kz650c using SR wire wheel...?

Hi -
I have a 79' 650C which came stock with mag wheels. I'm doing a full euro/cafe look and I really wanted wire wheels. So I have a 19" up front which looks good and I have a 16x3.25 (or whatever it is) from an SR in the back. I put on a Spitfire 140/16 tire in the back and I'm having alot of trouble getting it to line up correctly. I need to move the wheel further left to center it, but if I do that, it appears that the chain will be tweaking the sprocket/rubber grommet out of line with the wheel and back towards the right. See my dilema? I'll post pics.

My question comes down to this - Did the SR's have different swingarms than the regular 650C's?

Not sure on the swingarm differences, my guess would be no, though.

What I am pretty sure on is that a 140 tire is a lot to put on these KZs. I only know of one member who did it, Mark Wing, and I think he had to choose the perfect tire for it. I also think he ran into the same chain issue you had, but ran with it and had no problems.

Hope that helps!

The SRs came with mag wheels as well. The '81-'83 CSRs came with spoke wheels. They do have different swing arms as far as part numbers, but that just may be for the different fittings on them for chain guards and brake line. You'd have to measure them up to compare. I think we have a few members with CSRs here.

I just reread your post so if you need to move the SR wheel LEFT of CENTER for it to be centered that means that the offset on the carrier is smaller than on the kz. Ok now is the carrier a 4, 5, or 6 type? Meaning how many "teeth" are there and how many rubber stoppers on the inside?? Another way of making it fit may be to shim the sproket but it depends on how off you are. If its more than 1/4 inch i am not sure shimming would work and keep the integrity that it needs. Post back with your findings.


Also this has nothing to do with the type os swingarms the bike is using and everthing to do with offsets.

Thanks guys,

OK: the wheel is from a CSR.

Yes, I think this is all about offsets. My question about whether or not my KZ650C shared the swingarm with the CSR was in relation to wondering if I was trying to fit a square plug in a round hole.

If I were to position the wheel and tire exactly where I wanted it, the chain would not be perfectly aligned. It would be angled slightly to the (riders) right. Which makes me wonder if the CSR's front sprocket was originally positioned farther out (riders left) than on a KZ.

The carrier is a 6 lug carrier.

So, what you're saying is that if the chain is not angled more than 1/4 inch over perfect alignment I should be okay?

Thanks

another way of putting it:

I need to move the wheel to the left and leave the sprocket where it is. Seems pretty much impossible.

we are using differnt terms here.

When you look at the chain from the back with the CSR wheel it is the rear sprocket that does not line up right. SO that means that the chain is to far outward to the side. Thus being to far to the left (as seen from behind. I have swapped wheels on several kz and never ran into offset problems before. Is the rear wheel a 16" wheel or the 18"? Are you sure this is a kz wheel? Measure the offset between both wheels it needs to be the same. If you are not sure how say so. This way you can take arbitrary measurents to at least compare the tow hubs and carriers. Need more info to help.

The KZ's used different ofset sprocket carriers , I ran into this installing a GPZ wheel on my 650 ,, I was lucky to have a few in stock .. if you line them up you can clearly see the difference

Shoe48 he isnt mixing a gpz one he is using csr to a c model.

But it is the same thing he might need to find a spocket carrier that has less offset in it , I used one from an LTD on GPZ wheel ,,

Hello everyone and thanks for the help.

I think you have me on the right track. So the measurement from the center of the wheel to the sprocket should be the same on the wire wheel as it was on the mag wheel I took off. This would give me the correct offset? I'm going out to check this right now and let you know what I find.

The wheel is a 16".

As far as whether it really is from a CSR - I think so. It was one of those Ebay deals, someone had put a new tire on the wheel and the bike got parted out so I picked it up cheap. Because the 140 tire was already on the wheel, I assumed it would fit (my initial mistake:).

The auction said CSR and I think it said from a 1981.

what mag wheels will fit 1981 kz1000 csr m1 thanks jason
