1982 1100E 530 Chain Conversion Thread

Z1's website says the spacer is to replicate a boss on the 630 sprocket that provides clearance for the chain and cases. It says the boss is on the inside. When I mocked up the spacer/sprocket combo, the spacer on the inside put the sprocket in the exact same position on the shaft as the old one, determined by measuring the remainder of the splines that protrude from the center of the sprocket. Is the rear sprocket of a different offset than the stock on? Without measuring, it looks pretty much the same. This is the wording from their website:

Sprocket spacing is important too - on the two front sprockets above, you will see the 630 version has a slight boss (raised area) to the inside - to be able to switch to the 530 equivalent sprocket, spacers must be added to give enough clearance between the chain and the engine cases.

Wrong answer,

As seen below, the stock sprocket has the 6mm damper sandwiching the sprocket. What it does not show is the id of the hole on the other side is larger for the bushing to slide into. The bushing rests against the sprocket itself. The sprocket on the 82/83 750 and 1100 katanas are flat. no boss. The sprockets I have removed from other 1100 motors have been the same.

undo the three screws on your stock sprocket ( will need an impact driver) and see for yourself and report back. Spacer goes to the outside as you can see in the picture. The nut tightens up against spacer.

In the second picture of an actual stock 630 you will see there is about a 0.040" recess in each side of the sprocket were the damper lives (Not a 6mm). This is just cut into the side of the sprocket and the outer edges are flush with the teeth of the sprocket.

spacer is for the outside of the front sprocket. the stock 630 coutnershaft sprocket has a dampener of sorts and the 530 does not. if you don't use the spacer then the nut won't tighten down on the sprocket.

What ratio would you use to keep rpm @60 m.p.h. the same as stock 630 chain or is that as close as you can get,I would like to keep r.p.m the same or lower at highway speed, just fine on low and mid range??

17/48 will put you within 32rpm @ 60mph on the good side. In other words you will be 32rpm higher @ 60 all things being equal.

16/45 will get you to 17rpm higher but they are quite a bit smaller in diameter than the 15/42 630. Even the 17/48 sprockets are smaller than the stock ones. You just have to watch pivot clearance for the chain if you get soo small with the sprockets.

he has gone with a 16/48 ratio to livin up the bottom end and midrange. the diff from stock ratio is about 9 mph less top end and almost 300 rpm higher @ 60 mph on the highway

In my former life (before retirement) I worked for a few years as a MFG ENG .... nice process sheet! BTW what is the spacer for? Chain alignment?

Thanks

What I like is the 8 lbs of rotating mass you lose when you go to a 530. YOur engine will thank you.

List, nice, wish I was better at making them!

Yes, gonna run the 3 spoke 5.5" bandit wheel. The same exact wheel is on the non-titled RF900 I got for $200 and have been parting out. I have to get a chance (maybe this weekend) to pull the rear wheel on the E and see if it will fit with a 170 tire, or if I'm going to have to do a swingarm conversion (probably), but I also have the RF900 swinger (heavy parts are harder to sell because of shipping cost), and odds are it can be made to work. It already has the mount for the torque arm mounted on the bottom to covert to the RF900 brakes, but it's a monshock, so have to fab the shock mounts..

Yep, this is in my future for sure. Not sure how my potential rear end mods effect it.

You were planning on a different rear wheel, right? Probably just have to locate the correct rear sprocket, and make sure both sprockets line up correctly. If you have to replace the chain, might as well do the conversion. Price is cheaper than doing a 630 chain and sprockets, and you get a wider selection of parts. Front and rear sprocket, chain plus the spacer and a masterlink, ran me just shy of $170, shipped, from Z1. Same setup for a 630 is nearly $200, before shipping, even without the added expense of the spacer.

have not done 530 conversion even though everyone says i should but if the 630 is that hard to find might have to?so I will be looking at this thread to see how it goes

Slowly working at getting broken/inadequate bits replaced on the GS as swiftly as funds allow. Man, when you're drooling over parts, those two weeks between paydays seem like years. This thread's going to be about a few specific parts, mostly the chain, and both front and rear sprockets.

I attempted to locate a 630 chain when I discovered a few FUBAR o-rings in my OE chain. I gave up after my twenty-third negative response, and decided to just go ahead and complete the 530 conversion. So, parts were ordered, shipped, and they arrived yesterday. I'll probably wait until the weekend to commence the conversion, since I'll have Saturday and Sunday off, and I'd much rather take my time and be as particular as possible while turning wrenches.

So, my parts list is currently:

1 - 48 tooth rear sprocket
1 - 16 tooth front sprocket
1 - 6mm spacer
1 - 114 link Rk XO-ring Chain
1 - Chain masterlink

Here's the plan, in a step by step fashion, let me know if I've missed anything:

1. Remove chainguard
2. Remove front sprocket cover
3. Untorque front sprocket bolts, using a block of wood and the bike's brakes to stop the sprocket from moving
4. Break and remove chain
5. Remove front sprocket
6. Remove rear wheel
7. Remove rear sprocket
8. Install front sprocket on front sprocket shaft
9. Install 6mm spacer on front sprocket shaft
10. Install rear sprocket on rear wheel
11. Install rear wheel
12. Install chain onto both sprockets, test for length
13. Size chain to fit, if needed
14. Install masterlink, closed end towards the direction of travel, with a glob of silicone to ensure it stays put
15. Re-adjust rear wheel for straightness
16. Re-adjust chain for optimum slack
17. Clean factory preservative off chain
18. Lube chain
19. Double check everything
20. Double check everything - again

How's it sound? I miss anything? When the weekend rolls around and I actually start this mini-project, I'll populate this thread with as many pictures as I can. I went with the 16 tooth front for a touch more pep around town. I usually only do one 200-300 mile rides a month, the rest of my time is spent commuting at around 45-60 MPH, and I think the 16 toother should be just about perfect for my style of driving.
