,500 rpms.

Thanks just what I needed.

The "stretch" on initial break in of the 530 chain was alot...1 full turn on the adjuster bolts to take the slack back to spec.  I've never had that much stretch with a 630, hopefully it wont continue.

.it now lumbers along at 85 mph at 4,500 rpms.

 

So she's now geared for 170 mph at 9000 rpm?
Isn't that a bit very VERY tall? What do you get max in top gear now? Can you even get over 6000 rpm? My '87 CBR1000f is geared for 160 miles at 10k rpm!

[Desert-SOHC]

You sure your axle is snugged up? 1 full turn does seem a lot.

Axle was tight, maybe that was the first stretch on the chain.  Or maybe I need a stronger chain, it's a 530 X-ring with 9,700lbs tensile strength.

I've already had her to 100+ with that gearing and still had throttle left and thats good enough for me.  I may drop to a 17 counter in the future.  My main goal was to get into the 4,000-4,800 rpm range on the highway and around here highway speeds are 80+ in the slow lane.

[Desert-SOHC]

Just got back from a little jaunt and rung her out on the street and highway and the adjustment on my chain hasn't changed, so I'd say that its good to go.  On the gearing I tested the highway in 4th and 3rd and if you need motivation a downshift or 2 will make her jump and throw her well above the ton if asked.  5th has now become overdrive, enough revs to keep the battery charged, and she's smooth a glass at 4200 rpm.
